Mathesius Lab - Root microbe interactions - symbionts to parasites

Mathesius Lab

Legumes form a beneficial symbiosis with nitrogen fixing bacteria called rhizobia, that leads to the formation of root nodules. We are interested in the molecular mechanisms controlling nodule development in legumes. In particular, we are studying the relationship of nodule development with that of lateral roots and galls induced by parasitic nematodes. All three organogenesis programs involve a redirection of auxin transport and response. One of our aims is to identify the mechanism by which auxin transport is controlled in the different organogenesis programs. Our main focus is on the role of flavonoids in controlling auxin transport and responses, as well as on other functions of flavonoids in the communication between roots and soil microbes.

Highlights

Nodulation in Legumes

Legumes are a large family of flowering plants that are economically important due to their wide variety of uses in agriculture, most notably as a staple food source.
