| Comments | Abstract: "Low atmospheric CO2 in recent geological time led to the evolution of carbon-concentrating mechanisms (CCMs) such as C4 photosynthesis in >65 terrestrial plant lineages. [Investigators] know little about the impact of low CO2 on the Calvin-Benson cycle (CBC) in C3 species that did not evolve CCMs, representing >90% of terrestrial plant species." P.1844 right column 3rd paragraph: "Low CO2 will have exerted massive selective pressure on the CBC in species that did not evolve a CCM, representing ~90% of existing terrestrial plant species (primary sources)." |
