Title: Induction of seed germination in root parasitic plants by jasmonic acid
Research description: Strigolactone functions not only as a hormonal molecule that controls plant branching but also as a signal molecule that is secreted into the rhizosphere and induces symbiosis with mycorrhizal fungi. On the other hand, root parasitic plants, which cause extensive agricultural damage in Africa and other regions, have a unique germination system that recognizes strigolactone and germinates. This time, the research group discovered that jasmonates, which are other plant hormones, induce germination of root parasitic plants, and clarified the mechanism by which jasmonates induce germination. There is a possibility that jasmonic acid can be effectively used for the control of root parasitic plants, and there are high expectations for the further progress of this research.
