摘要：
Two Descurainia Sophia populations, HB16 and HB08, were discovered in China and exhibit high resistance levels to tribenuron-methyl. Resistance ratio values of HB16 and HB08 were 153.47 and 651.20, respectively. The extractable acetohydroxy acid synthase (AHAS) activity was similar between resistant and susceptible populations. However, AHAS from HB16 and HB08 was less sensitive to inhibition of tribenuron-methyl comparing to susceptible Population. The tribenuron-methyl I-50 values for HB16 and HB08 were 46.25 and 54.07 greater than that for susceptible population respectively. Pro-197-Ser and Pro-197-Leu mutations were identified in AHAS extracted from HB16 and HB08 plants respectively. AHAS insensitivity of resistant D. Sophia caused by Pro197 mutation could be responsible for high resistance to tribenuron-methyl. (C) 2012 Elsevier Inc. All rights reserved.
