Outline of Final Research Achievements

Parasitic weeds damage agriculture in arid and semi-arid land worldwide and jeopardize global food security. We had conducted metabolome analysis of parasitic weed germination and revealed that planteose metabolic pathway can be promising target for their selective control. In this study, we tried to elucidate enzymes involved in planteose metabolic pathway. Tomato mutants lacking genes involved in planteose biosynthesis were obtained for gene identification. An enzyme catalyzing the first hydrolysis of planteose was successfully elucidated.
