specific Embodiment approach 1

[0013] Specific embodiment 1: The soybean growth period gene J gene sequence of this embodiment is shown in the sequence table Seq ID No: 1.

[0014] In this embodiment, the F2 population produced by crossing Harosory and BR121 is studied, and the J gene is determined, which is closely related to the growth period of soybean.

[0015] In this embodiment, the J gene is expressed in soybeans by means of soybean genetic transformation, and it is verified that the J gene of the present invention can significantly prolong the maturity period of soybeans.

specific Embodiment approach 2

[0016] Embodiment 2: The amino acid sequence of the protein encoded by the soybean growth period gene J in this embodiment is shown in Seq ID No: 2 in the sequence table.

[0017] Verify effect of the present invention by following test:

Abstract

The invention relates to a soybean growth period gene J and an encoding protein thereof, and aims to provide the soybean growth period gene J and the encoding protein thereof. The gene sequence of the soybean growth period gene J provided by the invention is shown as a sequence table Seq ID No:1. The amino acid sequence of the encoding protein of the soybean growth period gene J provided by the invention is shown as a sequence table Seq ID No:2. According to the soybean growth period gene J and the encoding protein thereof, soybean genetic transformation verifies that the gene J inhabits the physiological function in the growth period of soybean. The soybean growth period gene J and the encoding protein thereof are applied to the field of soybean gene engineering.

Description

technical field [0001] The present invention relates to soybean growth period gene J and its encoded protein. Background technique [0002] Soybeans provide human beings with important vegetable proteins and oils. Worldwide, soybeans are cultivated in a wide range of regions ranging from high latitudes in northern Europe, Sweden and North America to Canada, and south to Brazil and Argentina. However, the latitude span suitable for planting a single variety or germplasm resource is generally small. The long puberty trait, that is, the prolongation of the growth period under short-day conditions, plays an important role in extending the adaptation range of soybean varieties to low latitudes, and provides a theoretical basis for the cultivation and management of soybeans in tropical countries. [0003] Kiihl found in an experiment in 1979 that three recessive genes determine the late flowering traits of soybean under short-day conditions. In Brazil, the long pubertal trait ha...
