A strawberry isocitrate lyase gene faicl6b and application thereof in regulating organic acid and soluble sugar metabolism

By cloning the strawberry isocitrate lyase gene FaICL6B and constructing a silencing vector, the problem of the influence of organic acid and soluble sugar content on the flavor of strawberry fruit was solved, and the citric acid and fructose content were increased, thus improving the fruit flavor. This method has the potential for molecular breeding applications.

Abstract

The application provides a strawberry isocitrate lyase gene FaICL6B and application thereof in regulating organic acid metabolism, and belongs to the technical field of plant genetic engineering, wherein the DNA sequence of the gene FaICL6B is shown as SEQ ID NO. 1, and the amino acid sequence of the expression protein of the gene FaICL6B is shown as SEQ ID NO. 2. The application obtains the FaICL6B gene through gene cloning and constructs a transient silencing vector by using a strawberry 'Hongyan' variety, determines the component and content changes of citric acid, malic acid, sucrose, fructose and glucose, and proves that the gene has important application value in regulating fruit sugar and acid quality of strawberry.
