Transcriptome analysis and genome-wide identification of WRKY gene family in Leonurus japonicus under drought stress.

ABSTRACT:

Background

Leonurus japonicus (L. japonicus) is a herbaceous flowering plant, widely distributed in Asia. Drought is one of the primary environmental stress factors affecting L. japonicus growth. Previous studies have demonstrated that WRKY transcription factors (TFs) play a crucial role in plant responses to drought stress. So far, there has been no research on the function of WRKY genes in L. japonicus.

Results

The physiological experiment results showed that drought stress significantly increased the malondialdehyde (MDA), proline, and hydrogen peroxide (H₂O₂) content of L. japonicus. Transcriptome analysis revealed significant changes in the expression levels of the WRKY gene family. Based on bioinformatics analysis, 67 WRKY genes (LjWRKYs) were identified in the genome
