Epsps enzyme mutant, nucleic acid molecule, expression cassette, expression vector, recombinant bacterium or recombinant cell and use thereof

Abstract

Provided are an EPSPS enzyme mutant, a nucleic acid molecule, an expression cassette, an expression vector, a recombinant bacterium or a recombinant cell and use thereof. The EPSPS enzyme mutant can effectively solve the problem of non-selectable damage to crops caused by herbicides such as glyphosate, and provides a new route for cultivating glyphosate-resistant crop varieties. Moreover, the EPSPS enzyme mutant also has relatively high practicability and promotional value, can improve a weed control effect, reduce weeding costs, and elevate crop yields in agricultural production. Besides, it further provides an expression cassette expressing the EPSPS enzyme mutant, where the expression cassette contains an EPSPS mutant gene conferring glyphosate resistance on a variety of plants such as soybean and rice.
