CAF — Daucus carota subsp. sativus

Summary

DcCAF (DCAR_012419) on carrot chromosome 3 encodes a protein with ribonuclease III activity, helicase activity, and multiple nucleic-acid binding functions, and contains Dicer dimerisation and DEAD/DEAH-box helicase domains. In carrot, the gene is associated with soluble sugar content. Annotated associations link DcCAF to LsiRNA processing, pre-miRNA processing, pri-miRNA processing, ta-siRNA processing, gene silencing by miRNA-directed mRNA cleavage, regulation of adaxial/abaxial pattern formation, regulation of seed maturation, and embryonic pattern specification. The gene is further associated with traits including leaf, floral organ and inflorescence morphology, vegetative vigor, viral disease response, herbicide sensitivity, root mass density, seed dormancy, and sugar content. Studies of related genes in other species link the family to antiviral defence, systemic RNA interference, herbivore resistance, and resistance to Sclerotinia sclerotiorum.
