    <div>I have not found anything in correlation with low photosynthesis, but there is non-photosynthetic Carbon-Dioxide fixation in roots – especially known in legumes as to produce the carbon skeletons for nitrogen fixation. I had never heard about this before I started researching for the carbon course. Also Carbon dioxide can invade the root being transported as solute in the xylem and be subsequently fixed in the stem by non-foliar photosynthesis in some tissues of the stem (which is intended for refixation of respired CO2 as the CO2 escape in stems is not as available as in leaves, which leads to much higher CO2 concentrations). What I could not find is the efficiency or percentages or other factors. These pathways are no weird magic, they are established and researched, but they are just not common knowledge at all.
