Building a pyrenoid-based CO2-concentrating mechanism into plants

Tuesday 4 October 2022, 1.00PM

Speaker(s): Dr Alistair McCormick, University of Edinburgh

Many photosynthetic species have evolved CO2-concentrating mechanisms (CCMs) to improve the efficiency of CO2 assimilation by Rubisco and reduce the negative impacts of photorespiration. As the majority of plants (i.e. C3 plants) lack an active CCM, introducing a functional heterologous CCM into crops is a key engineering ambition to enhance yield potential. Through advances in our understanding of the Chlamydomonas CCM, the complex task of building a functional pyrenoid-based CCM has moved several steps closer to reality, particularly now with a model-based roadmap to guide future engineering efforts. Here I will discuss recent progress in transferring key components and features of the Chlamydomonas CCM into higher plants.
