Bioactives in Berry Fruits with Emphasis on In Vitro Bioaccessibility for Human Nutrition

This study aimed to investigate the bioaccessibility and biostability of carotenoids, vitamin E isomers, and individual polyphenolic compounds after the in vitro gastrointestinal digestion of two types of berries (raspberry and blackberry fruits). The results of the polyphenols analysis showed that raspberry fruits contained higher concentrations of hydroxybenzoic acids, hydroxycinnamic acids, flavanols, and flavonols compared to blackberry fruits, but exhibited the lowest bioaccessibility values for all the studied polyphenol classes. Ellagic acid represented 13.63% and 2.65% of the hydroxybenzoic acids in raspberry and blackberry fruits. The hydroxybenzoic acids exhibited the highest bioaccessibility index in the intestinal phase of both types of berries, and gallic acid emerged as one of the most bioaccessible phenolic compounds. The bioaccessibility of carotenoids ranged between 15.7 and 17.30% for lutein, 5.52 and 7.56% for astaxanthin, and 7.85 and 9.93% for canthaxanthin, with elevated values being observed in raspberry fruits. Although vitamin E and carotenoids follow a similar path for absorption, the bioaccessibility of vitamin E isomers was higher than that of carotenoids, with γ-tocopherol being the most bioaccessible isomer in both raspberries and blackberries. Knowing the bioaccessibility of food constituents during digestion is crucial, as the potential effectiveness of bioactives for human health largely depends on the bioavailability of these molecules.

Comprehensive structural analysis of anthocyanins in blue honeysuckle (Lonicera caerulea L.), bilberry (Vaccinium uliginosum L.), cranberry (Vaccinium macrocarpon Ait.), and antioxidant capacity comparison

The objectives of this research were to analyze anthocyanins in blue honeysuckle (Lonicera caerulea L.), bilberry (Vaccinium vitis-idaea L), and cranberry (Vaccinium macrocarpon Ait.), using HPLC-ESI-QTOF-MS2, Fourteen, fifteen, and eight anthocyanins were identified in blue honeysuckle, bilberry, and cranberry, respectively. Cyanidin-3-glucoside (C3G) and peonidin-3-glucoside were detected in all three types of berries, with blue honeysuckle showing the highest C3G content at 5686.28 mg/100 g DW. Total phenolic content (TPC) and total flavonoid content (TFC), along with ABTS, DPPH, and FRAP assays, were measured. Blue honeysuckle exhibited the highest levels of TPC and TFC. The SOD, POD, and CAT activities in blue honeysuckle were 1761.17 U/g, 45,525.65 U/g, and 1043.24 U/g, respectively, which were significantly superior to those in bilberry and cranberry. The antioxidant mechanisms of these enzymes were investigated by molecular docking, C3G showed a higher affinity for POD, confirming the effectiveness of C3G as an antioxidant.

Resveratrol: A Potential Active Compound for Inflammatory Bowel Disease

Inflammatory Bowel Disease (IBD) is a chronic intestinal disorder consisting of Crohn’s Disease (CD) and Ulcerative Colitis (UC). The highest prevalence of IBD is found in Asia and the cases often occur in the 15-35 group of age. Conventional therapy options that are commonly used have some side effects that impact IBD patients. Therefore, it is necessary to look for new strategies in order to treat IBD regarding their effectiveness, affordability and achieving minimum side effects. Resveratrol, a natural non-flavonoid polyphenolic compound, is commonly found in grapes and various types of berries. It is known to potentially overcome inflammation in IBD through various mechanisms including acting as anti-inflammatory, antioxidant, immunomodulatory effects, and its ability to influence the gut microbiota. This study is aiming for explaining and reviewing further mainly on resveratrol’s extraction method and its mechanism of actions to improve IBD. The resources for this study are done by searching through PubMed, ProQuest, ScienceDirect, MDPI, and Google Scholar with keywords (Inflammatory Bowel Disease) AND (Resveratrol), ⁠(Incidence and Prevalence) of Inflammatory Bowel Disease across Asia, (Threat) AND (Therapy) AND (Inflammatory Bowel Disease), (Bioactive) AND (Therapy) AND (Inflammatory Bowel Disease), (Extraction) AND (Method) AND (Resveratrol), and (Pathophysiology) AND (Inflammatory Bowel Disease). Based on evidence found on resveratrol’s benefits, this compound is apparently promising to alternatively treat IBD, but still needs more research to support its effectiveness.

