Title:
GLUTAMINE SYNTHETASE MUTANT AND APPLICATION THEREOF IN BREEDING OF GLUFOSINATE-AMMONIUM-RESISTANT PLANT VARIETIES
Document Type and Number:
WIPO Patent Application WO/2023/040564
Kind Code:
A1
Abstract:
Provided are a glutamine synthetase mutant and an application thereof in breeding of glufosinate-ammonium-resistant plant varieties. The glutamine synthetase mutant is obtained by mutation at position n of a wild-type glutamine synthetase, the position is A, G, M, N, Q, S, T, V or deleted after the mutation, and the position corresponds to position 69 of an amino acid sequence as represented by SEQ ID NO. 1.
