The invention relates to the field of agricultural biotechnology, in particular to a glyphosate-resistant EPSPS mutant gene, a plant genetic transformation screening vector containing the gene and an application thereof. The goosegrass 5-enol-pyruvylshikimate-3-phosphate synthetase mutant gene provided by the invention can endow plants with high resistance to glyphosate. The plant genetic transformation screening vector and its screening method using the expression cassette as a screening marker provided by the present invention enable callus to use glyphosate as a screening agent in the tissue culture stage, and the obtained transgenic plants have high glyphosate herbicide resistance. The vector can be used as a transgenic screening vector with additional functional elements. During the transgenic process, the exogenous screening marker gene such as the plant source gene is used to replace the bacterial source, which not only enriches the plant transgenic screening method, but also effectively reduces the risk of transgenic plants Potential safety risks are beneficial to the commercial application of transgenic plants, and the market value and social benefits are good.

The invention relates to the field of agricultural biotechnology, in particular to a plant transgene screening vector pCALSm1 and its application. The plant genetic transformation screening vector provided by the present invention uses an expression cassette containing a rice acetolactate synthase mutant gene as a screening marker, and uses pyrimidine salicylates, imidazolinones and other herbicides as screening agents in the callus screening stage. The obtained transgenic plants have high resistance to herbicides such as pyrimidine salicylates and imidazolinones. The vector can be used as a transgenic screening vector with additional functional elements. During the transgenic process, plant endogenous genes are used without introducing exogenous screening marker genes such as bacterial sources. The potential safety risks of transgenic plants and public concerns about transgenic plants are conducive to the commercial application of transgenic plants, with good market value and social benefits.
