SKP1 — triticum aestivum

Summary

TRAESCS6D02G001600 (symbol SKP1, also known as TSK1) on bread wheat chromosome 6D encodes a SKP1-like protein containing Skp1_comp_POZ and Skp1_comp_dimer domains. The product binds cullin family proteins and is associated with protein ubiquitination, protein processing, protein stabilization, and protein oligomerization. It is linked to jasmonic acid signaling, stomatal opening and closure, response to freezing, innate immunity, and meiosis. The gene is associated with grain yield, grain weight, grain number, grain protein content, starch content, chlorophyll content, stem rust, stripe rust, drought tolerance, salt tolerance, seed dormancy, and grain filling period. It localizes to the cytoplasm and nucleus. Studies of related genes in other species link the SKP1 family to seed germination and auxin response.
