Summary

Self-Incompatibility is a means by which some plants prevent self-fertilization and promotes outcrossing. It has evolved independently in many different groups and plays a very important role in the ecology, evolution, and conservation of different species. In this episode, I sit down with Dr. Grace Burgin to explore the multitude of ways she is trying to understand self-incompatibility in the genus Phlox. Join us for a fascinating deep dive into what it takes to understand this phenomenon in Phlox.

0:00.0	Conversations like you're about to hear do not happen unless you support In Defensive Plants.
0:04.0	And now more than ever, we need conversations like this to reach as many ears as possible.
0:09.0	One of the best ways to help keep In Defensive Plants up and running is to become a patron over at patreon.com slash In Defensive Plants.
0:16.0	In return for a tiny bit of support each month, you will get access to a completely separate podcasts.
0:21.0	It explores a lot of really fun gardening topics, everything from seed collection and storage
0:25.2	to growing native plants, the struggles of trying to garden in different climates, and so much
0:30.2	more. It's a heck of a lot of fun. We're learning so much, and we're trying to share that with you.
0:34.5	So come on and join the Patreon over at patreon.com slash indefensive plants and help keep this show up and running in the process.
0:41.3	I hope to see you over there.
0:42.7	But in the meantime, on with the show.
0:45.5	Hello everyone and welcome to the Indefensive Plants podcast, the official podcast ofendifensiveplants.com.
0:50.6	What's up?
0:51.0	This is your host, Matt.
0:51.8	Welcome to the show.
0:52.6	How is everyone doing this week? I have a really
0:55.5	interesting topic for you today because it involves major mechanisms in the world of pollination
1:00.2	and evolution in plants. We are talking about the world of self- incompatibility in the genus flocks.
1:06.6	Now, self-incompatibility is pretty much what it sounds like. If pollen from that individual
1:10.9	or a genetically related individual falls on the stigma of that individual, there are mechanisms
1:16.5	for plants to reject that pollen. It helps increase outcrossing and genetic diversity, but we still
1:22.2	have so much to learn about it, and it's absolutely fascinating. Joining us to talk about this is Dr. Grace Bergen,
1:28.1	who takes a close look at self-incompatibility in flocks,
