The Brassica napus NCED family protein BnNCED3 shared high amino acid sequence identity with the AtNCED3 protein. The overexpression of BnNCED3 contributes to ABA accumulation, NO and ROS generation in transgenic Arabidopsis plants, thereby enhancing abiotic stress tolerance. Expression pattern assays revealed that BnNCED3 is highly expressed in senescencing leaves. BnNCED3 involvement in the control of the inhibition of seed germination, lateral root initiation, and early phase changes, and ABA bio-synthesis is required for the BnNCED3-mediated leaf senescence phenotype.
