A gene, protein, carrier, recombinant genetically engineered bacterium and application thereof for accelerating fruit ripening

Abstract

The present invention relates to a gene for accelerating fruit ripening, said gene is: the coding region is a DNA molecule shown in SEQ ID NO.1; or: the coding region is 90% identical to the DNA molecule shown in SEQ ID NO.1 and above homologous DNA molecules. For the first time, the present invention excavates a gene (FRA gene) that promotes early fruit ripening outside the ethylene biosynthesis pathway, and constructs a carrier, realizing the innovative research and development of new germplasm of early-maturing fruit by using the gene transgenic method. Expression of FRA gene can accelerate fruit ripening.

Description

technical field [0001] The invention belongs to the field of agricultural biotechnology, in particular to a gene (FRA gene) for accelerating fruit ripening, a protein, a carrier, a recombinant genetically engineered bacterium and applications thereof. Background technique [0002] The phenomenon of fruit ripening is mainly controlled by a series of physiological and biochemical reactions triggered by ethylene. During the fruit ripening process, the respiration is strengthened, the starch is hydrolyzed into soluble sugars, and the organic acid is decomposed, which increases the sweetness of the fruit and reduces the sour taste; the hydrolysis of pectin makes the cell wall thinner, the fruit firmness decreases and softens, and the chlorophyll pigments degrade , Anthocyanins and carotenoid pigments are synthesized in large quantities, so that the color of the peel changes from green to red or yellow. EFE (ethylene forming enzyme) is a key enzyme in ethylene biosynthesis. The ...
