Abstract

Tecticornia is a genus of succulent halophytic plants that are native to Australia. While most species carry out C3 photosynthesis, two species carry out C4 photosynthesis. This project aimed to investigate the steps in evolution of C4 photosynthesis in this genus and identify any potential C3-C4 intermediate species. Selected species from phylogenetic studies were analysed for C4-associated features at the anatomical, molecular and physiological levels. Tecticornia auriculata was identified as a potential C3-C4 intermediate species, and the steps in evolution of C4 photosynthesis in Tecticornia appear to deviate from the most widely accepted model of C4 evolution.
