Acetohydroxyacid synthase (AHAS) catalyzes the first reaction in branch chain amino acids biosynthesis. This enzyme is the target of several herbicides, including all members of the imidazolinone family. Little is known about the expression of the three acetohydroxyacid synthase genes (ahas1, ahas2 and ahas3) in sunflower. The aim of this work was to evaluate ahas gene expression and AHAS activity in different tissues of sunflower plantlets. Three genotypes differing in imidazolinone resistance… CONTINUE READING
