Genome-wide identification of the MATE gene family and functional characterization of PbrMATE9 related to anthocyanin in pear

Plant multidrug and toxic compound extrusion (MATE) genes play an important role in the process of detoxification, plant morphogenesis, and anthocyanin accumulation. However, whether the MATE gene family functions in pear peel coloration is still unknown. To evaluate and identify the MATE gene family members which are involving in anthocyanin accumulation and coloration in pear. In this study, 85 MATE genes were identified in the reference pear genome of ‘Dangshansuli’ through genome-wide identification. Based on gene structure and phylogenetic tree analysis, the MATE family was divided into five subfamilies. RNA sequencing and quantitative real-time polymerase chain reaction (qRT-PCR) indicated that the expression patterns of PbrMATEs were tissue-specific. 28.24% (24) of PbrMATE genes were expressed in the fruits, and 44.71% (38) of PbrMATE genes were expressed in the leaves. Additionally, we found that the expression levels of PbrMATE9, PbrMATE26, PbrMATE50, and PbrMATE69 in debagged fruits with red peel were significantly higher than those in bagged fruits without red peel, according to our bagging/debagging treatment of ‘Mantianhong’. The expression pattern of PbrMATE9 was consistent with the variation trend in anthocyanin content, suggesting that it might play an important role in anthocyanin accumulation in response to light exposure. Subcellular localization showed that PbrMATE9 was a membrane protein. More strikingly, the transient overexpression of PbrMATE9 promoted anthocyanin accumulation in the peel of pear, and the expression of structural genes (PbrCHI, PbrANS, PbrDFR, and PbrUFGT) in the anthocyanin biosynthesis pathway also increased significantly. Through co-expression network analysis, the transcription factors were identified, such as WRKY, COL, GATA, and BBX, which might be involved in the regulation of PbrMATE9. The study has enriched the genetic resources and improved the understanding of the regulation network of anthocyanin accumulation in pear.

THE INFLUENCE OF PRE-HARVEST TREATMENTS ON FRUITS QUALITY OF APPLE CULTIVARS (MALUS DOMESTICA BORKH.)

Apples fruit quality is mainly influenced by biotic and abiotic factors. Various possible pomological approaches are able to improve fruit quality and market value. Among these, techniques of fruit bagging and summer pruning have become an integral part of pomological practises in many countries, because it is a safe and eco-friendly technique to protect fruits from multiple stresses, preserving or improving the overall quality. The bagging consists essentially of enclosing a young fruit in a cardboard bag. Isolating the fruit from the external environment protects it during development from mechanical or biotic damage, especially in regions where fruits are prone to attacks by fungi, bacteria, insects and even birds. The expected increasing fruit skin color in comparison to non-bagged fruits can therefore correspond either to a reduction or an increase in color or even a greater homogeneity of the color itself.
 The aim of this research was to determine how the application of post-harvest aids affects the quality of fruits and storage capacity of three cultivars of late-ripening apples (Breaburn, Fuji and Pink Lady). Applying summer pruning and covering apple fruits with cardboard bags has a positive effect on increasing the surface of the complementary color on the skin of the fruit.In addition, the influence of these measures on the physical and chemical properties of the fruits after harvest and storage for a period of four months was examined. The experiment was set up in 2019 in a completely randomized design with five replications in the nine leaves old orchards of the Faculty of Agriculture in Belgrade. The used pre-harvest treatments influenced the increase in yield, fruit firmness, and chemical composition. The summer pruning of branches four weeks before harvesting significantly improve percentage of fruit skin color to all examined cultivars, while bagging of fruits only had increased of fruit skin to cultivar Breaburn. 

Saco de polietileno expansível pode melhorar a qualidade do abacaxi cv. ‘MD-2’

ABSTRACT: Paper and plastic bags have been mainly used in fruit bagging of pineapple production. However, they are often discarded as agricultural wastes after harvest of pineapple fruit and threaten environment. In this study, effects of white non-woven fabric bag, expandable polyethylene bag, black plastic bag and kraft paper bag on fruit quality of pineapple cv. ‘MD-2’ were investigated. Results showed that fruits with fruit bagging showed no sunburn. When expandable polyethylene bag was used, fruits of pineapple cv. ‘MD-2’ showed better external qualities, nutrition qualities and texture properties. Expandable polyethylene bag made of degradable and recyclable materials could be recommended as a promising practice to reduce agricultural waste in pineapple production.

