Resistance to glufosinate is proportional to phosphinothricin acetyltransferase expression and activity in LibertyLink (R) and WideStrike (R) cotton

摘要

Insertion of the gene encoding phosphinothricin acetyltransferase (PAT) has resulted in cotton plants resistant to the herbicide glufosinate. However, the lower expression and commensurate reduction in PAT activity is a key factor in the low level of injury observed in the WideStrike (A (R)) cotton and relatively high level of resistance observed in LibertyLink (A (R)) cotton.
