Project description:Low temperature storage of citrus fruits are susceptible to chilling disorder symptoms that impact fruit quality. Understanding the molecular frame underlying the cold storage process will provide a basic guidance for practical control. We used Affymetrix Citrus GeneChip to examine the transcriptional changes in cold-stored Citrus reticulata Blanco cv. âPonkanâ pulp tissue for three successive months. Ponkan postharvest fruits were under cold storage for three successive months. The pulp tissue was used for RNA extraction and hybridization on Affymetrix Citrus Genome microarrays.

Project description:Chayote (Sechium edule) fruits are rich in flavonoids, folate, and low-calorie food. However, studies about the flavonoids and regulatory mechanism of flavonoid synthesis in chayote fruits was still unclear. In present study, a transcriptome analysis and metabolite profiling of chayote fruits at three different storage stages were conducted to explore the flavonoid compositions and gene expression associated with flavonoid synthesis. Through the UPLC-MS/MS analysis, a total of 57 flavonoid compounds were detected. Of these, 42 flavonoid glycosides were significantly differential accumulation in chayote fruits at three different storage stages. Many genes associated with flavonoid synthesis were differentially expressed in chayote fruits at three different storage stages through RNA-seq analysis, including structural genes and some TFs. There was a high correlation between RNA-seq analysis and metabolite profiling, and the expression level of candidate genes in the flavonoid synthesis pathway were consistent with the dynamic changes of flavonoids. In addition, one R2R3-MYB transcription factor, FSG0057100, was defined as the critical regulatory gene of flavonoid synthesis. Furthermore, we treated chayote fruits during storage with phenylalanine, and the results show exogenous phenylalanine applications might promote the flavonoid synthesis. Phenylalanine is a effective additive to maintain or improve the total content flavonoids in chayote fruit during storage, can apply the phenylalanine in the postharvest storage of chayote. The above results not only make us better understand the molecular mechanism of flavonoid synthesis in chayote fruits, but also contribute to the promotion and application of chayote products.

Project description:Background: Anthocyanins are the most important compounds for nutritional quality and economic values of blood orange. However, there are few reports on the pre-harvest treatment accelerate the accumulation of anthocyanins in postharvest blood orange fruit. Here, we performed a comparative Transcriptome and metabolomics analysis to elucidate the underlying mechanism involved in seasonal drought (SD) treatment during fruit expansion stage on anthocyanin accumulation in postharvest ‘Tarocco’ blood orange fruit. Results: Our results showed that SD treatment slowed down the fruit enlargement and increased the sugar accumulation during fruit development and matured period. Obviously, under SD treatment, the accumulation of anthocyanin in blood orange fruit during postharvest storage was significantly accelerated and markedly higher than that in CK. Meanwhile, the total flavonoids and phenols contents and antioxidant activity in SD treatment fruit were also sensibly increased during postharvest storage. Based on metabolome, we found that substrates required for anthocyanin biosynthesis, such as amino acids and their derivatives, and phenolic acids, have significantly accumulated and higher in SD treated mature fruit compared with that of CK. Further according to the results of transcriptome data and weighted gene coexpression correlation network analysis (WGCNA) analysis, phenylalanine ammonia-lyase (PAL3) was considered key structural gene. qRT-PCR analysis verified that the PAL3 was highly expressed in SD treated postharvest stored fruit and was significantly positively correlated with the anthocyanin content. Moreover, we found that other structural genes in anthocyanin biosynthesis pathway were also upregulated under SD treatment through transcriptome data and qRT-PCR analysis. Conclusions: The findings suggest that SD treatment promotes the accumulation of substrates necessary for anthocyanin biosynthesis during fruit ripening process, and activates the expression of anthocyanin biosynthesis pathway genes during postharvest storage period, especially PAL3, co-contributed to the rapid accumulation of anthocyanin. The present study provides a theoretical basis for postharvest quality control and water-saving utilization of blood orange fruit.

Project description:Purpose:Bamboo shoots rapidly lose water and accumulate lignin when stored under room temperature, while low temperature conditioning (LTC, 4℃) can alleviate lignification and reduce weightlessness rate. However, few transcriptional response and profiling datasets are available to explore the LTC mechanism of bamboo shoots.The goal of this study is to provides insights into the regulation of Lei bamboo (Phyllostachys violascens) shoots during postharvest cold storage by transcriptome analysis. Methods:Total RNA was extracted using RNAiso Plus (Takara, Japan) according to the protocol, and after quality testing, was used for library construction and transcriptome sequencing by Illumina Novaseq™ 6000. The quality-controlled reads were aligned to the Phyllostachys edulis reference genome (http://gigadb.org/dataset/100498). The edgeR program25 was used for differential expression analyses. Results: After raw data filtering, a high clean data rate from each sample was achieved, and the assessment result for the clean data by FastQC all demonstrated that our sequencing data was of high quality, full representativeness and validity. Compared with CK, a total of 7,452 DEGs were identified during LT storage. The Pearson’s correlation coefficient (r) and principle component analysis (PCA) results all suggested a high correlation among all samples. The above results suggest an effective LT treatment of postharvest bamboo shoots and a high-quality bioinformatics analysis of our RNA-seq results. Conclusions: Our study represents the first detailed analysis of Lei bamboo (Phyllostachys violascens) shoots during postharvest cold storage transcriptomes, with biologic replicates, generated by RNA-seq technology. The optimized data analysis workflows reported here should provide a framework for comparative investigations of expression profiles. We conclude that RNA-seq based transcriptome characterization would reveal the essence of ripening and senescence of fruits and vegetables.

