Comprehensive genome-wide analysis of ARF transcription factors in orchardgrass (Dactylis glomerata): the positive regulatory role of DgARF7 in drought resistance.

ABSTRACT: Auxin response factor (ARF), a transcription factor, is crucial in controlling growth, development, and response to environmental stress. Orchardgrass (Dactylis glomerata) is an economically significant, widely cultivated forage grass. However, information on the genome-wide information and functional characterization of ARFs in orchardgrass is limited. This study identified 27 ARF genes based on the orchardgrass genome database. These DgARFs were unevenly distributed across the seven orchardgrass chromosomes and clustered into four classes. Phylogenetic analysis with multispecies of ARF proteins indicated that the ARFs exhibit a relatively conserved evolutionary path. Focusing on hormone signaling responses, DgARF7 demonstrated a potential positive regulatory role in response to 3-indole
