23 Jul Coding sequence and application of epoxy carotene dioxygenase OsNCED3 gene of rice
Abstract
The invention belongs to the technical field of genetic engineering and particularly relates to a coding sequence and an application of an epoxy carotene dioxygenase OsNCED3 gene of rice. A method specifically comprises steps as follows: a nucleotide coding sequence of the OsNCED3 gene is cloned, isogeny comparison of the sequence is performed, space expression modes of different endogenous organsand tissue of the gene of the rice and expression mode change after drought, salt stress and plant hormone treatment are analyzed and identified, a Tilling mutant is obtained on the basis of rice Zhonghua11, molecular identification and stress experiments are performed, gene expression change and resistance change are detected. The OsNCED3 gene can be used for plant variety improvement includingimprovement of rice senescence resistance and improvement of the capability of rice for coping with the dark condition, so that the rice yield is improved.
