VIR — Brassica oleracea var. botrytis

Summary

BoVIR, encoded by the cauliflower gene BOLND125_C03P042980.1_BOLND125_V1 on chromosome 3, is a Virilizer family protein containing VIR_N, NB-ARC, TIR, BTB/POZ, and LRR domains, and exhibits mRNA methyltransferase, NADP nucleosidase, DPNase, ADP-ribosyl cyclase/cyclic ADP-ribose hydrolase, and ADP/ATP binding activities. It is associated with RNA methylation, mRNA processing, photoprotection, NAD breakdown, defense responses to other organisms and fungi, antiviral response, upregulation of programmed cell death, hypersensitive response, embryo development, salinity response, and signal transduction. The protein localizes to the nucleus, cytoplasm, plasmalemma, nuclear speck, and WMM complex. It has been linked to vascular formation, salt stress tolerance, and photosynthetic efficiency. Related genes in other species connect the family to root cap formation, gravity response, and lateral root development.
