RDR6 — Camelina sativa

Summary

CsRDR6 (CSA09G052060) on Camelina sativa chromosome 9 encodes an RNA-dependent RNA polymerase with RdRP activity, RNA binding and ubiquitin ligase binding functions, and belongs to the RDR6 protein family. The gene is associated with posttranscriptional gene silencing by RNA, ta-siRNA and siRNA processing, antiviral response, defence response to bacteria, heat acclimation and response to heat, vegetative phase change, maintenance of shoot apical meristem identity, carpel and pistil development, pollen recognition, and wax anabolism. Its product localises to the cytoplasm, nucleus, endoplasmic reticulum, stress granules and the RNA-dependent RNA polymerase complex. CsRDR6 is associated with leaf morphology and composition traits, anthocyanin content, viral disease response and abiotic stress response traits, as well as phenotypes including leaf development and polarity, lateral root development, fertility, seed dormancy, antiviral defence, and trans-acting siRNA biogenesis. Related genes in other species are associated with virus resistance, Sclerotinia sclerotiorum resistance, self-incompatibility, and leaf morphology changes.
