Abstract

The present invention provides one kind of soybean flowering time regulating gene GAL2 and its separating and cloning process and application. The soybean flowering time regulating gene GAL2 codes protein with the amino acid sequence as shown in SEQ ID No. 2 or the amino acid sequence of SEQ ID No. 2 through the substitution, deletion or addition of one or several amino acids and with the same function. Over expressing the gene can postpone the soybean flowering time to prolong the growth period of soybean extremely, best utilize the natural conditions and increase the yield. In addition, the present invention makes it easy to cultivating new soybean variety.

Description

technical field

[0001] The invention belongs to the technical field of genetic engineering, and in particular relates to a gene GAL2 regulating soybean flowering time and its application in plant breeding. Background technique

[0002] Soybean is one of the five major crops in my country, and it plays a very extensive role in the national economy: (1) It is an important source of human and animal plant protein; (2) It is one of the main sources of edible oil; (3) Soybean is a renewable Energy—one of the main raw materials for the production of biodiesel; (4) soybeans contain a large number of biologically active substances, such as isoflavones and D-chiro-inositol. However, for many years, my country's soybean supply has been 50% dependent on imports. Imported soybeans have obviously impacted our soybean production. Increasing soybean yield is the key to change this situation and realize soybean self-sufficiency.

[0003] Although my country is rich in soybean resources, s...
