Sulfadiazine foliar application comparison between wildtype and sul I transgenic Arabidopsis plants. (A) Col-0 plants grown in soil were either left untreated, or sprayed one to four times at three day intervals with a solution of 500 mg/L sulfadiazine and 0.03% L-77 silwet as indicated. Plant growth was photographed 21 days following the first sulfadiazine application. Partially stunted plants are marked with red arrows in the sample sprayed once. (B) The growth of three independent pCS4-BASK transgenic plant lines and the wildtype control plants (red box) 11 days after the first spraying with a 500 mg/L sulfadizine solution. (C) Plant growth observed at 21 days after the initial sulfadiazine application.
