High light intensity plays a major role in emergence of population level variation in Arabidopsis thaliana along an altitudinal gradient.

摘要: Environmental conditions play an important role in the emergence of genetic variations natural populations. We identified genome-wide patterns nucleotide coding regions Arabidopsis thaliana These populations originated from 700 m to 3400 m a.m.s.l. Western Himalaya. Using a pooled RNA-Seq approach, we local and global level population-specific SNPs. The biological functions SNP-containing genes were primarily related high light intensity prevalent at high-altitude regions. novel SNPs these might have arisen de novo In another FSTs correlated with corresponding climatic factors. ‘Radiation growing season’ was only environmental factor found be strongly gene-level FSTs. both approaches, as primary abiotic stress associated differential gene expression analysis between field controlled condition grown plants also showed stress, particularly for altitude Our results provide perspective along altitudinal gradient their putative variations.
