Research Progresses on WOX Family Genes in Regulating Plant Development and Abiotic Stress Response

doi:10.13560/j.cnki.biotech.bull.1985.2022-1098

Abstract

Abstract:

The WOX（WUSCHEL-related homeobox）proteins comprise a plant-specific transcription factor family, which contain a DNA-binding homeodomain（HD）consisting of 65-66 amino acid residues. WOX family members are involved in important biological processes such as plant growth and development and responses to abiotic stress by regulating the expressions of target genes at the transcriptional level. This article reviews the classification and structural characteristics of plant WOX family members, and focusing on the functional research progress in the regulation of plant growth and development（such as root, stem, leaf, flower, fruit, seed, and embryo）and plant responses to abiotic（including drought, salt, and cold）stresses. The significance of studying of WOX transcription factors and the issues to be solved are also prospected, aiming to provide a reference for further research on the function of WOX family genes.

Key words: transcription factors, WOX, growth and development, abiotic stress
