Very High Food Plant Diversity among Ethnic Groups in Northern Thailand

The combination of the high biodiversity and many ethnicities in Thailand results in extensive ethnobotanical studies, especially in the northern part of the country. Here we have assembled 7620 records from 60 references regarding how plants are used for food among 14 ethnicities in northern Thailand. The uses are based on 1182 different plant species. Vegetables are the most common food category, which contributed more than 60% of all use-reports and involved nearly 900 species. This was followed by the dessert fruit category, which included about 350 species and over 1800 use-reports. The similarity among the different ethnicities was low and the number of uses and species recorded among different ethnicities were significantly related to the number of studies that had been conducted for each group. This implies that additional ethnobotanical studies are still needed in order to conserve and compile the valuable traditional knowledge related to food plants. Many exotic species are now an important part of traditional knowledge, whereas rare endemic species are uncommon among wild food plants. This situation leads to a loss of traditional knowledge about food plants and reduced awareness of their importance. As a key to using this great reservoir of food for local people, traditional knowledge related to local wild food plants can contribute to the zero-hunger goal of the Sustainable Development Goal (SDG). More studies on the nutrient content and health properties of these plants could lead to the development of new crops to meet present consumer demands.

Strength of the connection of kernels with an ear of the trititrigia variety ‘Pamyati Lyubimovoy’ in the dead-rape stage

The development of new crops (for example, by hybridization) requires significant costs, both resources and time, and therefore justified reasons. The work on the development of trititrigia (perennial wheat) variety ‘Pamyati Lyubimovoy’ has been carried out by the FSBSI «National Grain Center named after P.P. Lukyanenko» for almost 70 years. The development of such grain crop makes it possible to apply new technological methods and technical means to realize its potential. It is also necessary to establish the applicability of existing mechanization means in its cultivation in various natural and climatic zones of the Russian Federation, where it is possible to obtain and analyze data on its physical, mechanical and biological characteristics. Despite a big breakthrough in the development of trititrigia (it was included in the State List of Breeding Achievements in 2019), there are few scientific works devoted to it and there is not enough information about it, or it is contradictory, fragmentary, and it is almost impossible to meet such grain crop in the fields. In this regard, the purpose of the current work was to obtain statistically reliable information on the value of the force of kernel separation from a trititrigia ear of the variety ‘Pamyati Lyubimovoy’ in the dead-rape stage. This indicator is important for estimating such crop properties as self-shedding after reaching full ripeness, determining the degree of heavy threshing, which will make it possible to identify the features of its harvesting by existing combines. During the current study, there were used statistically generally accepted data processing methods, namely, the estimation of release, the normality of distribution using the Shapiro-Wilk test, and the comparative Student’s T-test. The average value of the separation force along the entire ear length was 5.16 N. When dividing the ear into zones: lower, central and upper (20, 60 and 20 % of the ear length from the point of attachment of the ear to the stem, respectively), the values were 4.3 H, 5.65 N and 5.27 N.

Targeting Photosynthesis Under Abiotic Stress

Earth sustains life due to the presence of the photosynthesis process that produced food for other organisms on our planet. But rapidly changing climate of most of the continents results in losses to photosynthetic machinery that ultimately lead to threatening food security worldwide. The major limiting factor in plant growth is abiotic stresses which are thought to become more severe in near future also unabated increase in the world population the future potential yield of commercial crops is under serious threat. The global food demand is expected to double in the coming years. The reduction of photosynthetic capability of various crops due to various abiotic stresses factors like heat, salinity, drought, high light, and heavy metal are gathered to understand the mechanism of stress tolerance and wider adaptability of different crops. We highlight the impact of various abiotic stresses on the performance of the photosynthetic process in crop plants. Further, we reviewed the different new generation solutions for photosynthesis improvements include improving enzyme (Rubisco) kinetic properties, C4 pathway into C3 crops, reduce photorespiration, canopy architecture, light capture, and photosynthetic models approaches also we have reviewed the role of genetic engineering crops with improved photosynthesis process that withstand and provide significant yields under environmental stresses. A better understanding of the photosynthetic process under stress conditions could support the development of new crops with higher yield even under adverse environments.