Degradation of conventional, biodegradable and oxo-degradable microplastics in a soil using a δ13C technique

Context A significant amount of conventional plastics waste, especially in the form of microplastics (MPs), has accumulated in soils due to its limited degradation. Oxo-degradable and biodegradable plastics have also contributed to MP contamination in soils. Aims In this study, we examined the degradation of a conventional plastic [fruit and vegetable (F&V) bag], two biodegradable plastics (bin liner and mulch film) and an oxo-degradable plastic (drinking straw). Methods These plastics (5 mm) were mixed into a soil and incubated in the laboratory at 37 ± 1°C for 185 days. The CO2-carbon (C) mineralisation of the four plastics was determined using a δ13C technique, because the difference in the δ13C values of studied plastics and the experimental soil was ≥10‰. Key results Bin liner showed the greatest C mineralisation (5.7%), followed by mulch film (4.1%), straw (0.4%) and F&V bag (0.3%) at the end of the incubation period. All plastics, except the mulch film for 23–77 days of incubation, caused a positive priming effect on soil organic carbon (SOC). Fourier transform infra-red spectroscopy and scanning electron microscopy analyses were consistent with the C mineralisation data. Conclusions This study determines the degradation of various MPs in soil using a reliable and practical δ13C method, which has been lacking in this field of study. The priming effect of various MPs on SOC is a significant finding. Implications The lack of consideration of priming effect on SOC may overestimate the mineralisation of plastics in soil.

Application of Decision-Making Trial Evaluation and Analytical Network Process to Fruit Bag in Service Design

We explored the causal relationship and importance of evaluation factors to purchasing decisions taking the service design of Kiwi bag design for consumers as the research object and using decision-making trial evaluation (DEMATEL). The three most important key evaluation factors before purchasing Kiwi bags were found to be “beauty”, “operability” and “durability”. “Beauty” was the influencing factor while “operability” was the main factor. It is recommended to consider these factors to design bags and to investigate possible directions for the evaluation. In the modeling process, it is necessary to quantitatively evaluate simple factors chosen from complex interacting factors and use the results to determine future designs.

Investigations of Multiple Approaches to Reduce Green Spot Incidence in ‘WA 38’ Apple

A pre-harvest apple (Malus × domestica Borkh.) disorder named “green spot” (GS) was recently identified on ‘WA 38’ apples. Previous work indicated a tentative association between GS and fruit mineral imbalance, and an influence of rootstock selection on GS frequency; however, the specific causes, risk factors, and mitigation steps have not been explored. In this study, the role of microclimate, modified using netting or fruit bagging, on GS incidence in ‘WA 38’ apples over two years on two different dwarfing rootstocks, ‘Geneva 41’ (‘G.41’) and ‘Malling 9-Nic29’ (‘M.9’), was investigated. Early season fruit bagging reduced GS appearance, but netting showed mixed results between year and rootstock. Rootstock selection influenced GS incidence, especially in the 2021 season. Fruit mineral analyses highlighted some differences of mineral composition between symptomatic and asymptomatic apples, which helped to corroborate earlier reports; however, within the full context of these results, it is not clear that nutrient imbalance directly influences disorder incidence. Further work to understand the mechanisms behind GS emergence should consider environmental factors, including light, humidity, and wind, as well as anatomical features of ‘WA 38’ fruit, such as lenticel morphology and physiology.

Production, Use and Recycling of Fruit Cultivating Bags in China

Preharvest bagging is a key agricultural technology in the process of the growth and development of young fruits. It can effectively improve the appearance quality of fruits, reduce pesticide residues on the surface of fruits and prevent pests and birds from harming fruits. China is one of the world’s major fruit producers. It is also the country that uses the most fruit cultivating bags. At present, the fruit cultivating bags used in Chinese orchards are mostly paper. Ways to recycle and reuse the waste fruit cultivating bags should be paid attention to. Therefore, this paper comprehensively uses the methods of data analysis and literature research to summarize and analyze. The data mainly comes from the China Rural Statistical Yearbook, a national public service platform for standard information, China’s national knowledge internet and the web of science. The topics discussed include the current situation of fruit production in China, the overview of fruit bagging technology, the production and use of fruit cultivating bags and the recycling strategy of waste fruit cultivating bags. It is hoped that this study can provide some references to the development of fruit bagging technology and the resource reuse and recycling of waste fruit cultivating bags in China and the world in the future.

