Development of rice strains (oryza sativa L.) with resistance to acetyl coenzyme a carboxylase (acase) enzyme inhibitor herbicides obtained by gamma ray induced mutation

摘要

Abstract development of rice strains (oryza sativa L.) with resistance to acetyl coenzyme a carboxylase (acase) inhibitor herbicides obtained by gamma ray induced mutation. The present invention discloses the development of rice (oryza sativa L.) strains resistant to herbicides inhibiting the enzyme acetyl coenzyme a carboxylase (accase) by the application of gamma rays to the production of the oryza sativa species. Modified with the sequence described in seq. No: 1 and the rice strains comprise the substitution mutation of the guanine nitrogen base by thymine at the position corresponding to the codon giving amino acid 2027 at the carboxyl transferase site of the enzyme of the accase and the plants Of rice present a variation in the gene coding for the enzyme acetyl-coenzyme a carboxylase, Promoting resistance to inhibitory herbicides of the accase, compared to wild variety of the plant. 1/1
