Aquatic carbon concentrating mechanisms as a source of genes for improving terrestrial C3 photosynthesis

All photosynthesis is ultimately contingent on the efficacy with which CO2 is supplied to the active sites of Rubisco. Extant photosynthetic organisms have adapted to the relatively low atmospheric and aquatic CO2 :O2 ratios, either by adopting Rubisco variants with high specificity for CO2 or by acquiring some form of CO2 -pump to turbocharge photosynthesis.

Making use of components of the carbon concentrating mechanism (CCM) present in the green alga Chlamydomonas for transfer to land plant chloroplasts is the focus of a collaborative effort between the Griffiths lab, JIC (Prof. Alison Smith) and Carnegie/Stanford (Dr. Martin Jonikas) – Combining Algal and Plant Photosynthesis (BBSRC BB/I024518/1).

Here, we present the latest collective progress in identifying key CCM components, understanding the regulation of the algal CCM and pyrenoid biogenesis, and introducing algal genes into the model system Arabidopsis.
