SKP1 — Cicer arietinum

Summary

SKP1 on chickpea chromosome 5 encodes a protein containing SKP1-like and F-box domains, and is annotated with cullin family protein binding, auxin receptor activity, auxin binding, transcription factor binding, and ubiquitin-protein transferase activity. The gene is associated with protein ubiquitination, SCF complex assembly, jasmonic acid signaling, leaf development, organ growth, cell cycle regulation, and circadian rhythm. It has been linked to traits including leaf size, seedling vigor, lateral root length, photoperiod-sensitive flowering time, stomatal opening, root mass density, jasmonic acid content, and germination rate. Phenotypic associations include osmotic stress response, plant immunity, cold tolerance, virus resistance, seed vigor, shade avoidance, and auxin responsiveness. Studies of related genes in other species link the family to photoperiodic flowering time control, floral organ development, root gravitropism, and fungal resistance.
