High Antioxidant Ability Confer Resistance to Atrazine in Commelina communis L.

ABSTRACT: Asiatic dayflower (Commelina communis L.) is a detrimental weed that mainly infests corn and soybean fields in China. Recently, some C. communis populations have exhibited resistance to atrazine, intensifying the difficulties in controlling the weed. However, little is known on the mechanism underlying C. communis resistance to atrazine. Therefore, two populations collected from Jilin (JL-1) and Jiangsu (JS-10) provinces of China were used to evaluate their growth responses to atrazine. The results showed that the JL-1 population displayed a low level of resistance to atrazine compared with JS-10 population, with the resistant index (RI) value of 2.9. To determine if a mutation in the psbA gene was the basis for varied resistance to this herbicide, the full-leng
