Genome-Wide Analysis and Expression Profiles of AhCOLs Family in Peanut (<i>Arachis hypogaea</i> L.).

ABSTRACT: The CONSTANS-like (COL) gene family plays critical roles in plant growth, development, stress responses, and light signal transduction. However, its functions in peanut (Arachis hypogaea) remain poorly understood. In this study, we identified 18 AhCOL genes in the peanut genome, all localized in the nucleus. Phylogenetic analysis classified these genes into three subfamilies, with Group I containing eight members and Groups II and III each comprising five. Conserved domain analysis revealed that all AhCOL proteins possess at least one B-box and one CCT domain. Most of the AhCOL members in peanuts contain a large number of ABA and MeJA elements. Additionally, some members have low-temperature response elements, anaerobic induction, circadian control, and defense stress elements. Expression
