SK3 — Medicago truncatula

Summary

MTR_4G032470 (MtSK3, also known as SK3 or ASK3) on barrel medic chromosome 4 encodes a SKP1-like protein, a component of the SKP1/BTB/POZ superfamily, and is associated with cullin family protein binding, auxin receptor activity, auxin binding, IP6 binding, transcription factor binding, ubiquitin-protein transferase activity, and protein binding. The gene is associated with SCF complex assembly, regulation of gibberellic acid-mediated signaling, negative regulation of cellulose anabolism, gene silencing by miRNA, seed dormancy, regulation of photomorphogenesis, regulation of circadian rhythm, and phloem or xylem histogenesis. It is linked to yield, seedling vigor, leaf and vein morphology, oleic acid content, anthocyanin content, auxin sensitivity, photoperiod-sensitive flowering time, and herbicide sensitivity. Studies of related genes in other species connect the SKP1-like family to far-red light signaling, flowering, lateral root development, and fungal resistance.
