Project description:[original title] Understanding the complexity of fruit ripening by transcriptome analysis of rin mutant fruit and in silico analysis of promoters of differentially regulated genes A tomato MADS-box transcription factor, LeMADS-RIN, controls fruit ripening and mutation in this gene results in non-ripening phenotype of fruit. This mutation down-regulates certain ripening related ethylene responses, however, other ethylene responses are normal. A complete understanding of this mutation and its effect on fruit transcriptome during ripening is not clear. In this study, microarray analysis has been used to investigate the influence of rin mutation on fruit transcriptome at different stages of ripening. A total of 2,398 genes were found to be differentially expressed in wild type fruit pericarp, which on cluster analysis indicated a major shift in their expression profiles in rin mutant fruit. A total of 1,802 genes were found to be differentially expressed between wild type and rin mutant fruits and 17% of these genes encoded regulatory elements, suggesting that mutation in LeMADS-RIN results in disturbance in the regulatory transcriptional networks during ripening. Since LeMADS-RIN has been reported to bind to the CArG box of LeACS2 promoter, in-silico analysis of 51 putative promoter sequences of the genes, that showed ripening associated up-regulation in wild type but showed impairment in up-regulation in rin mutant fruit during ripening, were searched for presence of CArG box along with ethylene and auxin responsive elements. The study revealed that only 24 putative promoter sequences harbor LeMADS-RIN specific CArG box suggesting an alternative mode of regulation by LeMADS-RIN for CArG box deficient genes. Three chronological stages of tomato (Solanum lycopersicon) fruit ripening were compared between wild type and rin mutant

Project description:Post-translational modification of proteins through methylation plays important regulatory role in biological processes. Lysine methylation on histone proteins is known to play important role in chromatin structure and function. However, non-histone protein substrates of this modification remain largely unknown. Herein, we use high resolution mass spectrometry to global screening methylated substrates and lysine- methylation sites in tomato (Solanum Lycopersicum). A total of 241 sites of lysine methylation (mono-, di-, tri-methylation) in 176 proteins with diverse biological functions and subcellular localized were identified in mix tomato with different maturity. Two putative methylation motifs were detected. KEGG pathway category enrichment analysis indicated that methylated proteins are implicated in the regulation of diverse metabolic processes, including arbon fixation in photosynthetic organisms, pentose phosphate pathway, fructose and mannose metabolism, and cysteine and methionine metabolism. Three representative proteins were selected to analyze the effect of methylated modification on protein function. In addition, quantitative RT-PCR further validated the gene expression level of some key methylated proteins during fruit ripening, which are involved in oxidation reduction process, stimulus and stress, energy metabolism, signaling transduction, fruit ripening and senescence. These data represent the first report of methylation proteomic and supply abundant resources for exploring the functions of lysine methylation in tomato and other plants.

Project description:In this study, we explored the metabolome and transcriptome of the ripe fruit in nine landrace accessions representing the seven genetic groups and compared them to the mature fruit of the wild progenitor S. pimpinellifolium. The goal is to shed light in understanding the factors responsible for acquiring tomato fruit quality (taste and flavour) at molecular level during the domestication process.