Aroma profiling analysis of grape berries based on electronic nose detection

Aroma analysis of grape berries can provide support for the breeding of new varieties and increase economic value. In order to preliminarily explore and screen the berry aroma characteristics of 191 grape germplasm resources, the electronic nose detection method was used to analyze the berry aroma characteristics. The clustering results of 10 sensors showed that the aroma types of grape berries could be identified. The first category (I) contains 139 germplasm; The second group (II) contains 32 germplasms; The third group (III) contains four germplasms; The fourth group (IV) and the fifth group (V)include 8 germplasm. The berry aroma of cluster I, II, IV and V was significantly different from that of cluster III, mainly manifested by the significant difference in the response values of W1S (methane), W2S (alcohols) and W5S (nitrogen oxides). The W1S, W2S and W5S sensors, as well as the W2W (aromatic components and organic sulfides) aroma sensors show high response values for 'Ayaneskeal' and 'Urbana', indicating a strong aroma. The results of this study preliminarily elucidates the aroma differences among different grape germplasms, providing a data basis for the selection of grape germplasms with distinct aroma, which will be used as a source to obtain new varieties with aromatic value for the production of grapes for fresh consumption and beverages, such as wine. It also provided data basis for the establishment of grape germplasm resource bank.

Host Range of Phytophthora spp. from Berry Crops in Huelva, Spain.

Crop declines have been observed in raspberry and blueberry farms in the southwest region of Spain, which is the most important berry-producing area in the country. This study aimed to identify and characterize the pathogens associated with these diseases using molecular and morphological methods. Additionally, pathogenicity tests were performed on different raspberry, blueberry, and strawberry cultivars to determine possible susceptible hosts in the area. An isolate of Phytophthora cactorum was obtained from a symptomatic strawberry plant, an isolate of P. cinnamomi was obtained from a symptomatic blueberry plant, and isolates identified as P. rosacearum, P. rubi, and a previously unknown species named P. balkanensis were recovered from symptomatic raspberry plants. Results from the pathogenicity tests reported, for the first time, P. rubi causing root rot and wilting complex in Spanish raspberry crops. Additionally, P. cinnamomi was found to affect highbush blueberry production in Spain. Thus, this study provides valuable insights into the identification and characterization of Phytophthora spp. associated with the decline of blueberry and raspberry crops in Huelva. It also provides essential recommendations regarding the potential risks associated with the use of other types of berries as rotational crops and emphasizes the necessity for effective management strategies to mitigate crop losses. This is particularly critical given the limited soil disinfection alternatives available in Spain.

Cerebral Aneurysm Characteristics and Surgical Outcomes: An In-Depth Analysis of 346 Cases Operated Using Microsurgical Clipping.

This comprehensive study analyzes 346 surgically treated intracranial aneurysms, emphasizing the importance of understanding risk factors and prevalent characteristics in patients. Intracranial aneurysms, primarily of the saccular or berry type, significantly contribute to nontraumatic subarachnoid hemorrhages and demonstrate a rising incidence due to advances in imaging techniques. The study highlights a gender discrepancy in aneurysm occurrence and a higher prevalence in individuals over 30 years old. The research delves into various aspects, including aneurysm localization, diameter, neck dimensions, and rupture status, with a focus on the anterior communicating artery and middle communicating artery as predominant locations. Significant findings include the prevalence of ruptured aneurysms and the impact of arterial hypertension, atherosclerosis, obesity, and diabetes on aneurysm epidemiology. The study also investigates the occurrence of vasospasm, a significant factor in delayed morbidity and mortality in aneurysmal subarachnoid hemorrhage. The utilization of the Glasgow Outcome Scale and other quantification scales aids in understanding the severity and postoperative outcomes of intracranial aneurysms. Challenges such as the incidence of reopenings and postoperative osteomyelitis are addressed, underlining the need for refined protocols and multidisciplinary approaches in treatment. The study's results contribute to the existing knowledge base on intracranial aneurysms, emphasizing the importance of ongoing research and tailored treatment strategies. The comprehensive nature of this analysis, covering preoperative, intraoperative, and postoperative factors, provides valuable insights into the complex interplay of risk factors and clinical outcomes in patients with intracranial aneurysms.

