Natural variation of transcriptional networks in Arabidopsis thaliana in response to salt stress

ABSTRACT: Arabidopsis ecotypes of Sha and Ler showed differences in tolerance to salinity stress. A previous study indicated that a premature stop codon resulting in a truncated Response to ABA and Salt 1 (RAS1) protein in Sha contributes to the increased salt tolerance relative to Ler ecotype. Sha exhibited higher germination rates and longer roots on MS plate, presumably due to the decreased ABA sensitivity in Sha. More Sha plants also survived in soil after salt treatment with relatively lower electrolyte leakage when compared to Ler. Transcriptome analysis revealed that expression levels of many genes were changed between Sha and Ler ecotypes and by salt treatments. About 500 transcripts were commonly changed by at least one salinity effect and one ecotype effect, and 171 of them were co-regulat
