Project description:UV radiation is a ubiquitous component of solar radiation that affects plant growth and development. Analysis of natural variation in response to UV radiation revealed significant differences among natural accessions of Arabidopsis thaliana. However, the genetic basis of this is to a large extent unknown. Here, we analyzed the response of Arabidopsis accessions to UV radiation stress by performing RNA-sequencing of three UV sensitive and three UV resistant accessions. The genome-wide transcriptional analysis revealed a large number of genes significantly up- or down-regulated only in sensitive or only in resistant accessions, respectively. Mutant analysis of few selected candidate genes suggested by the RNA-sequencing results indicate a connection between UV radiation stress and plant-pathogen-like defense responses.

Project description:These data provide a basis for the detection of sequence based polymorphisms between 10 Spring annual accessions of Arabidopsis thaliana. The experimental data provides an initial characterization of differences among the accessions, as well as a means for improving gene expression studies with the filtering of SFP from arrays studies. Recent studies have documented remarkable genetic variation among Arabidopsis thaliana accessions collected from diverse habitats and across its geographical range. Of particular interest are accessions with putatively locally adapted phenotypes – i.e., accessions with attributes that are likely adaptive under the climatic or habitat conditions of their sites of origin. These genotypes are especially valuable as they may provide insight into the genetic basis of adaptive evolution as well as allow the discovery of genes of ecological importance. The gene expression studies were conducted under two levels of soil moisture and accompanied by physiological measurements to characterize early responses to soil moisture deficit.