Meta-analysis of the prevalence of norovirus and hepatitis a virus in berries

Norovirus (NoV) and hepatitis A virus (HAV) stand as the predominant agents associated with viral foodborne infections. Outbreaks have been documented to be caused by various types of food items, including fresh and/or frozen berries. Comprehensive data concerning crucial viral pathogens in berries remain limited and are not currently available in aggregate form. Consequently, the present study aimed to compile the existing information regarding the prevalence of NoV and HAV in this matrix. Records of foodborne viruses were systematically extracted from database repositories up to December 2022, adhering to PRISMA standards and were subjected to a multilevel random effect meta-analysis model to determine the mean occurrence rate of NoV and HAV. A high heterogeneity across studies was observed (I2 = 82 %), reflecting variations in the prevalence of sampling locations, years, berry types, and sample conditions, among other potential contributing factors. The prevalence of NoV and HAV in berries was calculated at 2.12 % (95 % CI 1.74–2.59 %), and no statistically differences were observed among the viral types or genogroup categories. However, it is important to clarify that this estimate should be taken with caution given the high heterogeneity. There was no discernible correlation between viral prevalence and any particular berry type. However, there was a temporal correlation observed with the year of sampling, revealing a significantly decreasing trend throughout the study period. A significant influence of the sample condition (fresh or frozen) was observed in relation to the prevalence of NoV GII and HAV. Overall higher viral prevalences were identified in berries originating from African countries as compared to those sourced from other continents. It was also noted that the prevalence of NoV GI was significantly higher in samples collected directly from farms compared to those obtained from retailers. The outcomes of this comprehensive meta-analysis propose that while viral contamination of berries is diminishing in more recent times, the prevalence remains substantial in certain African countries, having a significant risk for foodborne infections. It is imperative to implement intervention strategies in these regions to enhance product safety.

Consumption of Berries and Flavonoids in Relation to Mortality in NHANES, 1999–2014

BackgroundBerries are foods that are abundant in nutrients, especially flavonoids, that promote good health; however, the effects of total berries on mortality are not well characterized. ObjectivesWe evaluated whether intakes of total berries and specific berry types including blueberries, strawberries, cranberries, flavonoids, and subclasses of flavonoids (anthocyanidins, flavonols, flavones, flavanones, flavan-3-ols, and isoflavones) in relation to mortality risk in United States adults. MethodsA nationally representative sample of the United States adult population was obtained using data from the 1994–2014 NHANES (n = 37,232). Intake of berries was estimated using 24-h food recalls (1999–2014), and flavonoids intake was calculated using the matched USDA’s expanded flavonoid database. Mortality outcomes based on 8 y of follow-up were obtained using linked death certificates. ResultsCompared with nonconsumers, the multivariable-adjusted hazard ratio for all-cause mortality was 0.79 [95% confidence intervals (CI): 0.7, 0.89] for any berry consumption, 0.86 (0.75, 0.99) for strawberry consumption 0.79 (0.66, 0.95) for blueberries, and 0.69 (0.51, 0.93) for cranberries. Compared with the lower median of intake, risk of all-cause mortality for greater intake was 0.85 (0.74, 0.97) for total flavonoids, 0.85 (0.76, 0.95) for anthocyanidins, 0.9 (0.82, 0.99) for flavan-3-ols, 0.89 (0.79, 0.9) for flavanols, and 0.89 (0.8, 0.99) for flavones. There was a dose–response relationship between intakes of total flavonoids, anthocyanidins, and flavones and lower all-cause mortality risks (Ptrend < 0.05). Risk for cardiometabolic mortality was 0.75 (0.58, 0.98) for berry consumers and 0.49 (0.25, 0.98) for cranberry consumers. For respiratory disease mortality, risk was 0.41 (0.2, 0.86), compared with blueberry nonconsumers. ConclusionHigher intakes of berries and flavonoids were associated with a lower overall mortality risk in adult Americans. Few adults regularly consume berries, indicating that increased intake of berries and flavonoid-rich foods may be beneficial to health.

Social Significance of Food Forest Resources for Residents of the Sakha Republic (Yakutia)

This article analyzes the results of a sociological study conducted among residents of the Sakha Republic (Yakutia). The study focused on gathering wild berries and their beneficial properties. The respondents noted that they mainly collect such types of wild berries as lingonberries, red currants, and blueberries.

