Project description:We analysed the DNA methylation and transcription levels of transposable elements and genes in leaves of Prunus persica and Prunus dulcis and in their F1 hybrid using high-throughput sequencing tecnhologies. We can conclude that the merging of the two parental genomes in the P. persica x P. dulcis hybrid does not result in a “genomic shock” with significant changes in the DNA methylation or in the transcription.

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:Trichomes in Prunus persica (L.) Batsch are crucial specialized structures that play a protective role against both biotic and abiotic stresses. The fruits with and without trichomes are respectively named as peach and nectarine. At the genetic level, the formation of trichome in peach is controlled by a single gene, PpMYB25, at the G locus. Peach (GG or Gg) is dominant to nectarine (gg), but such regulatory role was reported in a small-scale accessions. In this study, we performed large-scale genotype and phenotype screening on 295 accessions. Almost all accessions supported the casual relationship between trichome formation and PpMYB25. However, a peach to nectarine mutant, named Maravilha Nectarine Mutant (MN), was discovered to possess a putative functional PpMYB25 gene sequence (Gg) but revealed nectarine phenotype. Comparative transcriptomic analyses revealed that PpMYB25 transcript was absent in MN. Correlation analyses also demonstrated that the PpMYB25-mediated regulatory network was abolished in MN. In summary, our results demonstrated an alternative mechanism beyond genetic regulation on trichome formation.
