Is it better/more advantageous to be a juvenile or an adult? As with humans, in plants, "it’s complicated"! In this episode of “A Botanical Podcast!” host Shiran Ben Zeev and Erica Lawrence-Paul discuss vegetative phase change in plants, i.e., the transition between juvenile and adult phases of vegetative growth. This transition can be visually subtle and easy to overlook in many species; however, morphological and physiological differences between juvenile and adult phases can lead to meaningful differences in plant and tissue function.

Dr. Erica Lawrence-Paul is an NSF postdoctoral fellow in Dr. Jesse Lasky’s lab in the Department of Biology at the Pennsylvania State University. She earned her doctorate at the University of Pennsylvania, studying the ecophysiological significance of the plant developmental transition, vegetative phase change, with a particular focus on photosynthetic and leaf carbon economic traits. Her current work focuses on understanding how natural variation in the timing of vegetative phase change and phase-specific differences in stress tolerance contribute to plant abiotic stress response and local adaptation.

In this episode, the host Shiran Ben Zeev and guest Jordan Dowell nerd out on a discussion of how plants choose to defend themselves against predators and/or manipulate other organisms to help them live their best lives, and how plants use chemistry to communicate---and what we can learn from that. They talk about the special challenges of surviving and thriving in harsh environments and touch on the evolution of chemical diversity and the effects of chemical diversity on organismal interactions across spatial and temporal scales.

Dr. Jordan Dowell is an assistant professor at Louisiana State University and an Associate Editor of the BSA's Applications in Plant Sciences. He studies the evolutionary ecology of plant-plant chemical communication and the impacts of multifunctional traits on biotic interactions from single-cells to landscapes using various techniques, from metabolomic and genomic approaches to remote sensing and field-based studies.

In this episode* of A Botanical Podcast, Dr. Andrea E. Berardi from James Madison University joins show host Dr. Shiran Ben Zeev to discuss the evolution of flower color and why plants change their colors. They discuss the role of plant-pollinator interactions and environmental relationships. This topic ties into the upcoming “Paradigm Shifts in Flower Color” special issue of the American Journal of Botany (https://botany.org/home/publications/ajb/ajb-special-issue-call-for-papers-paradigm-shifts-in-flower-color.html).
*Note: At 18:15, Dr. Berardi mentioned that nectar is an efficiency trait when in fact nectar is a reward trait. We thank her for pointing this out in post-production.

Andrea Berardi is an Assistant Professor at James Madison University in Harrisonburg, Virginia. She is a plant evolutionary biologist whose research focuses on evolutionary, genetic, and ecological processes underlying speciation, specifically focusing on how floral traits play a role in reproductive isolation and adaptation to the environment. Her favorite traits to study are floral color and plant secondary/specialized metabolites. She is co-editing a special issue of American Journal of Botany on "Paradigm Shifts in Flower Color," along with Justen Whittall, Eduardo Narbona, and José Carlos del Valle García.

BSA Publications Director Amy McPherson and host/producer Dr. Shiran Ben Zeev offer a preview of the first season of the BSA's new podcast: "A Botanical Podcast"! The podcast features conversations with botanists explaining their research and their passion for plants (and allied organisms). We’re focused on authors who choose to publish in Society journals, such as the American Journal of Botany, Applications in Plant Sciences, and Plant Science Bulletin---and we’ll include some surprises along the way!
