RDR1 — Cucumis sativus
Summary
CsRDR1 (CSA_5G239140) on cucumber chromosome 5 encodes an RNA-dependent RNA polymerase (EC 2.7.7.48) with RdRP activity and RNA binding, belonging to the RDR1/2-like family. It is associated with positive regulation of posttranscriptional gene silencing, posttranscriptional gene silencing by RNA, siRNA processing, maintenance of shoot apical meristem identity, wax anabolism, hypersensitivity, phenylpropanoid anabolism, response to virus, response to salicylate, and GO:0032259 and GO:0015979. The gene is linked to cuticular wax biosynthesis, antiviral defense, viral resistance, antiviral immunity, resistance to Sclerotinia sclerotiorum, resistance to Fusarium brachygibbosum, herbivore resistance, and drought resistance. Localization evidence places the product in the nucleus and the RNA-directed RNA polymerase complex. Related genes in other species link the family to virus-derived small interfering RNA biogenesis, pathogen defense, and salicylic acid response.
