Genome-wide identification and expression profiling of WRKY gene family in grain Amaranth (Amaranthus hypochondriacus L.) under salinity and drought stresses.

ABSTRACT:

Background

The WRKY gene family plays a significant role in plant growth, development, and responses to biotic and abiotic stresses. However, the role of the WRKY gene family has not been reported in Amaranthus hypochondriacus. This study presents a comprehensive genome-wide analysis of the WRKY gene family in grain amaranth (A. hypochondriacus L.), a resilient crop known for its high nutritional value and adaptability to challenging environments.

Results

In this study, 55 WRKY genes (AhyWRKY1-55) were identified in A. hypochondriacus and distributed unevenly across 16 scaffolds. Of these, 50 contained conserved WRKY domains and were classified into three main groups. Group II was further divided into five subgroups (IIa-IIe) based on phylogenetic analysis, with each clade b
