SKP1 — Beta vulgaris subsp. vulgaris

Summary

BVRB_2G035550 (SKP1) on sugar beet chromosome 2 encodes a SKP1-like protein containing a Skp1 component dimerisation domain and a POZ domain, and is annotated with multiple molecular functions including cullin family protein binding, auxin receptor activity, and MAPK phosphatase activity. The gene is associated with SCF complex assembly, regulation of gibberellic acid-mediated signalling, negative regulation of cytokinin signalling, and photoentrainment of the circadian clock. It has been linked to traits including seedling vigour, submergence tolerance, bacterial blight disease resistance, plant male sterility, photoperiod-sensitive flowering time, seed oil content, and drought tolerance. The gene is also associated with heat and cold stress tolerance, reactive oxygen species homeostasis, and organ growth. Studies of related genes in other species link the SKP1 family to immunity, floral organ development, jasmonate perception, and far-red light signalling.
