Analysis of TCP transcription factor in response to abiotic stress response

Abstract

Drought is the major environmental threat to agricultural production and distribution worldwide. Plant dehydration-stress adaptation is a complex biological process that involves global changes in gene expression and metabolite composition.
To discover novel master genes that regulate dehydration responsive pathway, we analyzed co-expressions of Arabidopsis genes using our dehydration-transcriptome data. We found 120 correlated-genes modules by co-expression analysis. In these modules, we analyzed gene-to-gene correlations of dehydration-repressed genes. Promoter analysis of these dehydration-repressed genes showed that Site II (GGNCCC) motifs were frequency found in their promoter regions. Site II is the predicted target sequence of TCP transcription factor. Now, we are analyzing an Arabidopsis stress-inducible TCP and its roles in abiotic stress response.
