英文摘要: Abstract(#br)Acetolactate synthase (ALS) inhibitor-resistant biotypes are the fastest growing class of herbicide-resistant weeds. Shepherd's purse ( Capsella bursa-pastoris (L.) Medik.), a tetraploid species and one of the most troublesome weeds in wheat production, has evolved ALS inhibitor resistance. To confirm and characterize the resistance of shepherd's purse populations to ALS-inhibiting herbicides, whole-plant bioassays were conducted. To investigate the molecular basis of resistance in shepherd's purse, the ALS gene was sequenced and compared between susceptible (S) and resistant (R) biotypes. Two partial intronless ALS genes (ALS-1 and ALS-2) were identified, and two heterozygous mutations (CCT to TCT in ALS-1 and CCT to CAT in ALS-2) at position 197 (Pro197Ser and Pro197His)...
