Project description:Our analysis provides a comprehensive picture of how P. trichocarpa responds to drought stress at physiological and transcriptome levels which may help to understand molecular mechanisms associated with drought response and could be useful for genetic engineering of woody plants. Drought stress treatment was performed dividing P. trichocarpa plants into the well-watered (WW) group (soil volumetric water content of 40â45 %) and the water-limited group (soil volumetric water content of 10â15 %). Two cDNA libraries constructed separately from the WW and WL groups were subjected to high-throughput Illumina sequencing.

Project description:Effect of low-doses of ionizing radiation on the behaviour of epithelial cells. The aim of the study is to check whether a single exposure of 50 mGy of ioninzing radiation promotes changes in RNA transcription levels and/or mutations.
Project description:The Arabidopsis Branching Enzyme 1 (BE1) gene encodes a putative glycoside hydrolase involved in carbohydrate metabolism. A partial loss-of-function mutation of the BE1 gene (be1-3 mutant) severely impaired adventitious shoot formation and somatic embryogenesis but not root formation in tissue culture. To gain a better understanding of the molecular mechanism underlying the in vitro plant regeneration defects caused by the BE1 gene mutation, we performed RNA sequencing analysis (RNA-seq) to examine the differential gene expression between WS and be1-3 mutant at dedifferentiation and redifferentiation stages.
Project description:The concurrent epigenetic changes during this period of remarkable improvement in maize grain yield remain unknown. Here, we performed MethylC-seq and RNA-seq on 4 related inbred lines with known pedigree information. Analysis of epigenetic changes over the course of historical maize breeding is a valuable new avenue in the exploration for crop improvement. These data lead us to suggest that novel epihaplotypes, in addition to DNA variation, are a substrate of selection during breeding, and that epigenetic variation between parents may also contribute to heterosis in hybrids.

Project description:Maize exhibits levels of structural variation (SV) of non-repeat sequences that are unprecedented among higher eukaryotes. This SV includes hundreds of copy number variants (CNVs) and thousands of presence/absence variants (PAVs). Many of the PAVs contain intact, expressed, single-copy genes that are present in one haplotype but absent from another. The goal of this project is to test the hypothesis that differences in gene copy number (both gains and losses) contribute to the extraordinary phenotypic diversity and plasticity of maize. Maize is a good model for these studies because it exhibits a rapid decay of linkage disequilibrium (LD) and because a draft genome sequence of the B73 inbred and mapping populations are available. As a first step, the Zeanome, a near-complete set of genes present in B73, other maize lines and the wild ancestor of maize (teosinte), is being defined using transcriptomic data. Note: All samples in SRA were assigned the same sample accession (SRS302561). This is incorrect as there are different samples, hence âSource Nameâ was replaced with new values. Comment[ENA_SAMPLE] contains the original SRA sample accessions.
