Project description:Background: During the analysis of ripening related gene expression in tomato fruit, we observed a bias towards certain classes of messenger RNA based upon the type of buffer used in the initial step of the extraction procedure. We postulated that there was a functional association of the separated transcripts. To test this hypothesis, we carried out extractions from the same tissue sample where only the buffer varied. Transcripts were hybridised to Affymetrix oligo arrays and the data was analysed according to the predicted cellular component of the encoded proteins. Results: The use of an extraction buffer that lacked high levels of caeotropic agents resulted in a reduction of mRNAs encoding proteins that were either secreted or were predicted to be routed through the endomembrane system and hence could have been bound to the endoplasmic reticulum in polyribosomes. Extraction of the cell debris immediately following the initial buffer based extraction and subsequent micro array analysis revealed that the expected transcripts could be recovered. This demonstrated that the buffer was separating the mRNAs based on the cellular component of the encoded proteins. Analysis of selected transcripts by northern hybridisation again supported this theory. Conclusions: Some traditional buffers used for fruit RNA extraction selectively deplete for transcripts encoding proteins that are membrane-associated or secreted. This can be explained if polyribosomes that are bound to the endoplasmic reticulum (ER) are not effectively disrupted when the extraction buffer lacks either detergent or organic solvents. These findings have important implications with respect to experimental bias, as well as opportunities for message enrichment and protein characterisation. GeneChip analyses were performed to analyse the effect of using different extraction protocols on Solanum lycopersicum pericarp.

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: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.

Project description:Transcriptome analysis of 7 tissues of commercial tomato (S. lycopersicum cv MoneyMaker) and its wild red-fruited ancestor (S. pimpinellifolium LA0722) genotypes performed to assess expression level of tomato transcriptome and to aid whole genome annotation. Sequencing of fruit at 3 different developmental stages will help to assess gene regulation through ripening.
