NIT1 — Brassica napus

Summary

BnNIT1 (DARMORV10_A06P22060.1) on chromosome A06 of oilseed rape encodes a nitrilase family protein with nitrile hydratase, 3-cyanoalanine hydratase, cyanoalanine nitrilase, and indole-3-acetonitrile nitrilase activities. The gene is associated with cyanide and glucosinolate breakdown, auxin biosynthesis and transport, detoxification, and responses to sulfate starvation and misfolded proteins. It has been linked to IAA content, stem diameter, plant height, flowering time, herbicide sensitivity, disease tolerance, salt tolerance, and root and shoot development traits. Localisation evidence connects the product to the nucleus, cytosol, plasma membrane, apoplast, nucleolus, plasmodesma, and proteasome. Studies of related genes in other species link the family to nitrile hydrolysis, indole-3-acetonitrile sensitivity, pathogen resistance, and salt tolerance.
