Responses of rice plant to multiple abiotic stresses revealed by transcriptome meta-analysis and identification of novel genetic factors.

ABSTRACT: Plant responses to abiotic stresses have a complex polygenic nature including main and epistatic genetic factors. Several tolerant rice varieties were subjected to drought, salt and cold stresses and their transcriptomic responses were evaluated using affymetrix probe set. Meta-analysis of standardized microarray data was conducted to identify specific and common genes responding to multiple abiotic stresses. 375 and 298 genes were up- and downregulated under drought stress, 281 and 313 genes were up- and downregulated under salt stress, and 1,273 and 2,996 genes were up- and downregulated under cold stress. In addition to many specific genes for each stress condition, common genes were identified for response to drought and salt (n=91), drought and cold (n=121), and salt and cold (n=108),
