DCL3 — Brassica oleracea var. botrytis

Summary

BoDCL3, located on cauliflower chromosome 3, encodes a protein with RNase III, PAZ, and DEAD/DEAH-box helicase domains, and is annotated with ribonuclease III, helicase, DNA demethylase, and AP lyase activities. It is associated with siRNA, ta-siRNA, and pre-miRNA processing, RNA-directed DNA methylation, gene silencing, and post-transcriptional gene silencing. The gene is linked to leaf, root, stamen, and hypocotyl morphology traits, flowering time, seed development, viral disease response, herbicide sensitivity, osmotic and oxidative stress responses, salt tolerance, and root microbiota composition. It localizes to the nucleus, nucleolus, cytosol, D-body, and nuclear speck. Studies of related genes in other species connect the family to antiviral defense, DNA methylation patterning, phosphate homeostasis, transgenerational insect resistance, cold and salt stress tolerance, root elongation, and thermomorphogenesis.
