DMS2 — Brassica oleracea var. botrytis

Summary

BoDMS2 (BOLND125_C05P052140.1_BOLND125_V1) on cauliflower chromosome 5 encodes a DNA-directed RNA polymerase subunit beta, containing RNA polymerase Rpb2 and DNA-directed RNA polymerase subunit 2 domains, with DNA-directed RNA polymerase activity, chromatin binding, and ATP-dependent chromatin remodeler activity. The gene is associated with RNA-directed DNA methylation (RdDM), siRNA processing, posttranscriptional gene silencing, heterochromatin organization, and epigenetic regulation of gene expression. It localizes to RNA polymerase IV and V complexes, heterochromatin, and nuclear bodies. BoDMS2 is associated with Meloidogyne incognita resistance, disease tolerance, leaf senescence, seed viability, root morphology, and salt tolerance. It is also linked to heat tolerance, transposon suppression, and DNA methylation. Related genes in other species are linked to transgenerational insect resistance, self-incompatibility, and Agrobacterium-mediated transformation efficiency.