Titik Kritis Pengendalian Lalat Buah pada Jambu Kristal di Karanganyar

Crystal guava is a popular fruit consumed and developed in Indonesia, this fruit has a high vitamin C content and is widely liked. Consumer demand for crystal guava is getting higher. One of the main obstacles in the cultivation of crystal guava is the attack of fruit fly pests, fruit fly attacks can reduce productivity up to 100 percent. The most effective way to control fruit flies is to do fruit bagging since childhood. The purpose of this study was to determine the most appropriate time to do bagging so that guava crystals are safe from fruit fly attacks and to find out the types of fruit flies in Karanganyar. with purposive sampling, namely guava fruit that is 3 weeks old after blooming, with variations in bagging time at 3, 4, 5, 6, 7, 8, 9, and 10 weeks as well as controls. Observations of fruit fly attacks were carried out periodically and shortly after harvest. The results showed that bagging time had an effect on the intensity of fruit fly attacks. To obtain quality crystal guava, the best time to do the extraction is on the 5th week after the guava flowers bloom. Based on the results of the identification of fruit fly species that attack crystal guava in Karanganyar is Bactrocerra dorsalis.

Effects of Bagging of the Panicles of Philippine Carabao Mango (Mangifera indica L.) Using Waxed Paper Bags

The present study was conducted in Brgy. Dangcol, Balanga City, Bataan to evaluate the effect of bagging the whole panicle (cluster) of carabao mango fruit with waxed paper bag as compared to traditional method of bagging and without bagging in terms of fruit yield and quality as well as in cost-benefit analysis. Results revealed that fruits bagged per cluster using waxed paper (T3) obtained the highest number of marketable fruits (130.60) and highest total weight of 34.21 kg while the number and weight of XL fruits with no bag (T1) were significantly higher as compared to those bagged in cluster using waxed paper (T3). Insect damage was observed in fruits bagged per cluster using waxed paper bag (T3) while there is a scab in fruit with no bag (T1). Meanwhile, there is a wind scar observed in the two bagging methods (conventional bagging method and fruits bagged per cluster using waxed paper bag). All bagging treatments were comparable in terms of physical and chemical characteristics except for peel color which is lighter green in bagged fruits. In terms of income, mango fruits bagged per cluster using waxed paper bag (T3) had the highest gross income of PhP 3,056.27 while the highest net income and ROI was recorded in fruits bagged in conventional method (T2) earning PhP 616.09 per tree with 27.23% ROI. The conventional method (T2) also obtained the lowest cost per tree (PhP 2,262.36) while the lowest cost per kilogram (PhP 73.05) and cost per fruit (PhP 19.14) was recorded in mango trees bagged per cluster using waxed paper bag (T3).

Fruit bagging reduces the postharvest decay and alters the diversity of fruit surface fungal community in ‘Yali’ pear

BackgroundFruit bagging is an effective technique for fruit protection in the orchard management. Bagging can create a micro-environment for fruit growth and affect fruit quality during storage, in which the diversity of microorganisms may play an important role. Therefore, various methods including biochemistry, analytical chemistry, and bioinformatics methods were used to reveal the influences of fruit bagging on postharvest fruit quality, physiological characters, decay and surface fungal community of ‘Yali’ pear fruit were investigated in this study.ResultsFruit bagging significantly decreased the postharvest decay after 15 days of ambient storage. There were no significant differences in fruit firmness, titratable acid and ethylene production rate between the fruit-bagging and non-bagging group after 15 days of storage, while the soluble solids contents (SSC) and respiration rate in non-bagging fruit was significantly higher than that in fruit-bagging after 15 days of storage. Furthermore, the surface microbes of pear were collected and determined by the new generation sequencing technology. The alpha diversity of fungi in non-bagging fruit decreased significantly after 15 days of storage, while there were no significant changes in bagging fruit. Ascomycota and Basidiomycota were the two major phyla detected in the bagging fruit, and the dominant fungal genera were Alternaria (23.7%), Mycosphaerella (17.25%), Vishniacozyma (16.14%), and Aureobasidium (10.51%) after 15 days of storage. For the non-bagging pear, Ascomycota was the only phylum detected, and the dominant genera was Pichia (83.32%) after 15 days of storage. The abundance of Pichia may be regarded as the biomarker to indicate the degree of fruit decay.ConclusionsThis study showed that fruit bagging could significantly reduce postharvest fruit decay and respiration rate of ‘Yali’ pear. Significant differences were found in fungal composition between bagging and non-bagging pear after storage for 0 or 15 days. Fruit bagging maintained the diversity of fungi on the fruit surface, increased the abundance of non-pathogenic fungi, and even antagonistic fungi such as Aureobasidium, Vishniacozyma, and Mycosphaerella. A reduction in the abundance of pathogenic fungi and incidence of postharvest decay during the storage of ‘Yali’ pear were also recorded. In conclusion, fruit-bagging changed the fungal diversity on fruit surface of ‘Yali’ pear, which had significant effect on reducing postharvest fruit decay, and thus prolong the storage period of ‘Yali’ pears. The future thrust of this study will focus on the isolation of fungi or bacteria from pear fruit surface and identify their roles in causing fruit decay and changing fruit quality during storage.

