SIP3 — Brassica napus

Summary

BnSIP3 (also known as BnCIPK6, BnSNRK3.14) on chromosome C01 of oilseed rape encodes a protein with a NAF/FISL domain and a serine/threonine kinase domain, annotated with calcium-dependent protein serine/threonine phosphatase activity, protein serine kinase activity, and calcium ion binding. The gene is associated with nitrogen utilization, fatty acid breakdown, downregulation of seed dormancy, response to water, potassium ion import, basipetal auxin transport, and organogenesis. It is linked to traits including net photosynthetic rate, transpiration rate, stomatal resistance, leaf number, days to flowering, root hair length, magnesium and potassium sensitivity, and water stress response. Related genes in other species are associated with potassium acquisition, salt tolerance, lateral root development, disease resistance, and pollen germination.
