Tales of evolution from the mouths of plants
Dr Frances Sussmilch, Royal Society of Tasmania Peter Smith Medal winner will deliver this Peter Smith Lecture.

Most plant water loss (more than 90%) occurs through adjustable pores called stomata, typically found on leaves. Open stomata enable plants to acquire carbon dioxide for photosynthesis, but also allow water loss via evaporation from the plant into the atmosphere. Plants balance their need for CO2 for growth with the availability of water, opening and closing their stomatal pores in response to environmental signals. In flowering plants, stomatal movements are known to be controlled by complex genetic signalling pathways, with rapid stomatal closure in response to dehydration triggered by biosynthesis of the plant stress hormone abscisic acid (ABA). In this lecture, we will explore the genetic pathways that control stomatal closure and their evolution in land plants.

This lecture is free for members of the Royal Society of Tasmania.  Non-members are welcome to attend and donations are appreciated through our website rst.org.au. Suggested donation: $6; $4 for students and Friends of TMAG.
