Cucumber CsLsi2 gene, protein coded by same and application of cucumber CsLsi2 gene

Abstract

The invention relates to a cucumber CsLsi2 gene, a protein coded by the same and application of the cucumber CsLsi2 gene. The nucleotide sequence of the cucumber CsLsi2 gene is shown as SEQ ID NO: 1,and the sequence of the protein coded by the gene is shown as SEQ ID NO: 2. The cucumber CsLsi2 gene closely related to the cucumber bloom character is obtained by cloning after genome-wide association analysis and screening, the expression level of the gene is positively related to the cucumber bloom content, and early termination of amino acid translation is caused after the 754th basic group ofthe sequence, shown as SEQ ID NO: 1, of the cucumber gene is changed from C to T. Cloning and expression analysis of the cucumber CsLsi2 gene play a promoting role to a great extent in solving the problem that cucumber bloom gene resources are difficult to screen.

Description

technical field

[0001] The invention relates to the technical field of genetic engineering, in particular to the cucumber CsLsi2 gene and its encoded protein and application. Background technique

[0002] Cucumbers are an important source of dietary vitamin C. Because of its high yield and good benefits, it is an existing main vegetable crop, and the quality of cucumber directly determines the benefits of producers. Appearance quality belongs to the category of quality, and fruit cream is one of the important appearance qualities of cucumbers, which affects the sales of cucumbers to a large extent. Generally speaking, varieties with less fruit frost, bright and straight melon strips are more popular in the market. For a long time, there have been disputes about the composition and formation of cucumber fruit frost. One view is that the formation of cucumber fruit frost is the result of the vertical skin surface division of the single cell of the peel, and the hairy cells f...