Inovação em cultivares: panorama das proteções e registros da soja no Brasil

Technological innovations applied to seeds has been supported in Brazil. The establishment of legal mechanisms of intellectual protection and rules to commercialize plants and seeds were responsible for the growth of research and development of new crops. The soybean is the main crop produced in the past years in Brazil and, for this reason, the main goal of this research is to show the scenario of innovation technology of soybean seeds, highlighting the protection and records of crops in Brazil. The scope of our analysis reaches the period between 1998 to 2018.The questionnaire survey of quantitative approach and descriptive strategy was collected based on information from CultivarWeb database (in special from SNPC and RNC) from Ministério da Agricultura Pecuária e Abastecimento – MAPA (Ministry of Agriculture, Livestock and Supply). The secondary data were worked on Excel® Software by using descriptive statistics. The result of this questionnaire survey showed that EMBRAPA (Brazilian Agricultural Research Corporation) is the main public institution active in seed innovations and leader with the most important protection certifications and soybean crop records in Brazil. We also observed strong participation from foreign companies in this market, especially the ones that support the protection and record of transgenic soybean crops. We concluded that the number of records of soybean crop commercialization are higher than the protection certification.

Induced polyploidy and broad variation in phytochemical traits and altered gene expression in Salvia multicaulis

Induced polyploidy is nowadays an important strategy in plant breeding and for the development of new crops. Salvia multicaulis Vahl is a valuable medicinal plant that produce precious bioactive metabolites including triterpenic acids (TAs) and phenolic compounds. Hence, at first, for selecting elite lines, both HPLC and GC-MC analyses were performed on fourteen S. multicaulis lines. Then, seeds of selected lines of S. multicaulis were exposed to different concentrations (0.00, 0.05, 0.1, and 0.2 %) of colchicine for 24 or 48 h. The flow cytometric analysis and chromosome counting were used to confirm ploidy level of tetraploid control (2n = 4x = 28, 2C DNA = 1.36 pg) and hexaploid (2n = 6x = 42, 2C DNA = 1.97 pg) plants after seven-month. For the first time, the effects of in vitro polyploidization on morphological characteristics, TAs and phenolic acid contents as well as on the expression of six TAs biosynthesis related genes were investigated. The highest efficiency of hexaploidy (12.76 %) was achieved 48 h after exposure to 0.1 % colchicine concentration. The hexaploid plants showed different growth traits compared with those of tetraploid control plant; indeed, hexaploid plants had leaves with a darker green color, a lower trichome density, and lower plant height and root length. Moreover, there was a significant increase in rosmarinic acid and caffeic acid content in hexaploid plants compared with tetraploid control plants. Also, the increase of oleanolic acid (1.33 fold) content in hexaploids was associated with a significant increased expression of squalene synthase (SQS) and β-amyrin synthase (BAS) genes in hexaploid plants. Nevertheless, a significant decreased expression of squalene epoxidase (SQE), mixed-function amyrin synthase (MFAS), and lupeol synthase (LUS) was observed in hexaploid plants, that led to a reduced content of ursolic acid and betulinic acid compared with tetraploid control plants. These results confirmed that polyploidization is a breeding method with stochastic results in secondary metabolites production and gene expression related to biosynthetic pathways.

The Ubiquitin Switch in Plant Stress Response.

Ubiquitin is a 76 amino acid polypeptide common to all eukaryotic organisms. It functions as a post-translationally modifying mark covalently linked to a large cohort of yet poorly defined protein substrates. The resulting ubiquitylated proteins can rapidly change their activities, cellular localization, or turnover through the 26S proteasome if they are no longer needed or are abnormal. Such a selective modification is essential to many signal transduction pathways particularly in those related to stress responses by rapidly enhancing or quenching output. Hence, this modification system, the so-called ubiquitin-26S proteasome system (UPS), has caught the attention in the plant research community over the last two decades for its roles in plant abiotic and biotic stress responses. Through direct or indirect mediation of plant hormones, the UPS selectively degrades key components in stress signaling to either negatively or positively regulate plant response to a given stimulus. As a result, a tightly regulated signaling network has become of much interest over the years. The ever-increasing changes of the global climate require both the development of new crops to cope with rapid changing environment and new knowledge to survey the dynamics of ecosystem. This review examines how the ubiquitin can switch and tune plant stress response and poses potential avenues to further explore this system.

