Multifunctional activities of ERF109 as affected by salt stress in Arabidopsis.

ABSTRACT: Transcriptomic analysis was conducted in leaves of Arabidopsis T-DNA insertion ERF109-knocked out (KO) mutant or plants overexpressing (OE) the gene to detect its role in driving expression of programmed cell death- (PCD-) or growth-related genes under high salt (200 mM NaCl) stress. The analysis yielded ~22-24 million reads, of which 90% mapped to the Arabidopsis reference nuclear genome. Hierarchical cluster analysis of gene expression and principal component analysis (PCA) successfully separated transcriptomes of the two stress time points. Analysis indicated the occurrence of 65 clusters of gene expression with transcripts of four clusters differed at the genotype (e.g., WT (wild type), KO ERF109 or OE ERF109 ) level. Regulated transcripts involved DIAP1-like gene encoding a death-asso
