CHC1 — Daucus carota subsp. sativus

Summary

DCAR_028582 (DcCHC1) on carrot chromosome 8 encodes a clathrin heavy chain protein. The product possesses clathrin, phospholipid, ubiquitin, SNARE and steroid binding activities, along with structural molecule activity, and is associated with receptor-mediated endocytosis, clathrin-mediated endocytosis, and protein positioning. DcCHC1 is linked to leaf abscission, anther wall tapetum cell differentiation, pollen exine formation, negative regulation of leaf senescence and the hypersensitive response, defence against Gram-negative bacteria, induced systemic resistance, and viral spread. It is associated with numerous traits including brassinosteroid and gibberellin content, bacterial disease and insect damage responses, temperature stress response, self-incompatibility, pollen fertility restoration, fruit growth, root mass density, leaf trichome density and shape, seedling hypocotyl length, and phototropism response. Related genes in other species are associated with floral organ abscission, plant immunity, salt resistance, thermotolerance, and gibberellin biosynthesis.
