Genome-wide identification of the WRKY transcription factors family and regulation of metabolites under cold stress in Astragalus membranaceus.

ABSTRACT:

Background

WRKY transcription factors (TFs) are important transcriptional regulators in plants, with their members widely involved in plant growth and development as well as responses to abiotic stresses. However, researches on WRKY genes in the medicinal plant A. membranaceus are scarce. Specifically, the roles of AmWRKYs in cold stress adaptation and their regulatory effects on flavonoid biosynthesis, which determines both medicinal quality and stress resistance, remain largely unexplored. Given its high economic value and extreme sensitivity to cold in its main cultivation regions, identifying key regulators of its cold tolerance is crucial for genetic improvement.

Result

In this study, 94 AmWRKY were identified based on genome analysis, distributed across 8 chromosomes.