The study highlights the importance of wild berries in the daily life of the local population, their role in ensuring food security and maintaining health. The survey revealed the main types of berries harvested in the forest, as well as their useful properties. Thus, the article is a sociological study aimed at studying the importance of wild berries for the local population and their perception of the beneficial properties of forest resources. The results of the study can be used to develop strategies for the conservation and sustainable use of forest resources, as well as to raise awareness of the local population about their importance. In general, this work is a sociological analysis of the importance of wild berries in the life of the population of Yakutia and their awareness of the beneficial properties of these resources. The data obtained can be used to develop strategies for the conservation and sustainable use of forest resources, as well as to raise awareness of the local population about their value.

Berry Consumption and Sleep in the Adult US General Population: Results from the National Health and Nutrition Examination Survey 2005-2018.

Poor sleep is associated with numerous adverse health outcomes. Berries are rich in micronutrients and antioxidants that may improve sleep quality and duration. We determined the association of berry consumption and sleep duration and sleep difficulty among adult participants in NHANES. We analyzed the diet of US adults aged ≥ 20 y using two non-consecutive 24 h recalls from the National Health and Nutrition Examination Survey 2005 to 2018 (N = 29,217). Poor sleep quality was measured by sleep duration (short sleep duration: <7 h), long sleep (≥9 h), and reported sleep difficulty. The relative risk of poor sleep outcomes for berry consumers vs. nonconsumers was modelled using population weight-adjusted multivariable general logistic regression. About 46% of participants reported inadequate sleep duration, and 27% reported sleep difficulties. Twenty-two percent reported consuming berries. Berry consumers had a 10-17% decreased risk of short sleep. The findings were consistent for specific berry types including strawberries and blueberries (p < 0.05). No significant associations with long sleep were found for total berries and any berry types. A decreased risk of sleep difficulties was found to be linked to blackberry consumption (adjusted OR = 0.63, 95% CI: 0.40-0.97; p = 0.036) but not for other berries. US adult berry consumers had a decreased risk of reporting short sleep compared to nonconsumers. Berries are underconsumed foods in the US adult population, and increased berry consumption may improve sleep quality.

Obtaining preparations with increased content of bioactive compounds from eight types of berries

BACKGROUND: Cranberries, black and red currants, strawberries, chokeberries, raspberries, blueberries and blackberries, due to the high content of polyphenolic compounds, become an excellent matrix for the production of preparations that can be used as nutraceuticals. OBJECTIVE: Evaluation of the content of bioactive compounds and health-promoting activity of preparations from polyphenolic fractions isolated from eight types of berries. METHODS: The preparations were obtained by lyophilization of the polyphenolic fraction of fruit extracts, and then they were evaluated in terms of physicochemical properties, content of polyphenolic compounds and antioxidant, antidiabetic, antiobesity and anticancer activity. RESULTS: The analyzes showed a very diverse content of bioactive compounds and a high health-promoting potential significantly depending on the type of fruit. In total, 61 polyphenolic compounds were identified, with anthocyanins being the dominant group. A positive correlation was found between the content of polyphenolic compounds and high antioxidant activity. A cytotoxic effect on colorectal adenocarcinoma cells (Caco-2) was also found. In addition, all the obtained preparations turned out to be effective inhibitors of enzymes promoting diabetes and obesity. CONCLUSIONS: The obtained preparations can be used in the production of nutraceuticals or functional food additives, applicable in the prevention and treatment of lifestyle diseases.

Effects of Freeze-Drying on Sensory Characteristics and Nutrient Composition in Black Currant and Sea Buckthorn Berries

Fresh berries contain numerous components that can undergo complex changes during the drying process. This study aims to investigate the effect of freeze-drying on the sensory and chemical properties of black currant and sea buckthorn berries. Freeze-drying was performed at a shelf temperature of 35–55 °C with a step of 5 °C and durations of 18, 20, 22, and 24 h. Comparing the final freeze-dried berries with their fresh counterparts, it was observed that at a shelf temperature of 50 °C and a drying time of 18 to 20 h, there was a minimal loss in the content of vitamins, organic acids, and carbohydrates. However, based on organoleptic evaluations, the best results were achieved after drying for 20 h. Furthermore, the preservation of citric and malic acids in black currant berries, along with citric, tartaric acids, and sucrose in sea buckthorn berries, was only at 45.6% when the freeze-drying time was extended to 22 h. Considering the physical and chemical properties of listed freeze-dried berries, the optimal parameters were identified as a shelf temperature of 50 °C and a drying time of 20 h. The findings from this study serve as a foundation for selecting appropriate freeze-drying parameters for various types of berries.

