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:Sequencing the metatranscriptome can provide information about the response of organisms to varying environmental conditions. We present a methodology for obtaining random whole-community mRNA from a complex microbial assemblage using Pyrosequencing. The metatranscriptome had, with minimum contamination by ribosomal RNA, significant coverage of abundant transcripts, and included significantly more potentially novel proteins than in the metagenome.

Project description:The fruit of melting-flesh peach cultivars produce high levels of ethylene caused by high expression of PpACS1, resulting in rapid fruit softening at the late-ripening stage. In contrast, the fruit of stony hard peach cultivars do not soften and produce little ethylene due to low expression of PpACS1. To elucidate the mechanism for suppressing PpACS1 expression in stony hard peaches, a microarray analysis was performed. Several genes that displayed similar expression patterns as PpACS1 were identified and shown to be IAA-inducible genes.

Project description:We performed small RNA deep sequencing and identified 47 peach-specific and 47 known miRNAs or families with distinct expression patterns. Together, the identified miRNAs targeted 80 genes, many of which have not been reported previously. Like the model plant systems, peach has two of the three conserved trans-acting siRNA biogenesis pathways with similar mechanistic features and target specificity. Unique to peach, three of the miRNAs collectively target 49 MYBs, 19 of which are known to regulate phenylpropanoid metabolism, a key pathway associated with stone hardening and fruit color development, highlighting a critical role of miRNAs in regulation of peach fruit development and ripening. We also found that the majority of the miRNAs were differentially regulated in different tissues, in part due to differential processing of miRNA precursors. Up to 16% of the peach-specific miRNAs were differentially processed from their precursors in a tissue specific fashion, which has been rarely observed in plant cells. The miRNA precursor processing activity appeared not to be coupled with its transcriptional activity but rather acted independently in peach. Collectively, the data characterizes the unique expression pattern and processing regulation of peach miRNAs and demonstrates the presence of a complex, multi-level miRNA regulatory network capable of targeting a wide variety of biological functions, including phenylpropanoid pathways which play a multifaceted spatial-temporal role in peach fruit development.

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.
