Genome-Wide Identification of <i>PP2C</i> Gene Family in Oat (<i>Avena sativa</i> L.) and Its Functional Analyses in Response to ABA and Abiotic Stresses.

ABSTRACT: Plant protein phosphatase 2C (PP2C) represents the largest and most functionally diverse group of protein phosphatases in plants, playing pivotal roles in regulating metabolic processes, hormone signaling, stress responses, and growth regulation. Despite its significance, a comprehensive genome-wide analysis of the PP2C gene family in oat (Avena sativa L.) has remained unexplored. Leveraging the recently published oat genome, we identified 194 AsaPP2C genes, which were unevenly distributed across all 21 chromosomes. A phylogenetic analysis of PP2C classified these genes into 13 distinct subfamilies (A-L), with conserved motif compositions and exon-intron structures within each subfamily, suggesting evolutionary functional specialization. Notably, a promoter anal
