Gene GmCIB1 and gene GmCRY2 of soybeans and blooming and senescence control functions of genes

Abstract

The invention discloses a gene GmCIB1 and a gene GmCRY2 of soybeans and blooming and senescence control applications of the genes. Specifically, the invention relates to the gene GmCIB1 and the gene GmCRY2 of soybeans, DNA molecules containing the genes, vectors, gene encoded protein and relevant transformed cells and transgenic plants, and further relates to applications of the genes in control of plant leaf senescence and blooming as well as a method for cultivating relevant transgenic plants, and the gene GmCIB1 and the gene GmCRY2 are represented as SEQ ID NO: 1 or 3.

Description

technical field The invention relates to the field of biotechnology, in particular to soybean GmCIB1 gene and GmCRY2 gene and application thereof. Background technique In nature, the study of plant senescence has become one of the important issues in plant life science research. Thimann et al. proposed in 1978 that plant senescence is a series of decline processes during growth and development (Thimann, 1978). More than ten years later, Roach proposed that senescence is a physiological process in which the survival and reproductive ability of plants gradually decrease with the growth of age (Roach et al., 1993). In 1997, Nooden perfected this concept, proposing that senescence is an ordered degradation process of plant somatic cell death (Nooden et al., 1997). Like other senescence events in plants, leaf senescence is the final stage of development, culminating in leaf death, thus limiting leaf life cycle and lifespan. Elucidation of the regulatory process of leaf senesc...
