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: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:Anthocyanins are high value plant antioxidants which are not present in the fruits of cultivated tomato. However, both the dominant gene Anthocyanin fruit (Aft) and the recessive gene atroviolacea (atv), introgressed into domesticated tomato from two different wild Solanum species, stimulate a limited anthocyanin pigmentation. Surprisingly, double mutant Aft/Aft atv/atv tomatoes are characterised by the presence of anthocyanins in the fruit peel, resulting in intensely purple pigmented fruit. We carried out a transcript profiling analysis using GeneChip® Tomato Genome Arrays, in order to identify differentially expressed genes when comparing wild type, Aft/Aft, atv/atv, and Aft/Aft atv/atv fruits. The expression pattern of several genes involved in the anthocyanin pathway was analyzed in detail. Among the fruit peel-associated differentially expressed transcripts, genes involved in phenylpropanoid pathway, cell wall composition, biotic and abiotic stress responses, sugar and hormone metabolism were overrepresented in Aft/Aft atv/atv. Transcriptomic analysis thus revealed that the activation of anthocyanin synthesis in tomato fruit was accompanied by a complex remodulation of gene expression, likely affecting important agronomic and merceological traits.

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.

Wild type (Cv. Ailsa Craig, accession number LA2838A), Aft/Aft (accession number LA1996), atv/atv (accession number LA0797) and double mutant (Aft/Aft atv/atv) were grown during the winter season in a controlled heated greenhouse. Fruits were collected at mature green, turning red and red stages of development. The transcriptional profile in Aft/Aft, atv/atv, and Aft/Aft atv/atv fruits when compared to the wild type was analyzed using the GeneChip® Tomato Genome Array.

Project description:Gene regulation in parthenocarpic tomato fruit
| PRJNA111389 | ENA
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.
