Identification of Factors Governing Early Evolutionary Steps of C4 Photosynthesis in Moricandia   


C3-C4 intermediates, which display lower CO2 compensation points and Kranz-like anatomy, are considered as naturally occurring intermediates on the path of evolution from C3 to C4 photosynthesis. C3-C4 intermediates possess an efficient system for recycling of photorespiratory released CO2: the leaf mesophyll cells lack the P-protein of mitochondrial glycine decarboxylase (GDC), so for completion of the photorespiratory pathway, glycine is transported to the bundle sheath, where CO2 released from mitochondria can be efficiently recaptured by numerous, adjacent chloroplasts.

Within the project we would now like to better understand the importance of different biochemical and anatomical features for the functioning of this specific photorespiratory cycle as well as their manifestation in the genomes of the plants. In the genus Moricandia, species with C3 and C3-C4 intermediate photosynthesis co-exist in close phylogenetic proximity and provide ideal material to study early evolutionary steps of C4 photosynthesis.

The aim of the project is to gain insight into molecular background by dissecting key factors influencing CO2 efficiency of C3 plants and their possible involvement in early steps toward C4 photosynthesis.
