CAF — Daucus carota subsp. sativus

Summary

DcCAF (DCAR_022119) on carrot chromosome 6 encodes a protein with domains characteristic of Dicer-like ribonucleases, including RNase III, PAZ, dsRBD, and DEAD/DEAH-box helicase domains, and exhibits ribonuclease III activity, dsRNA binding, helicase activity, and miRNA binding. The gene is associated with small RNA processing pathways, including LsiRNA, pre-miRNA, pri-miRNA, and ta-siRNA processing, as well as gene silencing by miRNA, mRNA cleavage, and regulation of adaxial/abaxial pattern formation. In carrot, DcCAF is linked to soluble sugar content. Broader associations include adult leaf, floral organ, and leaf margin morphology traits, vegetative vigor, viral disease response, herbicide sensitivity, osmotic response, root mass density, and meristem identity. The gene is also connected to jasmonic acid-isoleucine accumulation, herbivore resistance, and resistance to Fusarium brachygibbosum.