Do We Need New Crops for Arid Regions? A Review of Fruit Species Domestication in Israel

Climatic changes have created the imminent need for the development of new crops for arid regions. We started to domesticate and introduce wild and exotic fruit trees to our deserts in 1984. We tested different species in five eco zones in Israel, differing from each other in terms of maximum and minimum temperatures, type and degrees of salinities, water evaporation rates, rainfall, etc. We succeeded in cultivating pitaya species using hybrids from the Hylocereus and Selenicereus genera, and with a different species from the Cactaeae Cereus peruvianus, which we named Koubo. These two species are from the Cactaceae family, known for high water use efficiencies (WUE). We already have investors who started the semi-commercial production of Marula, Sclerocarya birrea sbsp. Caffra, and Argan—Argania spinosa. In spite of the fact that we developed good clones and knowledge of how to grow and ship White Sapote, Casimiroa edulis, and Indian jujube, Ziziphus mauritiana, we failed due to a lack of marketing research and development, which is essential for such a project. We have gene banks of some other new fruit crops waiting for investors to grow and bring them into the domestic and world markets.

EU Regulation of New Plant Breeding Technologies and their Possible Economic Implications for the EU and Beyond

New plant breeding technologies (NPBTs), including CRISPR gene editing, are being used widely, and they are driving the development of new crops. They are nevertheless a subject of criticism and discussion. According to a summer 2018 interpretation by the Court of Justice of the European Union (CJEU), European Union (EU) law makes most NPBTS subject to regulations governing the use of genetically modified organisms (GMOs) in the EU. The implications of this decision have been widely discussed in the literature, thereby stressing the importance of the decision for plant breeding and international trade within and beyond the EU. This contribution summarizes the status of the debate and highlights issues that have thus far not been considered—particularly with regard to the implications of EU regulations for NPBTs for countries outside the EU. We conclude that the practical implications of the CJEU decision reduce the EU’s comparative advantage and increase the cost of achieving the objectives of the European Green Deal. Our findings reveal an almost complete lack of possibilities for changing the current situation. China and countries oriented towards China are the most likely economic beneficiaries of the current situation.

EU Regulation of New Plant Breeding Technologies and Their Possible Economic Implications for the EU and Beyond

AbstractNew plant breeding technologies (NPBTs), including CRISPR gene editing, are being used widely, and they are driving the development of new crops. They are nevertheless a subject of criticism and discussion. According to a summer 2018 interpretation by the Court of Justice of the European Union (CJEU) applying an absolute interpretation of the precautionary principle, European Union (EU) law makes most NPBTs subject to regulations governing the use of genetically modified organisms (GMOs) in the EU. This contribution summarizes the status of the debate and highlights issues that have thus far not been considered—particularly with regard to the implications of EU regulations for NPBTs for countries outside the EU.

In vitro Ploidy Manipulation for Crop Improvement.

In vitro regeneration systems provide a powerful tool for manipulating ploidy to facilitate breeding and development of new crops. Polyploid induction can expand breeding opportunities, assist with the development of seedless triploid cultivars, enhance ornamental characteristics and environmental tolerances, increase biomass and restore fertility in wide hybrids. In vitro ploidy manipulation is commonly induced using antimitotic agents such as colchicine, oryzalin and trifluralin, while many other antimitotic agents have been relatively unexplored. Successful induction requires a synergistic pairing of efficient penetration of the antimitotic agent and may be dependent the length of exposure and concentrations of antimitotic agents, tissue types, and interactions with basal media and plant growth regulators. In vitro conditions vary among taxa and individual genera, species, and cultivars, often requiring unique treatments to maximize polyploid induction. In some taxa, the induction of polyploidy influences in vitro growth, development, and root formation. Here we provide an overview of mitotic inhibitors and their application for in vitro ploidy manipulation for plant breeding and crop improvement.

The quest for osmosensors in plants.

Osmotic stress has severe effects on crop productivity. Since climate change is predicted to exacerbate this problem, the development of new crops that are tolerant to osmotic stresses, especially drought and salinity stress, is required. However, only limited success has been achieved to date, primarily because of the lack of a clear understanding of the mechanisms that facilitate osmosensing. Here, we discuss the potential mechanisms of osmosensing in plants. We highlight the roles of proteins such as receptor-like kinases, which sense stress-induced cell wall damage, mechanosensitive calcium channels, which initiate a calcium-induced stress response, and phospholipase C, a membrane-bound enzyme that is integral to osmotic stress perception. We also discuss the roles of aquaporins and membrane-bound histidine kinases, which could potentially detect changes in extracellular osmolarity in plants, as they do in prokaryotes and lower eukaryotes. These putative osmosensors have the potential to serve as master regulators of the osmotic stress response in plants and could prove to be useful targets for the selection of osmotic stress-tolerant crops.