Characterization of the Toxigenic Potential of Bacillus cereus sensu lato Isolated from Raw Berries and Their Products.

Bacillus cereus is estimated to be responsible for 1.4-12% of all food poisoning outbreaks worldwide. The objective of this study was to investigate the toxigenic potential of 181 isolates of B. cereus previously recovered from different types of berries and berry products (strawberries, raspberries, blackberries, and blueberries) by assessing the presence of enterotoxin genes (hblA, hblC, hblD, nheA, nheB, nheC, and cytK) and an emetic toxin cereulide synthetase gene (ces). The cytotoxic activity on Caco-2 cells was also evaluated for the two isolates containing the gene cytK. Twenty-three toxigenic profiles were found. The nheABC (91.7%) and hblACD (89.0%) complexes were the most prevalent among the isolates, while the cytK and ces genes were detected in low percentages, 1.1% and 3.3%, respectively. In addition, the nheABC/hblACD complex and ces genes were detected in isolates recovered throughout the production process of blackberries and strawberries. The cytotoxic activity on Caco-2 cells was also observed to be greater than 60% for isolates containing the cytK gene.

Rapid determination of the storage time of cold-pressed berry seed oils using flash gas chromatography E-Nose coupled with chemometrics

Since oils containing a high content of polyunsaturated fatty acids are susceptible to oxidation, it is necessary to monitor the degree of deterioration during storage, e.g. by measuring the volatile compounds. This study aimed to assess volatile profiles of berry seed oils in terms of the authenticity and the deterioration assessment using flash gas chromatography (FGC E-Nose) combined with chemometrics. Berry seed oils (raspberry, blackcurrant, strawberry, chokeberry), obtained from three different suppliers and stored for a one year in brown bottles at room temperature, were analysed after 0, 3, 6, 9 and 12 months of storage. Principal component analysis enabled separation of oil samples by different berry types, suppliers and storage times. To predict the storage time, partial least square (PLS) models were built for each type of berry oil. Determination coefficients (R2) in cross-validation ranged from 0.842 (RMSECV = 1.69 months) to 0.969 (RMSECV = 0.75 months). Selecting the specific regions of chromatograms improved the residual prediction deviation (RPD) to values between 2.8 and 5.7, which indicated the suitability of the PLS models to predict the storage time in the quality control of berry oils.

Survival and nutritional requirements for overwintering Drosophila suzukii (Diptera: Drosophilidae) in Kentucky.

The ability to cope with novel climates is a key determinant of an invasive species' success. Drosophila suzukii (Matsumura, 1931) is an invasive fruit pest, and its seasonality varies across its range. Current evidence suggests that D. suzukii occurs year-round in warmer climates but has low overwintering survival in colder climates and relies on refuges or reinvades each spring. Here, we assessed the capacity of D. suzukii ability to overwinter in Kentucky, a temperate mid-latitude state with relatively mild but variable winters. We tracked year-round population changes for 3 yr and observed the highest populations in early winter months. Following an annual population crash in winter, small numbers of flies remained through the late winter and spring. We also conducted outdoor cage studies to determine the extent to which food resources and microhabitat impact survival and postwinter fecundity under natural conditions. Flies with no food had poor survival during the warmest periods of winter, and flies in all treatments had lower survival in the coldest month. Provisioning flies with either artificial diet or wild berries improved survival. As a follow-up, we determined whether D. suzukii could survive and reproduce after long-term exposure to a typical winter temperature on various wild berries. Drosophila suzukii had the highest survival on privet (Ligustrum sp.), but all berry types yielded higher survival than flies without food. Our results suggest that noncrop berries play an important role for overwintering D. suzukii, and as winters warm the availability of wild berries could influence early-season populations.

Detection of Hepatitis A RNA, Hepatitis E RNA, Human Adenovirus F DNA, and Norovirus RNA in Fresh and Frozen Berry Products at Point of Retail in Ireland.

