Abstract

Photosystem II herbicides inhibit electron transfer from QA to QB by binding to the D1 protein thus causing a displacement of the plastoquinone QB [1,2]. Competition between the herbicides and QB for the same binding site has been demonstrated [2,3]. Different amino acid substitutions in the D1 protein have been previously found to reduce herbicide binding thereby conferring herbicide-resistance [4,5].