Maximum vs minimum harmonization: what to expect from the institutional and legal battles in the EU on gene editing technologies.

New plant‐breeding technologies (NPBTs), including gene editing, are widely used and drive the development of new crops. However, these new technologies are disputed, creating uncertainty in how their application for agricultural and food uses will be regulated. While in North America regulatory systems respond with a differentiated approach to NPBTs, the Court of Justice of the European Union (EU) has in effect made most if not all NPBT subject to the same regulatory regime as genetically modified organisms (GMOs). This paper discusses from a law and economics point of view different options that are available for the EU's multi‐level legal order. Using an ex‐ante regulation versus ex‐post liability framework allows the economic implications of different options to be addressed. The results show that under current conditions, some options are more expensive than others. The least costly option encompasses regulating new crops derived from NPBTs similar to those used in ‘conventional’ breeding. The current regulatory situation in the EU, namely making the use of NPBTs subject to the same conditions as GMOs, is the most costly option. © 2019 The Authors.

The importance and challenges of crop germplasm interdependence: the case of Bhutan

An analysis of food crop germplasm flows into and out of Bhutan was carried out to determine the extent of reliance of Bhutanese agriculture on introduced germplasm. Methods used included literature review, key informant interviews, field visits and crop pedigree analysis. Bhutan has been introducing foreign germplasm since the 1960s. By December 2015, about 300 varieties of 46 food crops including several non-traditional crops were introduced. Germplasm sources include CGIAR centres such as IRRI, CIMMYT, ICARDA, and AVRDC and countries such as Bangladesh, India, Japan, Korea, Nepal, and Thailand. Pedigree analysis of rice varieties indicated that 74% of the released varieties originated in other countries. Using imported germplasm, Bhutan has formally released over 180 varieties of cereals, fruits and vegetables. Initially, the germplasm flow was largely unregulated, but the country has been developing formal exchange mechanisms with the creation of the National Biodiversity Centre (NBC) in 1995. Findings point to a strong reliance on external germplasm for the country’s major food crops. International germplasm exchanges will remain important to deal with new environmental and climatic conditions and given the limited national plant breeding capacity. National agricultural policy should give higher priority to collaborative development of new crops in the Himalayan region and beyond.

Maintenance of meristem activity under stress: is there an interplay of RSS1-like proteins with the RBR pathway?

Plants have acquired rapid responses to a constantly changing environment. These adaptive and protective responses are the result of a complex signalling network regulating different aspects, ranging from ion homeostasis to cell cycle control. It is well established that stress inhibits cell division, which negatively impacts plant growth and development and hence results in biomass decrease and yield loss. Therefore understanding the link between stress perception and cell cycle control would allow development of new crops with increased productivity when subjected to stress. However, studies on cell cycle control under stress have been limited to well-known regulators of the cell cycle such as cyclins and stress-related phytohormone integrators. The recent discovery of RSS1, a novel intrinsically unstructured protein of rice, opened up new insights into how stress perception can be connected with cell cycle control in meristematic zones. Whereas RSS1 is well conserved among other plant lineages, eudicots present proteins sharing little sequence homology with RSS1. Here, we discuss how RSS1-like proteins might also be functional in dicots, and possibly act through the retinoblastoma-related pathway to regulate both S-phase transition and cell fate in meristems.

Age-related changes in nitrogen resorption and use efficiency in the perennial new crop Physaria mendocina (Brassicaceae)

