Comprehensive Investigation of GRF Transcription Factors and Associated Responses to Drought Stress in Oat (<i>Avena sativa</i>).

ABSTRACT: Growth-regulating factors (GRFs) are plant-specific transcription factors that play important roles in plant growth and development. However, no systematic analysis of GRF genes has been reported in oat (Avena sativa). In this study, we conducted a comprehensive characterization of the GRF gene family in oat, including their physicochemical properties, chromosomal distribution, phylogenetic relationships, gene structure, conserved domains, promoter cis-elements, duplication events, and drought-responsive expression. In total, 28 GRF genes were identified in oat. Phylogenetic analysis classified them into two main groups, which could be further subdivided into five subgroups. Gene structure and conserved motif analyses revealed that AsGRF genes are
