A CW-type zinc finger protein is involved in RES-oxylipin signaling and the response to abiotic stress in <i>Arabidopsis thaliana</i>.

ABSTRACT:

Introduction

Oxylipins regulate the response of plants to biotic and abiotic stress factors and the tolerance of unfavorable conditions. While the signaling pathway of jasmonic acid has been intensively studied, little is known about the signal transduction that mediates the responses of reactive electrophile oxylipins such as 12-oxo phytodienoic acid and prostaglandins.

Methods and results

Here, a CW-type zinc finger protein (ZIFI1, At3g62900) was identified as a new signaling factor in a mutant screen. Transcriptome analysis of Arabidopsis mutants with a defect in this gene showed that the zinc finger protein is involved in regulating gene expression. Only about half (327 genes) of the about 646 genes induced by the reactive electrophilic oxylipin prostaglandin in t
