SR1 — Brassica oleracea var. botrytis

Summary

BoSR1 (SR1, also known as CIPK14, PKS24, SNRK3.15) on cauliflower chromosome 2 encodes a protein with a NAF/FISL domain and a serine/threonine kinase domain, and is annotated with protein serine kinase activity, calcium ion binding, and nucleoside diphosphate kinase activity. The gene is associated with a wide range of biological processes including potassium ion import and homeostasis, calcium signaling, regulation of abscisic acid anabolism, photomorphogenesis, response to UV, hydrogen peroxide, and glucose, as well as chloroplast accumulation movement and mRNA splicing. It is linked to numerous traits such as seed size, days to flowering, root hair length, stomatal opening and closure, and responses to high and low temperature, oxidative stress, and disease. Localisation evidence connects the product to the thylakoid, tonoplast, vacuole, chloroplast envelope, and plant-type cell wall. Related genes in other species link the family to pathogen resistance, immune response, salicylic acid accumulation, glucosinolate metabolism, and multiple stress responses.
