Genome-Wide Analysis of the <i>12-Oxo-Phytodienoic Acid Reductase</i> Gene Family in Peanut and Functional Characterization of <i>AhOPR6</i> in Salt Stress.

ABSTRACT: 12-oxo-phytodienoic acid reductases (OPRs) have been substantiated as pivotal in plant growth and response to biotic and abiotic stresses. However, the functional characterization of OPR genes in the peanut genome remains limited. In this study, we identified a total of 20 OPR genes in a tetraploid cultivar and two diploid peanut species, categorizing them into two subfamilies, OPRI and OPRII. The gene structure and conserved protein motifs within each subfamily were elucidated. Additionally, our findings indicate an uneven chromosomal distribution of peanut OPR genes. Gene duplication events were identified as pivotal in the expansion of the OPR gene family. An analysis of cis-acting elements within OPR gene promoters revealed the presence of nume
