Abstract

The invention provides a strawberry NCED gene and a construction of a vector thereof. The nucleotide sequence of the gene is shown in SEQ ID NO:1 or has a cDNA sequence which has more than 90% of homology with the nucleotide sequence shown in SEQ ID NO:1 and is used to code the same functional protein. In the invention, the coding gene of the 9-cis-epoxy carotene dioxygenase is cloned from strawberry, the gene has critical regulating action on the synthesis of ABA in the processes of maturity and wilting or the conditions of drought, high temperature and low temperature. The invention lays the foundation for the research of the strawberry ABA anabolism mechanism and provides a gene source for the genetic engineering regulation of the metabolism and accumulation of ABA in plant.

Description

Technical field

[0001] The invention involves the field of genetic engineering, which specifically involves the construction of a strawberry NCED gene and the genetic plant expression carrier. Background technique

[0002] As a hormone that plays an important role in the entire life cycle of plants, it has extensive physiological effects in plant embryo development, seed dormant and germination, fruit maturity, and plants' response to adversity coercion.Growth and development plays an important role.The indirect synthesis of ABA needs to be a series of complex reaction changes such as aggregation, circularization, heterogeneity, oxidation, and cracking. Many of the details of the details are not clear. The research on its regulation mechanism has just started.How to express various genes, and the specificity of various enzymes needs to be further confirmed.9-cashmere carotenoids (NCED) catalyzed 9-catalyzed-cashmere-purple yellow and 9-new yellow quality cracking to form yellow a...
