Project description:We sequenced mRNA from immature green (15 days after anthesis) and red (Breaker+10 days) tomato (Solanum lycopersicum) fruit tissues from plants over-expressing SlGLK1 and SlGLK2 and from control plants 'M82' to compare gene expression levels between transgenic fruit and the control. Note: Samples in SRA were assigned the same sample accession. This is incorrect as there are different samples, hence “Source Name” was replaced with new values. Comment[ENA_SAMPLE] contains the original SRA sample accessions.
Project description:The tomato SlWRKY3 transcription factor was overexpressed in cultivated tomato (Solanum lycopersicum)and transgenic plants transcriptome was compared to that of wild-type plants.
Project description:Plants represent the nutritional basis of virtually all life on earth and protein-rich foods from crop plants are a global megatrend essential for sustaining an increasing human population and counteracting climate change. While the genomes of crops are increasingly elucidated, little is known about crop proteomes – the entirety of proteins that execute and control nearly every aspect of life. To address this shortcoming we optimized a protocol for mapping the proteome of different crops such as Solanum lycopersicum (tomato) fruit and included four technical replicates and three biological replicates from different tomato plants to demonstrate the robustness of the workflow.

Project description:RNA sequencing in tomato for detect mRNA expression of Solanum lycopersicum flower.The two cultivars (monomaker, raceme) had three different flowering stages (budlet, Flower bud, Full bloom) for transcriptome sequencing
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 the present study, we demonstrated that application of CaCl2 to ‘Micro Tom’ tomato fruit (mature green stage) delayed fruit senescence and mature.
Project description:The tomato SlWRKY3 transcription factor was overexpressed in cultivated tomato (Solanum lycopersicum)and transgenic plants transcriptome was compared to that of wild-type plants. At least 4 plants were collected for RNA extraction. The aim of the experiment was to compare transcriptomes of 35::SlWRKY3 plants and wild-type plants grown together and on MS (Murashige and Skoog) medium in vitro for 4 weeks. A technical replicate (dye swap) was conducted.
Project description:Members of the tomato clade exhibit wide diversity in fruit coloration, growth habit, leaf morphology and mating preferences. However, the mechanisms governing inter-species diversity in fruit coloration are largely unknown. Therefore, a proteomic approach combined with carotenoid profiling and carotenogenic gene expression was used to decipher the diversity in carotenogenesis in green-fruited Solanum habrochaites, orange-fruited S. galapagense, and red-fruited S. pimpinellifolium with S. lycopersicum, cv. Ailsa Craig (tomato).