Soft fruits are at particular risk of contamination with enteric viruses such as Hepatitis A virus (HAV), Hepatitis E Virus (HEV), Norovirus (NoV), Human Adenovirus (HAdV) and Sapovirus (SaV). The aim of this study was to investigate, for the first time, the presence of these biological agents in ready to eat (RTE) berries at point of retail in Ireland. A sampling strategy was designed in which RTE fresh and frozen strawberries and raspberries were purchased from five retailers between May and October 2018. Reverse Transcriptase Polymerase Chain Reaction (RT-qPCR) assays for HEV RNA, Nov RNA, SaV RNA, and human Adenovirus species F DNA (HAdV-F) were performed on 239 samples (25g portions). Viral nucleic acid was present in 6.7% (n = 16) of samples tested as follows: HAV RNA (n = 5), HAdV-F DNA (n = 5), HEV RNA (n = 3) and NoV GII RNA (n = 3). Sapovirus RNA was not detected in any product. No significant differences were found between berry type, fresh/frozen status, or supermarket source. This study suggests a risk that exists across all retail outlets however only low levels of nucleic acid ranging from 0 to 16 genome copies/g were present. Although these findings may reflect non-viable/non-infectious virus the continued provision of risk mitigation advice to consumers is warranted and further work is required to ensure control measures to reduce contamination are implemented and enforced.

The pericarp structure and histogenesis in Enkianthus: on the ancestral fruit type in Ericaceae family

Abstract According to modern phylogenetic data, the monotypic subfamily Enkianthoideae is sister to all other subfamilies of the family Ericaceae s.l. Aiming to determine the peculiarities of development and structure of Enkianthus pericarp and to reveal the principal characters of its structure, which can be original for the Ericaceae, we have studied fruit anatomical structure at different stages of development in four species of the genus Enkianthus belonging to three sections: Meisteria, Enkiantella, Enkianthus. The pericarp of superior loculicidal capsule of Enkianthus is differentiated into three histogenetic zones: (i) one-layered exocarp, (ii) multilayered mesocarp differentiated into two histological zones: the peripheral parenchymatous one, and the inner sclerenchymatous one, and (iii) one-layered endocarp composed of tangentially elongated sclereids. It has been shown that the lignification of cells of the endocarp proceeds after the lignification of the inner zone of the mesocarp. Our investigation demonstrates that the superior loculicidal capsules of Enkianthus are capsules of Hamamelis type, which are recognized as the probable ancestral (plesiomorphic) fruit type for other subfamilies of Ericaceae. This fruit type is recognized as the original in several modes of morphogenetic transformations of fruit in Ericaceae family, from which other types of capsules, pyrenariums, and berries originated.

Biomarkers of Berry Intake: Systematic Review Update.

Berries are rich in (poly)phenols, and these compounds may be beneficial to human health. Estimating berry consumption through self-reported questionnaires has been challenging due to compliance issues and a lack of precision. Estimation via food-derived biomarkers in biofluids was proposed as a complementary alternative. We aimed to review and update the existing evidence on biomarkers of intake for six different types of berries. A systematic literature search was performed to update a previous systematic review on PubMed, Web of Science, and Scopus from January 2020 until December 2022. Out of 42 papers, only 18 studies were eligible. A multimetabolite panel is suggested for blueberry and cranberry intake. Proposed biomarkers for blueberries include hippuric acid and malvidin glycosides. For cranberries, suggested biomarkers are glycosides of peonidin and cyanidin together with sulfate and glucuronide conjugates of phenyl-γ-valerolactone derivatives. No new metabolite candidates have been found for raspberries, strawberries, blackcurrants, and blackberries. Further studies are encouraged to validate these multimetabolite panels for improving the estimation of berry consumption.

Development of the method for calculating and analytical accounting of the production of berry crop products

The article deals with the issues of organization and features of the technology for the production of berry crops. The organizational and methodological aspects of calculating the cost of production of berry crops are critically assessed. Recommendations have been developed to improve the calculation of the cost of production of berry crops of various varieties by distributing production costs for high-quality types of berries in proportion to the content of sugar and other quality elements in them. Recommendations are proposed for rationalizing and detailing the analytical accounting of costs for the production of berry crops by using subanalytic accounts (subconto) by type and analytical accounts by berry crop varieties.
