ASK1 (MTR_5G082340) — Medicago truncatula

Summary

MtASK1 (MTR_5G082340) in barrel medic encodes a SKP1-like protein, a core component of SCF ubiquitin ligase complexes. The gene is associated with cullin family protein binding, auxin receptor activity, auxin binding, and MAPK phosphatase activity, among numerous other molecular functions. MtASK1 is linked to the regulation of organ growth, gibberellic acid signalling, auxin transport, DNA damage checkpoint, and the negative regulation of protein breakdown and cellulose anabolism. It is also associated with traits including seedling vigour, plant male sterility, bacterial disease response, bacterial blight resistance, drought tolerance, ABA sensitivity, and stalk, leaf, and flower morphology. The protein localises to the nuclear ubiquitin ligase complex, pollen tube, and male germ cell nucleus. Studies of related genes in other species link the SKP1 family to floral organ development, root gravitropism, photoperiodic flowering, and immunity.
