Project description:Metal tolerance is often a result of metal storage or distribution. Thus, with the goal of advancing the molecular understanding of such metal homeostatic mechanisms, natural variation of metal tolerance in Arabidopsis thaliana was investigated. Substantial variation exists in tolerance of excess copper (Cu), zinc (Zn) and cadmium (Cd). Two accessions, Col-0 and Bur-0, and a recombinant inbred line (RIL) population derived from these parents were chosen for further analysis of Cd and Zn tolerance variation, which is evident at different plant ages in various experimental systems and appears to be genetically linked. Three QTLs, explaining in total nearly 50 % of the variation in Cd tolerance, were mapped. The one obvious candidate gene in the mapped intervals, HMA3, is unlikely to contribute to the variation. In order to identify additional candidate genes the Cd responses of Col-0 and Bur-0 were compared at the transcriptome level. The sustained common Cd response of the two accessions was dominated by processes implicated in plant pathogen defense. Accession-specific differences suggested a more efficient activation of acclimative responses as underlying the higher Cd tolerance of Bur-0. The second hypothesis derived from the physiological characterization of the accessions is a reduced Cd accumulation in Bur-0. The microarray analysis was used to identify candidate genes for Cd-tolerance and -accumulation differences between the accessions Bur-0 and Col-0 as well as to analyse the expressional response of A.thaliana to Cd-stress.

Project description:Alternative splicing (AS) plays key roles in plant development and responses to environmental changes. However, the mechanisms underlying AS divergence (differential expression of transcript isoforms resulting from alternative splicing) in plant accessions and its contributions to responses to environmental stimuli remain unclear. In this study, we investigated genome-wide variation of AS in Arabidopsis thaliana accessions Col-0, Bur-0, C24, Kro-0, and Ler-1, as well as their F1 hybrids, and characterized the regulatory mechanisms for AS divergence by RNA sequencing (RNA-seq). We found that most of the divergent AS events in Arabidopsis accessions were cis-regulated by sequence variation, including those in core splice site and splicing motifs. Many genes that differed in AS between Col-0 and Bur-0 were involved in stimulus responses. Further genome-wide association analyses of 22 environmental variables showed that SNPs influencing known splice site strength were also associated with environmental stress responses. These results demonstrate that cis-variation in genomic sequences among Arabidopsis accessions was the dominant contributor to AS divergence, and it may contribute to differences in environmental responses among Arabidopsis accessions.

Project description:We produced RNA-Seq reads from messenger RNA isolated from seedling, root, and floral bud tissue for 17 MAGIC founder accessions (inbred strains) of Arabidopsis thaliana (see Gan et al. 2011. Nature, 477:419-23 for a description of the MAGIC genetic mapping resource). The resulting RNA-Seq data provide a resource to assess tissue-specific expression across different accessions of A. thaliana. Note that comparable read data for accessions Col-0 and Can-0, which are also founders of the MAGIC lines, has previously been released under GEO series GSE30795 (Gan et al. 2011. Nature, 477:419-23).