Overexpression of PSY1 increases fruit skin and flesh carotenoid content and reveals associated transcription factors in apple (Malus × domestica).

Knowledge of the transcriptional regulation of the carotenoid metabolic pathway is still emerging and here, we have misexpressed a key biosynthetic gene in apple to highlight potential transcriptional regulators of this pathway. We overexpressed phytoene synthase (PSY1), which controls the key rate-limiting biosynthetic step, in apple and analyzed its effects in transgenic fruit skin and flesh using two approaches. Firstly, the effects of PSY overexpression on carotenoid accumulation and gene expression was assessed in fruit at different development stages. Secondly, the effect of light exclusion on PSY1-induced fruit carotenoid accumulation was examined. PSY1 overexpression increased carotenoid content in transgenic fruit skin and flesh, with beta-carotene being the most prevalent carotenoid compound. Light exclusion by fruit bagging reduced carotenoid content overall, but carotenoid content was still higher in bagged PSY fruit than in bagged controls. In tissues overexpressing PSY1, plastids showed accelerated chloroplast to chromoplast transition as well as high fluorescence intensity, consistent with increased number of chromoplasts and carotenoid accumulation. Surprisingly, the expression of other carotenoid pathway genes was elevated in PSY fruit, suggesting a feed-forward regulation of carotenogenesis when this enzyme step is mis-expressed. Transcriptome profiling of fruit flesh identified differentially expressed transcription factors (TFs) that also were co-expressed with carotenoid pathway genes. A comparison of differentially expressed genes from both the developmental series and light exclusion treatment revealed six candidate TFs exhibiting strong correlation with carotenoid accumulation. This combination of physiological, transcriptomic and metabolite data sheds new light on plant carotenogenesis and TFs that may play a role in regulating apple carotenoid biosynthesis.

On-Tree Fruit Bagging and Cold Storage Maintain the Postharvest Quality of Mango Fruit

The present study investigates the influence of on-tree fruit bagging on the quality and shelf life of mango (Mangifera indica L. cv. ‘Samar Bahisht Chaunsa’) during cold storage (12 °C ± 1; 85–90% RH) for 0, 10 and 20 days (d) and subsequent shelf storage under ambient conditions (25 °C ± 1; 60–65% RH). Fruits were covered with brown paper bags at the marble stage and then harvested at commercial maturity. Results showed that 0 d and 10 d cold-stored fruits, irrespective of bagging treatments, retained eatable quality and shelf-life up to 7 d and 5 d during ambient storage, respectively. However, bagged fruits had better postharvest performance compared with non-bagged fruits by exhibiting slower weight loss, higher fruit firmness, more total soluble solids, vitamin C and total phenolic content and higher activities of catalase and superoxide dismutase during cold storage and ambient shelf storage. On the other hand, 20 d cold-stored fruits, both bagged and non-bagged, were decayed when kept under ambient conditions. It is proposed that mango fruit bagging could be a potential cultural practice to preserve postharvest quality up to 10 d of cold storage, followed by 5 d under ambient conditions.

