Comprehensive analysis of AHL gene family and their expression under drought stress and ABA treatment in Populus trichocarpa.

ABSTRACT: The AT-hook motif nuclear-localized (AHL) family is a plant transcription factor family, which plays an important role in growth and development and stress responses. We identified and analyzed 37 AHL genes in poplar (Populus trichocarpa). Phylogenetic analysis classified the PtrAHL members into three subfamilies based on their conserved domain. All PtrAHL paralogous pairs evolved under purifying selection. The promoter analysis revealed the presence of stress-related and phytohormone-related cis-elements of the PtrAHL genes. Our analysis of the tissue-specific expression pattern of PtrAHL genes indicated their significance in tissue and organ development. Network-based prediction suggested that PtrAHL genes may interact with histone
