A method for creating a rice variety with low methane emission

Abstract

The invention provides a creation method of a low-methane-emission paddy rice variety, wherein the susiba-like gene sequence of the rice is represented as the SEQ ID No.1; the ATG initiation site andATG promoter domain position, which encode the susiba-like gene, are subjected to gene edition to obtain a rice mutant with frameshift mutation of the susiba-like gene; when the susiba-like gene is inactivated or is reduced in expression level, the metabolism causing transportation and accumulation of carbohydrates in the paddy rice is initiated, thus reducing the methane emission of a rice field.

Description

technical field [0001] The invention relates to the fields of gene editing technology and crop breeding, in particular to a method for creating rice varieties with low methane emission. Background technique [0002] The national conditions of my country's large population and small per capita arable land determine that ensuring my country's food security is the most important responsibility of agriculture. Rice hybrid breeding has made an important contribution to ensuring my country's grain production. However, with the progress of the times and increasingly complex environmental changes, it is difficult to efficiently meet the increasingly complex environmental changes and diversified market demands by pure yield breeding. The breeding focus of some rice breeders is also gradually focusing on the research and development of quality diversity and environment-friendly rice. [0003] The greenhouse effect has always been a global environmental issue with a high degree of co...
