CYC1 — Daucus carota subsp. sativus

Summary

DCAR_031609 (CYC1) in carrot (Daucus carota subsp. sativus) on chromosome DCARv2_B18 encodes a cyclin A/B-like protein with cyclin-box and cyclin N/C domains, and is annotated with cyclin-dependent protein serine/threonine kinase regulator activity, histone acetylase activity, SUMO transferase activity, and kinase binding. The gene is associated with mitotic cell cycle phase transition, G1/S transition, regulation of meiotic nuclear division, asymmetric cell division, gamete generation, and upregulation of DNA endoreduplication and cell proliferation. It localizes to the CDK holoenzyme, cyclosome, preprophase band, and nucleus. Associations include plant cell size, biomass yield, leaf trichome density, flower and inflorescence development traits, cytokinin and brassinosteroid sensitivity, anthocyanin content, and biotic stress responses. Related genes in other species link the family to cell cycle control, root meristem size, seed yield, and nematode resistance.