Impact of fruit bagging and postharvest storage conditions on quality and decay of organic nectarines

ABSTRACT Abiotic factors such as light influence the physicochemical properties of fruit and may alter the response of the fruit to the environment. The aim of this study was to investigate the effect of two postharvest storage conditions on the overall quality and natural fungal disease incidence (fruit decay) of organic nectarines. Experiments were conducted with four organically grown nectarine cultivars (two early-mid season and two late-season) that were unbagged or bagged during preharvest. After harvest, they were stored for 7–9 days in darkness or under a treatment with lighting. Quality parameters (weight, diameter, firmness, soluble solids content, titratable acidity, and single index of absorbance difference), ethylene production, and fruit decay (% incidence of decay) were evaluated. Preharvest bagging reduced fruit decay in the late-season cultivars, for which storage under darkness reduced fungal decay (up to 100%) more than storage under lighting treatment (47% reduction). Bagging altered the initial fruit quality, but values were within official recommendations. Storage conditions reduced differences attributed to bagging, especially under storage with lighting. This work highlighted the importance of modulating the light, both in the field by fruit bagging and during postharvest, to reduce fruit decay and improve fruit quality. These results may serve as a tool for both farmers and postharvest chain managers.

Effect of fruit bagging on control damage of fruit borers and fruit quality of longan (Dimocarpus longan Lour.) cv. Edor

The study investigated the damage situation of fruit borers on longan in Dong Thap, Tien Giang, and Vinh Long provinces and evaluated the effect of different fruit bagging materials on preventing harmful fruit borers and fruit quality of longan cv. Edor during 2019-2020. The experiment arranged in a randomized complete block design (RCBD) four replications and five treatments. The treatments were non-woven bag, Bikoo micro-hole bag, Agro-net bag (49 holes.cm-2), white cotton bag, and control (uncovered fruits). The investigation indicated that fruit borers appeared and caused damage fruit from 2 weeks after fruit set to harvesting time. The percentage of infected fruit of longan orchards were high at 4 weeks after fruit set (1.75%) in Dong Thap, and in Tien Giang, Vinh Long provinces at 10 weeks after fruit set (1.46% and 2.04%, respectively). During 12 weeks from fruit bagging to harvest, bagging of fruits by four types of material did not damaged by fruit borers. However, control treatment increased the rate of infected fruits continuously (7.22% at harvest time). Agro-net bag (49 holes.cm-2), Bikoo micro-hole bags, and white cotton bag were low fruit drop rate (30.73%, 30.65%, and 32.11%) when compared to control (47.14%). From the results obtained conclusion that application of fruit bags on longan cv. Edor was highly effective in preventing damage from fruit borers and ultimately production free from pesticides residues.

Sunburn disorder in tropical and subtropical fruits. A review

The increase in solar radiation and temperature as a result of climate change and variability has increased sunburn damage to fruits, which highly affects quality and yield in tropical and subtropical fruit plants. Solar injuries increase because of conditions with low relative humidity, fruits left uncovered by foliage, and plantations at higher altitudes as a result of increased UV radiation. Three different types of sunburn on fruits are distinguished: photooxidative sunburn, sunburn browning, and necrosis on the epidermis. Fruits employ self-protection mechanisms against this stress through the production of enzymatic and non-enzymatic antioxidants. Fruit growers try to mitigate the impact of sunburning by planting species and varieties that are tolerant to this stress, pruning and training plants, leaving enough leaves above the fruit, efficient irrigation and intercropping for shading. More technical sunburn mitigation strategies include 1) improving the microclimate (shading nets, fruit bagging, evaporative cooling), 2) suppressors (kaolinite clay particle films, calcium carbonate) or 3) chemical protection (tocopherol, abscisic acid, ascorbic acid, anti-transpirants). This paper presents the state of research and its results for this abiotic stress in some tropical and subtropical fruit trees, such as avocado, banana, citrus, mango, pineapple and pitaya, along with observations for other fruit trees in tropical altitude zones. Continued research is recommended for this stress in different varieties with the use of environmentally friendly protective materials, along with studies on molecular mechanisms that direct the acclimatization of plants to a combination of these two types of stress, excessive radiation and temperature.

