Next SOL Seminar Online will be presented by Boris Igić on ​Self-incompatibility in Solanaceae and Beyond

Abstract.The majority of flowering plants are hermaphrodites. Nevertheless, many cannot self-fertilize, because they employ a system to recognize and reject their own pollen, termed self-incompatibility. The loss and gain of self-incompatibility is governed by a combination of ecological and genetic processes, including mate limitation and polyploidy. I will provide a broad overview and then use an array of empirical and theoretical data and methods to show that self-incompatibility (a suite of mechanisms for avoidance of self-fertilization) is frequently lost, despite being associated with long-term evolutionary success. Finally, I will discuss the general evolutionary implications, in light of ongoing work establishing the distribution of the RNase-based "Solanaceae mechanism" of self-incompatibility across core eudicots.

When? Friday 2nd October 4 pm (GMT+1)
