OLD3 — Brassica napus

Summary

BnOLD3 (DARMORV10_A08P11530.1) on chromosome A08 of oilseed rape encodes a cysteine synthase family protein with multiple enzymatic activities, including cysteine synthase, L-serine O-acetyltransferase, beta-pyrazolylalanine synthase, and L-3-cyanoalanine synthase activities. The gene is associated with cysteine anabolism, ethylene anabolism, sulphate transport, fruit ripening, pollen tube growth, and negative regulation of leaf senescence. It has been linked to traits including sulfur sensitivity, nitrate uptake, seedling growth and development trait, root thickness, seed growth and development trait, and plant growth and development trait. Associations with cadmium tolerance, salt stress tolerance, heavy metal stress tolerance, and leaf senescence have been observed. The gene product localizes to the cytosol, chloroplast stroma, mitochondria, apoplast, plant-type vacuole, Golgi complex, and plasmalemma.
