Genome-wide identification and expression analysis of HD-ZIP gene family in sunflower (Helianthus annuus L.) under water deficit stress.

ABSTRACT: The HD-ZIP gene family plays a crucial role in plant growth, development, and responses to environmental stressors. Nevertheless, there exists a paucity of information regarding this gene family in Helianthus annuus (Sunflower). In the present investigation, a total of 55 putative HaHD-ZIP genes were identified and subsequently classified into four subfamilies based on phylogenetic analysis, further substantiated through the analysis of gene structures and conserved motifs. An analysis of the promoter regions of HaHD-ZIP genes revealed the existence of numerous diverse cis-regulatory elements. Furthermore, we identified 15,577 binding sites for the HD-ZIP transcription factor within the sunflower genome, distributed across 9,479 unique genes. The analysis of protein-protein interactions el
