Major physiological traits affected by elevated CO₂ and elevated temperature.

Biochemical and phenotypic changes in legumes when exposed to elevated CO₂ alone (left) and along with increased temperatures (right). The major phenotypic and biochemical parameters are described in detail in the review section 1. The bottom part of the figure shows the sequential changes in rhizopsphere when exposed to elevated CO₂ causing increased C which affects Biological Nitrogen Fixation (BNF) with consequences on nodulation in roots.
