Grapevine WRKY transcription factors

Abstract

Grape is one of the most economically important fruits and is cultivated worldwide, but the viticulture faces challenges of various biotic and abiotic stresses. WRKY transcription factors play important roles in regulating plant responses to these stresses, in addition to their roles in plant growth. Genome-wide identification and functional analysis of grape WRKY family genes have been conducted in recent years. However, different approaches were found in naming the grape WRKY family gene members among these reports, which causes a great deal of confusion and has become a barrier in the sharing of research findings in the research community. Here we attempt to comprehensively review the research progress on grape WRKY family transcription factors, and attempt to assign unified names for them.
