Project description:To provide insights into how SUN regulates shape and whether this is accompanied with shifts in transcript profiles, we identified differentially expressed genes in eight pairwise comparisons of SUN and wild-type fruit tissues and time points. Lines nearly isogenic for SUN in the cultivated background Solanum lycopersicum c.v. SUN1642 were grown in the greenhouse in a completely randomized design. SA4 is like SUN1642 and SA3 is like WT LA1589 at SUN locus. Flowers at anthesis were tagged and self-pollinated on successive days. Anthesis is defined as when the flower opens. Pollination of flowers was staggered so fruit of all developmental stages would be harvested on the same day. Fruits at stage four, seven, and ten days post anthesis (dpa) were harvested and brought back to the laboratory. Septum, seed, and pericarp tissue were isolated and frozen in liquid nitrogen. Four dpa septum tissues is a mixture of septum and seed tissue. Four dpa pericarp is a mixture of pericarp and exocarp tissue due to small size of four dpa fruits. Seven and 10 dpa pericarp dont contain the exocarp (epidermal) tissues. Four replicates were collected. RNA was extracted using Trizol and Stand-specific libraries were prepared from total RNA and sequences of 51 bp were generated on an Illumina HiSeq2000.

Project description:The transformation of the ovary into a fruit after successful completion of pollination and fertilization has been associated with many changes at transcriptomic level. These changes are part of a dynamic and complex regulatory network that is controlled by phytohormones, with a major role for auxin. One of the auxin-related genes differentially expressed upon fruit set and early tomato fruit development is Solanum lycopersicum ARF9 (SlARF9). To explore the physiological role of SlARF9 in tomato fruit set and development, we generated transgenic tomato lines in which the gene was overexpressed or silenced, and used microarray analysis to identify possible transcriptomic changes associated with the fruit developmental phenotypes observed in the transgenic lines. The transcript profiling analysis was done using pericarp tissue from fruits, 3-4mm in diameter, with each sample containing the pericarp of two fruits. For each seperate transgenic line, tissues were pooled from 2-3 plants (T2), resulting in a total of 6 samples for SlARF9-OE, 7 samples for SlARF9-RNAi, and 2 samples for wild type. The transcript profiling analysis was carried out using affymetrix EUTOM3 tomato exon array.

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:The size of tomato fruits are largely dependent on growth conditions. To obtain insights on how light intensity contributes to translocation from a leaf and a fruit, we developed a plant irradiation system based on light-emitting diodes (LEDs) to a leaf. By using this system, we investigated the changes of transcript profiles of tomato leaves and fruits grown under different light conditions. 20 samples were analyzed (14 leaf samples and 6 pericarp samples); 2-3 biological replicates were used.

Project description:Lines nearly isogenic for fw3.2 in the cultivated background Solanum lycopersicum c.v. Yellow Stuffer were grown in the greenhouse in a completely randomized design. fw3.2(ys) and fw3.2(wt) are NILs carrying cultivated and wild alleles for fw3.2 locus. Flowers were tagged a day before anthesis and self-pollinated at anthesis. Fruits at stage five, seven, and ten days post anthesis (dpa) were harvested. Pericarp and seed tissues were separately isolated. Four replicates were collected for each sample. RNA was extracted using Trizol and Stand-specific libraries were prepared from total RNA and sequences of 51 bp were generated on an Illumina HiSeq2000.

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.
