Solanum lycopersicum Transcriptome or Gene expression

ABSTRACT: 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. Young flower buds were harvested. For each sample, three replicates were used. 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.

INSTRUMENT(S): Illumina HiSeq 2000

Domestication of crop plants had effects on human lifestyle and agriculture. However, little is known about the underlying molecular mechanisms accompanying the changes in fruit appearance as a consequence of selection by early farmers. We report the fine mapping and cloning of a tomato (Solanum lycopersicum) fruit mass gene encoding the ortholog of KLUH, SlKLUH, a P450 enzyme of the CYP78A subfamily. The increase in fruit mass is predominantly the result of enlarged pericarp and septum tissues ...[more]

Project description:Phosphorus (P) is an essential macronutrient for plant growth and development, and a plant must balance P uptake, mobilisation, and partitioning to various organs to modulate P homeostasis. The underlying molecular mechanisms of wheat under phosphate (Pi) starvation conditions remain elusive despite wheat is an important cultivated food crop worldwide. We generated transcriptome profiles of wheat variety Chinese Spring (CS) in response to Pi starvation (-P) for 10 days using RNA-Seq methods.We used 73.8 million high-quality reads obtained from libraries for de novo assembly. Overall, a set containing 29,617 non-redundant wheat transcripts was constructed with 15,047 assemblies and 14,570 non-redundant, full-length cDNAs in TriFLDB. Of the transcripts, 10,656 of the 15,047 assemblies were unaligned against barley full-length cDNAs, suggesting that many of them might be distinct of barley transcripts. The distribution of average expression levels for the assembly was lower than that for cDNAs, suggesting that the assemblies contained rare transcripts limited availability using full-length cDNA library construction methods. Within the transcript set, we identified 892-2,833 up- or downregulated transcripts in root and shoot, including 18.9-40.5% assemblies, uncovered by cDNAs in TriFLDB under -P in each condition. In the results, the expression level of wheat IPS1 (induced by phosphate starvation 1) homolog, TaIPS1, was 358.6-fold higher in the root and 12.6-fold higher in the shoot, which was confirmed by qRT-PCR analysis. Comparative analysis between wheat (a rice orthologue) and rice responsive transcripts under -P conditions showed that 39 (root) and 21 (shoot) responsive transcripts were commonly upregulated, and most of them seemed to be involved in a general response to -P; IPS1-mediated signal transduction and its downstream function such as Pi remobilization, Pi uptake and change metabolism.Our transcriptome profiling demonstrates the impact of -P in wheat. This study shows that enhancing the Pi-mediated signalling pathway through IPS1 is conserved as a potent adaptation to Pi starvation in both wheat and rice, and also that our constructed strategy using short read next generation sequencing (NGS) data was successful for the transcriptome analysis in wheat without reference genome. 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.
