Project description:Phenotypes of the tomato (Solanum lycopersicum L.) high pigment-2dg (hp-2dg) mutant are caused by a mutation in the gene encoding DEETIOLATED1, a negative regulator of light signaling. Homozygous hp-2dg plants display a plethora of distinctive developmental and metabolic phenotypes in comparison to their normal isogenic counterparts. This mutant is however best known for the increased levels of lycopene and other plastid-accumulating functional metabolites. In this study we analyzed the transcriptional alterations in mature-green, breaker and early-red fruits of hp-2dg/hp-2dg plants in relation to their normal counterparts using microarray technology. Results show that a large portion of the genes that are affected by hp-2dg mutation, display a tendency for up- rather than down-regulation. Ontology assignment of these differentially regulated transcripts, revealed a consistent upregulation of those related to chloroplast biogenesis and photosynthesis in hp-2dg mutants throughout fruit ripening. A tendency of upregulation was also observed in structural genes involved in phytonutrient biosynthesis. However, this upregulation was not as consistent, positioning plastid biogenesis as an important determinant of phytonutrient overproduction in hp-2dg mutant fruits. Microscopic observations revealed a highly significant increase in chloroplasts size and number in pericarp cells of mature-green hp-2dg/hp-2dg fruits in comparison to their normal counterparts. This increase could be observed from early stages of fruit development. Therefore, the molecular trigger that drives phytonutrient overproduction in hp-2dg mutant fruits should be initially traced at early stages of fruit development.

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.

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: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.
