Science on Sundays is a programme of free, informal, monthly science talks, bringing the latest discoveries in plant science, as well as research linked to the plant collection at CUBG, to our visitors in a 30 minute nutshell.
Delivery of carbon dioxide to photosynthesis inside plant leaves is a slow, diffusion-limited process in most plants. However, plants with C4 photosynthesis have the ability to increase carbon dioxide levels inside their leaves and thereby boost the efficiency of photosynthesis, somewhat like a turbo-charger in an internal combustion engine. Using phylogenetically controlled experiments, we are trying to find out in which ways the evolution of C4 photosynthesis has affected physiological responses which are qualitatively unaltered compared to the C3 ancestral state. In this talk I will focus specifically on the regulation of microscopic pores on the leaf surface called ‘stomata’, which control gaseous exchange, as well as the regulation of light harvesting in the chloroplast thylakoids, which is important to protect against high light damage.
Science on Sundays
A programme of free, informal, monthly science talks bringing the latest discoveries in plant science, as well as research linked to the plant collection at CUBG to our visitors in a 30 minute nutshell.
Normally, these talks take place in the Garden on the second Sunday of the month as a drop in session. However, as access to the Garden classroom is still restricted this year due to COVID-19, we will be running these talks as online webinars until such time as we can open the classroom to visitors again.
Please check the website and social media for updates.
Suitable for adults and children aged 12+
