Elucidation and genetic intervention of CO concentration mechanism in for increased plant primary productivity.

The rising global population is forcing the need for adapting alternative sustainable technologies for enhanced crop productivity. The CO Concentration Mechanisms (CCMs) evolved in algae to counter the inefficient CO fixing enzyme, RuBisCo and slower diffusion of CO in water offers good scope for the above purpose. The CCMs are single-celled CO supply mechanisms that depend on multiple CO/HCO transporters and acclimation states and accumulate 100-fold more CO than low CO environments.
