Abstract: Plants interact with a huge diversity of microorganisms in associations ranging from parasitic to mutualistic, with either bacteria or filamentous fungi or oomycetes. Since plants colonized land 450 million years ago, these associations have evolved in opposite directions. Mutualism has been maintained for hundreds of million years whereas the interactions with parasites are fast evolving. Studying the interactions between plant lineages spanning 500 million years of diversification and multiple microorganisms, our goals are to discover the plant molecular mechanisms behind mutualistic and parasitic interactions with microorganisms and to understand how they evolved.

Note that the speaker will be joining us on Zoom. We will still meet in the auditorium to watch the talk together.
