A naturally unique variation in Al-activated malate transporter 9 determines fruit malate in cultivated tomato

Project description:Purpose: Understanding the mechanism of malate accumulation in plants is beneficial for both plant nutrient and human health. However, little is known regarding regulation of malate accumulation in horticulture plants such as tomato. The goals of this study are to investigate potential regulation network of Al-Activated Malate Transporter 9 (ALMT9) which is the major locus responsible for the variation in fruit malate concentration observed in cultivared tomato. Methods: The transcriptomes of fruit at ripening stage from CK and SlALMT9 overexpressing line1 were evaluated using single-ended sequencing of Illumina HiSeq 2500. Raw sequences were filtered and the resulting sets of clean reads were used for the following analysis by tophat and edgeR software. Results: Among 1,887 differentially expressed genes, some structural genes involved in sugar and organic acid metabolism were differently expressed in SlALMT9 overexpressing line, which partially coincide with changes of sugar and organic acid concentration. PR genes was also altered in the OX lines, in agreement with previous study that tomato fruit malate is involved in pathogen infection. Three members of malate transporters, MATE (multidrug and toxin efflux), were up-regulated (SlMATE5 and 6) or down-regulated (SlMATE9) . Besides, three sugar transport proteins and four vacuole membrane or plasma membrane proteins were up-regulated in OX line Conclusions: Using RNA-seq analysis, 1,887 differentially expressed genes was revealed. Among them, several genes related to sugar and organic acid metabolism and transport, pathogen resistances were identified. This transcriptome study provides insight into the regulatory mechanism of fruit malate accumulation and the effect of the SlALMT9 to primary metabolism.

The impact of growing area on the expression of fruit traits re-lated to sensory perception in two tomato cultivars

Project description:The environmental conditions greatly influence tomato fruit quality, by affecting the expression of genes, the abundance of metabolites and the perception of sensorial attributes.In this study, a fruit transcriptome investigation, together with a sensory test and a metabolomic analysis were per-formed to evaluate the impact of the environment on two popular tomato cultivars grown in two Italian regions. The transcriptional profile of each cultivar, cultivated in two different areas high-lighted differential expression in genes involved in pathways related to cell wall components such as pectin, lignin and hemicellulose, sugars as well as in amino acids, phenylpropanoids, and pigment synthesis. The cultivation area mainly affects sensory attributes related to texture and flavor and the metabolic pattern of cell wall precursors, sugars, glutamate, aspartate and carotenoids. In the two genotypes cultivated in the same environment, some attributes and fruit-related quality processes are similarly affected, while others are differently influenced based on tomato specific genetic makeup. Combination of transcriptomic, sensory and metabolomic data obtained from the two tomato genotypes revealed that the environment has a profound effect on specific sensory traits, providing information on factors that shape the specific characteristics and genetic targets for im-proving tomato fruit characteristics.

Expression of genes in red fruit of Andean tomato (Solanum lycopersicum) and Solanum pimpinellifolium

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.

Solanum lycopersicum strain:M82 Transcriptome or Gene expression

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.

Transcriptome sequencing of 7 tissues of S. lycopersicum and 2 of its closely related wild ancestor S. pimpinellifolium

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.

Transcript profiling of tomato mutants producing anthocyanins in the fruit

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.
