SKP1 — Triticum aestivum

Summary

TRAESCS5B02G282400 (symbol SKP1) on bread wheat chromosome 5B encodes an uncharacterized protein containing an SKP1 component dimerisation domain and a SKP1/BTB/POZ superfamily domain. The gene product is associated with cullin family protein binding and is linked to ubiquitin-dependent proteolysis, protein ubiquitination, and SCF-dependent proteasomal ubiquitin-dependent protein breakdown. It has been associated with hormone metabolism, JA signaling, defense response, embryogenesis, protein synthesis, and secondary metabolism, and localises to both the cytoplasm and nucleus. SKP1 is associated with common bunt spike incidence, grain density, grain number per plant, grain weight per spike, grain yield per plant, grains per spike, days to heading, spike length, water use efficiency, grain number, grain size, GRWT, grain weight, anthesis time, plant height, grain yield, drought tolerance, common bunt, and test weight. Related genes in other species, such as rice OSK1 and OSK20, are linked by sequence similarity.