Transcriptome and Metabolome reveal AsA regulatory network between metabolites and genes after fruit shading by bagging in kiwifruit (Actinidia eriantha)

• The molecular mechanism of AsA changes in Actinidia eriantha after bagging has been studied for the first time. • Through untargeted metabolomics and RNA-Seq of the A. eriantha ‘Ganlv 1′ fruit after bagging were analyzed to reveal the metabolites changes and the underneath gene expression network changes. • Provide novel insights into the effects of bagging on changes in the intrinsic and appearance quality of A. eriantha fruit. Fruit bagging is an effective way of producing pollution-free fruit. However, the micro-environment provided by bagging for fruits could reduce the internal quality for most fruits in various degree. As a novel berry fruit, kiwifruit ( Actinidia eriantha ) has great potential for development. We found a change in fruit quality after fruit shading by bagging (FSB). In order to explore the regulatory mechanism of FSB on fruit quality, we used off-target metabolomics and transcriptomics to identify differential metabolites and differential genes, and focused on the molecular mechanism of the decrease in AsA content. We found that the contents of soluble solids (SSC), soluble sugar (SS), ascorbic acid (AsA), chlorophyll and carotenoid in the FSB fruit were significantly reduced. Through the non-targeted metabolome, a total of 160 metabolites showed significant differences in fruit tissue. There were 3,200 differentially expressed genes (DEGs) between FSB and control by RNA-Seq and enriched in 118 KEGG metabolic pathways. The decrease of AsA content after FSB was mainly due to the decrease of DHAR gene, MDHAR gene, APX gene and the increase of MDHA metabolite during the AsA-GSH cycle process. The decrease of GalUR gene in d -galacturonic acid pathway and the decrease of GulLO gene and Myo-inositol metabolite in Myo-inositol pathway were the secondary reasons for the decrease of AsA content. This study would provide novel insights into the effects of FSB on changes in the intrinsic and appearance quality of A. eriantha fruit.

Ethylene Inhibits Anthocyanin Biosynthesis by Repressing the R2R3-MYB Regulator SlAN2-like in Tomato.

Fruit ripening is usually accompanied by anthocyanin accumulation. Ethylene is key in ripening-induced anthocyanin production in many fruits. However, the effects of fruit ripening and ethylene on anthocyanin biosynthesis in purple tomato fruits are unclear. This study shows that bagged fruits of the purple tomato cultivar ‘Indigo Rose’ failed to produce anthocyanins at the red ripening stage after bag removal. In contrast, the bagged immature fruits accumulated a significant amount of anthocyanins after removing the bags. The transcriptomic analyses between immature and red ripening fruit before and after bag removal revealed that anthocyanin-related genes, including the key positive R2R3-MYB regulator SlAN2-like, were repressed in the red ripening fruit. The 86 identified transcription factors, including 13 AP2/ERF, 7 bZIP, 8 bHLH and 6 MYB, showed significantly different expressions between immature and red ripening fruits. Moreover, subjecting bagged immature fruits to exogenous ethylene treatment significantly inhibited anthocyanin accumulation and the expression of anthocyanin-related genes, including the anthocyanin structure genes and SlAN2-like. Thus, ethylene inhibits anthocyanin biosynthesis by repressing the transcription of SlAN2-like and other anthocyanin-related genes. These findings provide new insights into anthocyanin regulation in purple tomato fruit.

Effect of Pre-Harvest Bagging on Pomegranate cv.Salimi Fruits Characteristics

This study was carried out on 5-yrs old pomegranate trees cv.Salimi grown in a private orchard located at Otomaniyah area, Diyala Governorate, Iraq during 2018 and 2019 growing seasons to study the effect of Pre-harvest fruits bagging on reducing pomegranate fruit disorders and improving fruit quality. The bagging treatments were, Control (without bagging), Fruit bagged with green, white, red and purple colors bags. Treatments started on May30 during both seasons. Non-woven fabric bags (25x25cm) was used in fruit bagging. Bags were removed two weeks before harvesting date. The obtained results showed that, bagging fruits with white bags gave the highest average of fruits weight, Aril percentage, 100 aril weight, total soluble solids(%), total sugars and anthocyanins during both seasons compared to other Bagging treatments, whereas there is no significant differences between the bagging treatments in nutrient content of the fruit peel. on the other hand these treatments reduced cracked fruits and sunburn percentage, and increased the moisture content of the fruit peel compared to the Control (without bagging).
