Project description:RNA sequencing in tomato for detect mRNA expression of Solanum lycopersicum flower.The two cultivars (monomaker, raceme) had three different flowering stages (budlet, Flower bud, Full bloom) for transcriptome sequencing
Project description:The tomato SlWRKY3 transcription factor was overexpressed in cultivated tomato (Solanum lycopersicum)and transgenic plants transcriptome was compared to that of wild-type plants.

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: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: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:RNA interference (RNAi) is a widely-used approach to generate virus-resistant transgenic crops. However, durability of RNAi-mediated resistance under extreme field conditions and side-effects of stable RNAi expression have not been thoroughly investigated. Here we performed field trials and molecular characterization of two RNAi-transgenic Solanum lycopersicum lines resistant to Tomato yellow leaf curl virus (TYLCV) disease, the major constraint for tomato cultivation in Cuba and worldwide. In order to determine potential impact of the hairpin RNA transgene expression on tomato genome expression and development, differences in the phenotypes and the transcriptome profiles between the transgenic and non-transgenic plants were examined. Transcriptome profiling revealed a common set of up- and down-regulated tomato genes, which correlated with slight developmental abnormalities in both transgenic lines.
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.