Domestication of desert-adapted species and their development into perennial crops has been proposed as an alternative to increase cropping intensity in arid lands, while reducing nitrogen inputs and losses. Among traits involved in nitrogen conservation much attention has been drawn to resorption patterns. However, understanding of intra-population variability in resorption and nitrogen use efficiency is required prior to the development of new crops. Here we evaluate age-related changes in resorption patterns and nitrogen use efficiency (NUE) within a wild population of Physaria mendocina (Brassicaceae). We generated a relative age index, based on morphological traits, and we use it as an independent variable to regress nitrogen concentrations in roots and leaves (green and senesced), nitrogen resorption efficiency and use efficiency. Nitrogen in green and senesced leaves decrease with age, resorption efficiency did not change, and nitrogen use efficiency increased. The lower nitrogen concentration in green leaves and higher proficiency (lower nitrogen concentrations in senesced leaves) of older plants might be due to a decrease in acquisition capacity. Constant efficiency is explained by the lack of differences in concentration in green and senesced leaves slopes. Higher proficiency in older plants resulted in higher NUE; this relationship would be modulated by nitrogen concentration in green leaves, which, in turn, is controlled by nitrogen availability and acquisition. These findings have implications in the domestication process, since in perennial species biomass production and internal plant nitrogen turnover over multiple seasons, are central key to physiological functions such as plant re-growth and winter survival. We identified a few questions as directions for future research.

Integrated sensing of soil moisture at the field-scale: Measuring, modeling and sharing for improved agricultural decision support

Determining the best way to efficiently use limited water resources, for food and energy-dedicated crops, has become crucial due to the rise in extreme events (floods/droughts) and higher variability in rainfall attributed to global climate change. Changing climate conditions will require new crops to be adapted to a changing agricultural environment. Reliable information on seasonal trends in crop growth and evapotranspiration with associated uncertainty/confidence ranges is crucial to guide the development of new crops and management strategies to cope with future climate. Given that crop growth is strongly coupled to soil moisture, developing reliable growth curves requires a detailed understanding of soil moisture at the field-scale. Typically, it is impractical to collect soil samples to adequately assess soil moisture that represents both spatial distribution at the field-scale and temporal dynamics on the scale of a growing season (e.g. 110days for cereals). A novel way to address soil moisture monitoring challenges is through an integrated, agro-ecosystems-level approach using an integrated sensing system that can link data from multiple platforms (wireless sensors, satellites, airborne imagery, near real-time climate stations). Assimilated data can, then, be fed into predictive models to generate reference crop growth curves and predict regionally-specific yield potentials. However, integrated sensing requires interagency cooperation, common data processing standards and long-term, timely access to data. Large databases need to be reusable by various organizations and accessible, in the future, with comprehensive metadata. During the 2012 growing season a feasibility study was conducted which involved measuring field-scale soil moisture with sensor network technology. The experiment utilized radially-distributed sensors for tracking in-season soil moisture. OpenGIS-compliant services and standards were utilized to provide long-term access to sensor data and construct corresponding metadata. Sensor Model Language, an inter-operable metadata format, was used to create documentation for the sensor system and sensing components. Two different third party implementations of the Sensor Observation Service were tested for providing long-term access to the data. This work discusses a set of key recommendations for monitoring field-scale soil moisture dynamics for integration with remote sensing and models, including: (1) Improved in situ sensing technology that would allow for less restrictive soil moisture measurements. (2) Integration of field-scale in situ networks with regional remote sensing monitoring. (3) The development of software and web services to integrate data from multiple sources with models for decision support.

Plant-virus interactions and the agro-ecological interface

As a result of human activities, an ever-increasing portion of Earth’s natural landscapes now lie adjacent to agricultural lands. This border between wild and agricultural communities represents an agro-ecological interface, which may be populated with crop plants, weeds of crop systems, and non-crop plants that vary from exotic to native in origin. Plant viruses are important components of the agro-ecological interface because of their ubiquity, dispersal by arthropod vectors, and ability to colonize both crop and wild species. Here we provide an overview of research on plant-virus dynamics across this interface and suggest three research priorities: (1) an increased effort to identify and describe plant virus diversity and distribution in its entirety across agricultural and ecological boundaries; (2) multi-scale studies of virus transmission to develop predictive power in estimating virus propagation across landscapes; and (3) quantitative evaluation of the influence of viruses on plant fitness and populations in environmental contexts beyond crop fields. We close by emphasizing that agro-ecological interfaces are dynamic, influenced by the human-mediated redistribution of plants, vectors, and viruses around the world, climate change, and the development of new crops. Consideration of virus interactions within these environmentally complex systems promises new insight into virus, plant, and vector dynamics from molecular mechanisms to ecological consequences.

