Identification of WRKY transcription factors in Ipomoea pes-caprae and functional role of IpWRKY16 in sweet potato salt stress response.

ABSTRACT:

Background

WRKY transcription factors are plant-specific and play essential roles in growth, development, and stress responses, including reactions to salt, drought, and cold. Despite their significance, the WRKY genes in the wild sweet potato ancestor, Ipomoea pes-caprae, remain unexplored.

Results

In this study, 65 WRKY genes were identified in the I. pes-caprae transcriptomic data. A phylogenetic tree incorporating Arabidopsis thaliana and Ipomoea batatas revealed seven major groups, each characterized by conserved gene structural features. Transcriptome data of I. pes-caprae under salt stress conditions identified 17 highly expressed WRKY genes, whose promoter regions contain cis-acting elements associated with plant growth, stress responses, and hormone signaling.
