Summary
Seeds are among the most important biological structures on this planet. Seeds have been instrumental in the diversification of plants, allowing them to spread into new habitats all over the globe. In fact, you and I would not be here if it were not for seeds. For these reasons and more, Dr. Cecilia Zumajo is fascinated by how seeds evolved. By looking at the genetic mechanisms that control seed development in various gymnosperms, Dr. Zumajo is opening new doors into our understanding of the development of these incredible structures. This episode was produced in part by Karma, Shelby, Christopher, Alvin, Arek, Chellie, Paul, Dani, Tara, Elly, Colleen, Natalie, Liam, Ario, Nathan, Laura, Cari, Laura, Kali, Margaret, Mary, Connor, Nathan, Jan, Jerome, Brian, Melody, Azomonas, Ellie, University Greens, Cynthia, John, Ashley, Peter, Cathrine, Melvin, OrangeJulian, Porter, Grif, Jules, Joan, Les, Marabeth, Ali, Margaret, Southside Plants, Robert, Keiko, Bryce, Brittany, Helen, Amanda, Mikey, Rhiannon, Michelle, Kate, German, Joerg, Alejandra, Cathy, Jordan, Judy, Steve, Kae, Carole, Mr. Keith Santner, Dana, Chloe, Aaron, Sara, Kenned, Vaibhav, Kendall, Christina, Brett, Jocelyn, Kathleen, Ethan, Kaylee, Runaway Goldfish, Ryan, Donica, Chris, Shamora, Alana, Laura, Alice, Sarah, Rachel, Joanna, Griff, Philip, Paul, Matthew, Clark, Bobby, Kate, Steven, Brittney, McMansion Hell, Joey, Catherine, Brandon, Hall, Vegreville Creek and Wetlands Fund, Kevin, Oliver, John, Johansson, Christina, Jared, Hannah, Katy Pye, Brandon, Gwen, Carly, Stephen, Botanical Tours, Moonwort Studios, Liba, Mohsin Kazmi Takes Pictures, doeg, Clifton, Stephanie, Benjamin, Eli, Rachael, Plant By Design, Philip, Brent, Ron, Tim, Homestead Brooklyn, Brodie, Kevin, Sophia, Mark, Rens, Bendix, Irene, Holly, Caitlin, Manuel, Jennifer, Sara, and Margie.

| 0:38.8 | What's up? This is your host, Matt. Welcome to the show. How's everyone doing this week? |
| 0:42.5 | Today we're talking about something extremely important in the plant world, the evolution and development |
| 0:47.4 | of fruits. Of course, many of us enjoy the taste of fruits every now and then or hopefully |
| 0:51.9 | incorporate them into at least portions of your diet, but the question becomes, how did they evolve? I think in many ways we take fruits |
| 0:59.4 | for granted as something that's always been, but that's not the case. And it's really interesting |
| 1:04.2 | to try to understand how that process got underway and how it's changed over time. Joining us to talk |
| 1:09.5 | about this is Dr. Cecilia Zumajo, who uses molecular techniques to try |
| 1:13.3 | to understand all of the processes involved in fruit development and evolution. |
| 1:18.0 | Now, a lot of her work focuses, of course, on angiosperms, specifically the model plant |
| 1:22.3 | Arabidopsis, which is a mustard, but it may surprise you how important gymnosperms |
| 1:27.2 | become in trying to understand |
| 1:28.5 | this process as well. By looking at different groups of gymnosperms, such as the ewes, the |
| 1:33.8 | ginkos, the needoms that produce fruit-like structures, Dr. Zamahou and her colleagues are trying |
