CF1 — Daucus carota subsp. sativus

Summary

DCAR_003284 (DcCF1) on carrot chromosome 1 encodes a dynamin family GTPase with a GTP-binding domain, pleckstrin homology domain, and dynamin stalk and GED domains. The gene product exhibits GTPase activity, clathrin binding, microtubule binding, and protein binding. DcCF1 is associated with regulation of endocytosis, cytokinesis via cell plate formation, phragmoplast microtubule organization, cell polarization, trichome branching, root hair initiation, stigma development, and vascular tissue pattern formation. It localizes to clathrin-coated vesicles, the cell plate, microtubules, and the Golgi medial cisterna. The gene has been connected to traits including relative root length, seed set percent, nitrate uptake, pollen fertility restoration, arsenic concentration, leaf composition, seedling growth, disease tolerance, and root morphology. Studies of related genes in other species link the dynamin family to plant immunity, pathogen resistance, pectin biosynthesis, and organ size.
