One widely accepted scenario of C4 evolution predicts a preconditioning in C3 ancestral lineages such that certain physiological and anatomical traits are favorable for the development of the C4 trait. In the context of CEPLAS we aim to study relevant anatomical leaf traits. Towards this end we plan to use genome wide association mapping and forward genetic approaches in collaboration with Koornneef, Schurr, Höcker and Westhoff labs.
