Four atrazine-resistant mutants from the purple bacterium Rhodopseudomonas viridis were isolated. Sequence analysis revealed three different mutant strains carrying mutations in the herbicide-binding pocket: i) MAV 2: L212-Glu----Lys, ii) MAV 3: L216-Phe----Ser and iii) MAV 4 = MAV 5: L217-Arg----His, L220-Val----Leu. Except MAV 3 all Rps. viridis mutants are different from those selected by their resistance towards the closely related triazine terbutryn.
从绿色红假单胞菌中分离出了4株抗莠去津突变体。序列分析显示，有3种不同的突变菌株在除草剂结合口袋中发生了突变：i）MAV 2：L212 - 谷氨酸----赖氨酸，ii）MAV 3：L216 - 苯丙氨酸----丝氨酸，以及iii）MAV 4 = MAV 5：L217 - 精氨酸----组氨酸，L220 - 缬氨酸----亮氨酸。除MAV 3外，所有绿色红假单胞菌突变体均与通过对密切相关的三嗪类特丁津的抗性筛选出的突变体不同。
