Characterization of WRKY co-regulatory networks in rice and Arabidopsis.

ABSTRACT:

Background

The WRKY transcription factor gene family has a very ancient origin and has undergone extensive duplications in the plant kingdom. Several studies have pointed out their involvement in a range of biological processes, revealing that a large number of WRKY genes are transcriptionally regulated under conditions of biotic and/or abiotic stress. To investigate the existence of WRKY co-regulatory networks in plants, a whole gene family WRKYs expression study was carried out in rice (Oryza sativa). This analysis was extended to Arabidopsis thaliana taking advantage of an extensive repository of gene expression data.

Results

The presented results suggested that 24 members of the rice WRKY gene family (22% of the total) were differentially-regulated in response to at leas