Generation of an artificial ring chromosome in Arabidopsis by Cre/LoxP‐mediated recombination

A eukaryotic chromosome consists of a centromere, two telomeres and a number of replication origins, and 'artificial chromosomes' may be created in yeast and mammals when these three elements are artificially joined and introduced into cells. Plant artificial chromosomes (PACs) have been suggested as new vectors for the development of new crops and as tools for basic research on chromosomes. However, indisputable PAC formation has not yet been confirmed. Here, we present a method for generating PACs in the model plant Arabidopsis thaliana using the Cre/LoxP and Activator/Dissociation element systems. The successfully generated PAC, designated AtARC1 (A.thaliana artificial ring chromosome1), originated from a centromeric edge of the long arm of chromosome2, but its size (2.85Mb) is much smaller than that of the original chromosome (26.3Mb). Although AtARC1 contains only a short centromere domain consisting of 180bp repeats approximately 250kb in length, compared with the 3Mb domain on the original chromosome2, centromere-specific histone H3 (HTR12) was detected on the centromeric region. This result supported the observed stability of the PAC during mitosis in the absence of selection, and transmission of the PAC to the next generation through meiosis. Because AtARC1 contains a unique LoxP site driven by the CaMV 35S promoter, it is possible to introduce a selectable marker and desired transgenes into AtARC1 at the LoxP site using Cre recombinase. Therefore, AtARC1 meets the criteria for a PAC and is a promising vector.

The potential of South African indigenous plants for the international cut flower trade

A broad review is presented of recent developments in the commercialization of southern Africa indigenous flora for the cut flower trade, including potted flowers and foliages (“greens”). The botany, horticultural traits and potential for commercialization of several indigenous plants have been reported in several publications. The contribution of species indigenous and/or endemic to southern Africa in the development of cut flower crop plants is widely acknowledged. These include what is known in the trade as gladiolus, freesia, gerbera, ornithogalum, clivia, agapanthus, strelitzia, plumbago and protea. Despite the wealth of South African flower bulb species, relatively few have become commercially important in the international bulb industry. Trade figures on the international markets also reflect the importance of a few species of southern African origin. The development of new research tools are contributing to the commercialization of South African plants, although propagation, cultivation and post-harvest handling need to be improved. A list of commercially relevant southern African cut flowers (including those used for fresh flowers, dried flowers, foliage and potted flowers) is presented, together with a subjective evaluation of several genera and species with perceived potential for the development of new crops for the florist trade. It is concluded that research should be focused on potential markets rather than on preconceived product concepts. A special national effort is required to maximize the opportunities presented by the rich diversity of the flora and to develop an internationally competitive cut flower industry.

US effort in the development of new crops (Lesquerella, Pennycress Coriander and Cuphea)

The US effort for the development of new crops is directed toward the advancement of crops that can be grown in rotation with traditional commodity crops, off-season production and utilization of acreage not currently under cultivation. This effort is intended to have no or minimal impact on crop rotations that are sources for food production. The high oil content and the fatty acid profiles of mustard crops make them suitable for utilization as both fuels and base stocks for functionalized industrial chemicals. Pennycress (thlaspi arvense) and lesquerella (lesquerella fendleri) are representatives of this family and have received much attention due to their potential to grow over winter in rotation with soybean production throughout the Midwest (pennycress) or as a winter annual in the desert southwest (lesquerella). Pennycress is an oilseed crop that produces 36% oil with a wide distribution of fatty acids (principal fatty acid is erucic acid 37%) that make it suitable for production of biodiesel. The key aspect of pennycress is that its lifecycle is complete such that a full season soybean can follow its production in the same growing season. Lesquerella is an oilseed crop containing 30% oil that is composed of 60% hydroxy fatty acids. Hydroxy fatty acids are used in a wide range of industrial and cosmetic applications. Two other New Crops currently under investigation are cuphea and coriander. Cuphea is an oilseed crop that contains 35% oil that is composed of medium chain saturated fatty acids. The current cuphea variety under investigation is high in capric fatty acid (76%) with other cuphea species producing high levels of lauric acid. Cuphea can be grown throughout the Midwest but suffers from several agronomic traits that are currently limiting is potential adaptation. Coriander is also an oilseed crop with 25% oil where the main fatty acid is petroselinic acid (76%). Coriander can be grown under a short season production and has potential to rotate as a second crop following winter wheat. Petroselinic acid can be ozonolytically cleaved into adipic and lauric acids both high volume industrial chemicals.
