Arabidopsis research roundup & interview

Description

Alistair McCormick (University of Edinburgh) provides an audio description of this paper in which he collaborates with UK colleagues in Norwich, Cambridge and Lancaster. This study aims to improve photosynthetic efficiency by introducing a component of the algal carbon concentrating mechanisms (CCMs) into the chloroplasts of higher plants. One mechanism for improving efficiency is brought about by the binding of rubisco (RBS) in a pyrenoid structure. In this study they replace an Arabidopsis RBS small subunit (SSU) with that from the algae Chlamydomonas reinhardtii and showed that a hybrid RBS complex formed with similar catalytic properties as that of the wildtpye complex. However the photosynthetic rate in these RBS complexes was reduced, demonstrating that the RBS SSU is key for determining the catalytic properties of the whole enzyme.