Project description:The postharvest senescence processes of citrus fruits were analyzed transcriptomic. The present study was aimed to: further uncover the rind-flesh communication of hesperidium; characterize the differential storage behaviors of different citrus varieties; reveal the important changes during storing process; and demonstrate the specific non-climacteric characteristics of citrus fruits. We chose four major table fruit varieties of citrus: satsuma mandarin (Citrus unshiu Marc) (M), ponkan (Citrus reticulata Blanco) (K), newhall navel orange (Citrus sinensis L. Osbeck) (O) and shatian pummelo (Citrus grandis Osbeck) (P). They were sampled every 10 days during 50 DAH (days after harvest), almost covering the commercial storage period of loose-skin citrus.

Project description:Storage at low temperatures is one of the most used methods to prolong the life of postharvest peaches (Prunus persica (L) Batch.). However, fruit quality is adversely affected by the development of woolliness, a physiological disorder that is apparent when the fruit is ripened after prolonged periods of cold storage and is mainly manifested as loss of juice in the peaches. The aim of this study was to obtain a more detailed cohort of genes that underlie the wolliness in a segregating population with contrasting phenotypes of mealiness after being exposed to cold storage at 4 °C. For this, a transcriptomics approach was applied to fruits from a progeny of individuals accounted for 6% more juicy and woolly 6% over a 2 years. Our results suggest that not only genes related to the maintenance of cell wall architecture may contribute to the development of mealy phenotype. Based on its possible physiological process and differential pattern of expression transcriptomic profiles show that genes related to maintenance (modification I) and membrane fluidity account for the differences between fruits that exhibit contrasting phenotypes of mealiness. These genes may contribute to tolerance to cold during storage. We analyzed a total of 9 woolly fruits (from 3 different trees, 3 fruits from each tree) and 12 juicy fruits (from 4 different trees, 3 fruits from each tree). An RNA pool from 9 woolly fruits was used as reference and was compared to an RNA pool of 3 juicy fruits from each individual tree. Two technical replicates were done for each comparison, thus making in total 8 hybridizations.

Project description:Purpose: This study was to explore the underlying molecular mechanism of temperature effects on fruit quality during shelf life. The transcriptome data of peach fruits stored in high temperature (HT, 35 °C) and common temperature (CT, 25 °C) conditions were measured and compared. Methods: Red flesh peach (Prunus persica L. Batsch cv. Tianxianhong) fruits with consistent color, shape and weight were selected and kept at 5 °C for 2 days after the day of harvest. Then, these fruits were randomly divided into two groups. One group was stored at CT for 7 days, and the other was stored at HT for 7 days. During storage, fruits were sampled at day 1, 2 and 3 as early stage as well as day 5, 6 and 7 as later stage. Total RNA of each sample was extracted and used to construct 24 RNA libraries. RNA sequencing was performed on an Illumina HiSeq 2500 platform. The differences in transcriptome, ethylene production, pulp softening of postharvest peach fruits were compared between CT and HT storage conditions Results: Our results showed that HT conditioning after 5 °C is better than CT to maintaining fruit quality during shelf life due to MEKK1-MKK2-MPK4/6 signal transduction and low level of ethylene and auxin biosynthesis enzymes which may affect genes related to softening and membrane stability through ethylene response factors (ERFs) and auxin response factors (ARFs).

Project description:Both exogenously supplied and transgenic induced cytokinin production can effectively delay senescence of broccoli florets during postharvest storage. However, a substantial comparison between the mechanisms of these two treatments on delaying broccoli florets senescence was absent. Here, we conduct microarray analysis on broccoli florets of N6-benzylaminopurine treated and ipt-transgenic broccoli that harbor a senescence-associated-gene promoter triggering isopentenyltransferase gene expression during postharvest storage. Analysis used RNA of Green King inbred line 104 as control sample for comparison to the experimental samples of ipt-transgenic line 102, 103 and parental line Green King as well as 10 ppm BA treated Green King at harvest and after postharvest storage at 25 centigrade in the dark for 4 days.
