Project description:RNA-Seq was conducted among sergeant bulks of four sex types of melon flowers, namely monoecious (AAGG), gynoecious (AAgg), hermaphrodite (aaGG), and andromonoecious (aagg), a total of about 105 million reads were generated from the melon transcriptome using Solexa sequencing.Totally 79,698 unigenes were generated and 75,537 unigenes were mapped to 11,805 annotated proteins in assembled melon genome (Garcia-Mas et al., 2012). Transcripts related to photomorphogenesis and flower development in plants were found, Most of the genes encoding plant hormone metabolism related protein, others related to flora development including Tasselseeds and male sterility genes which in phytohormones pathway were also detected. Comparison each two bulks (AAGG:AAgg, AAGG:aaGG, aagg:AAgg and aaGG:aagg ) exhibited different profiles of putative genes (include 745, 1342, 858 and 571 different expression genes, respectively). mRNA profiles of four sex types of melon flowers, namely monoecious (AAGG), gynoecious (AAgg), hermaphrodite (aaGG), and andromonoecious (aagg) were were generated by deep sequencing using Illumina Hiseq 2000.

Project description:Purpose: We conducted a reverse genetic approach in order to elucidate the role of H3K27me3 writers and erasers in the process of sex determination and expression in melon. Methods: We used TILLING to find loss-of function mutants of cmLHP1 proteins in melon. Selected alleles were phenotyped at the developmental and molecular levels. We generated the cmlhp1ab mutant, for which we observed a pleiotropic phenotype. For this double mutant, we integrated RNA-seq (leaves), ChIP-seq (leaves) and RT-PCR (flowers) for elucidating the impact of cmLHP1 loss of function at the molecular level. Results: cmlhp1ab displayed a pleiotropic phenotype which correlated with genome-wide changes of H3K27me3 (moore oftenly hypomethylation) and deregulation of genes involved in flower development and hormone responses.

Project description:Background: MicroRNAs (miRNAs) represent a family of small endogenous, non-coding RNAs that play critical regulatory roles in plant growth, development, and environmental stress responses. Although Hami melon is an attractive model for valuable biological traits analysis, the role of miRNA action in the fruit development and ripening remains largely unknown. Here, we performed small RNA sequencing to investigate the Hami melon miRNA profiles at four fruit developmental stages Results: Small RNA sequencing yielded raw reads in eight libraries. miRNAs expression profiles were variable at different fruit developmental stages. The expression levels of five known miRNAs were validated by quantitative real-time PCR. Among the identified miRNAs, several miRNAs showed developmentally regulated and differentially expressed pattern during fruit development. Conclusions: Our results present a first comprehensive set of identification and characterization of Hami melon fruit miRNAs and their potential targets, which provide valuable basis for further research on the critical role of miRNAs in melon fruit development.

Project description:In deciduous fruit trees, entrance into dormancy occurs in later summer/fall, concomitantly with the shortening of day length and decrease in temperature. Generally speaking, dormancy can be divided into endodormancy, ecodormancy and paradormancy. In Prunus species flower buds, entrance into the dormant stage occurs when the apical meristem is partially differentiated; during dormancy, flower verticils continue their growth and differentiation. In this work we focused our attention on flower bud development during winter in peach. In order to understand how bud development progress is regulated during winter we integrated cytological epigenetic and chromatin genome wide data with transcriptional outputs to obtained a complete picture of the main regulatory pathways involved in endodormancy.

Project description:Melon (Cucumis melo L.) is a commercially important fruit crop that is cultivated worldwide. The melon research community has recently benefited from the determination of a complete draft genome sequence and the development of associated genomic tools, which have allowed us to focus on small RNAs (sRNAs). These are short, non-coding RNAs 21â24 nucleotides in length with diverse physiological roles. In plants, they regulate gene expression and heterochromatin assembly, and control protection against virus infection. Much remains to be learned about the role of sRNAs in melon. We constructed 10 sRNA libraries from two stages of developing ovaries, fruits and photosynthetic cotyledons infected with viruses, and carried out high-throughput pyrosequencing. We catalogued and analyzed the melon sRNAs, resulting in the identification of 26 known miRNA families (many conserved with other species), the prediction of 84 melon-specific miRNA candidates, the identification of trans-acting siRNAs, and the identification of chloroplast, mitochondrion and transposon-derived sRNAs. In silico analysis revealed more than 400 potential targets for the conserved and novel miRNAs. This analysis provides insight into the composition and function of the melon small RNAome, and paves the way towards an understanding of sRNA-mediated processes that regulate melon fruit development and melonâvirus interactions.

Project description:Virus resistances that are recessively inherited are associated with loss-of-susceptibility resistance alleles. Resistance to Watermelon mosaic virus (WMV) of melon accession TGR-1551 is expressed as a drastic reduction of the virus titer, and is recessively inherited. In this work, viral RNA accumulation was measured in TGR-1551 and in susceptible WMV-infected melon plants by real time quantitative PCR (qPCR), and gene expression of 17,443 unigenes represented in a melon microarray was monitored in a time-course experiment. Virus accumulation was higher in inoculated cotyledons of the resistant genotype up to 7 days post-inoculation; from this time on, virus accumulation was much higher in plants of the susceptible genotype. Microarray experiments were carried with samples from inoculated cotyledons at 1 and 3 dpi to monitor early changes in response to virus infection, and at 7 dpi. Samples from systemically infected leaves harvested at 15 dpi were also included in the analysis. Results showed much more profound transcriptomic alterations in resistant plants compared to susceptible ones. Analyses of gene expression profiles reveal deep and extensive transcriptomic alterations in TGR-1551 plants, many of them involving pathogen response-related genes. Overall, data suggested that resistance to WMV in TGR-1551 is associated with a defense response, contrasting with its recessive nature. Two melon genotypes have been used to analyse transcriptomic responses to infection by Watermelon mosaic virus: Tendral (susceptibel to WMV) and TGR-1551 (resistant to WMV). For each genotype, 60 melon seedlings were inoculated with WMV-M116 and another 60 were mock-inoculated. Cotyledons of 10 plants were harvested at 1, 3, 5, 7, 9 and 15 dpi. At 15 dpi, the systemically infected second true leaf was also harvested. To reduce variability, each biological replicate used in this study was prepared by mixing the RNA extracts from 2 or 4 mock or WMV-inoculated cotyledons, respectively, or from 3 melon leaves. Samples (WMV infected and mock inoculated) corresponding to cotyledons at 1, 3 and 7 dpi, and leaves at 15 dpi were used for microarray hybridisations, three biological replicates for each one, leading to a total of 48 samples.
