SKP1 — Capsicum annuum

Summary

T459_32156 (SKP1) in pepper (Capsicum annuum, chromosome PGAv.1.6.scaffold588) encodes a protein containing SKP1-like and Skp1 component dimerisation domains, and is annotated with diverse molecular functions including cullin family protein binding, auxin receptor activity, MAPK phosphatase activity, and DNA transmethylase activity. The gene is associated with SCF complex assembly, regulation of gibberellic acid-mediated signalling, negative regulation of cytokinin signalling, acropetal auxin transport, and photoentrainment of the circadian clock. It is linked to traits including bacterial blight disease resistance, submergence tolerance, photoperiod-sensitive flowering time, plant male sterility, seedling vigor, root hair density, oleic acid content, and starch grain synthesis. Studies of related genes in other species connect the SKP1 family to floral organ development, male sterility, jasmonate perception, and defence against necrotrophic pathogens.
