| Description |
Most organisms inhabiting earth feed directly or indirectly on the products synthesized by the reaction of photosynthesis,
which at the current atmospheric CO2 levels operates only at two thirds of its peak efficiency. Restricting the
photorespiratory loss of carbon and thereby improving the efficiency of photosynthesis is seen by many as a good option
to enhance productivity of food crops. Research during last half a century has shown that several plant species developed
CO2-concentrating mechanism (CCM) to restrict photorespiration under lower concentration of available CO2. CCMs
are now known to be operative in several terrestrial and aquatic plants, ranging from most advanced higher plants to
algae, cyanobacteria and diatoms. Plants with C4 pathway of photosynthesis (where four-carbon compound is the first
product of photosynthesis) or crassulacean acid metabolism (CAM) may consistently operate CCM. Some plants
however can undergo a shift in photosynthetic metabolism only with change in environmental variables. More recently,
a shift in plant photosynthetic metabolism is reported at high altitude where improved efficiency of CO2 uptake is related
to the recapture of photorespiratory loss of carbon. Of the divergent CO2 assimilation strategies operative in different
oraganisms, the capacity to recapture photorespiratory CO2 could be an important approach to develop plants with
efficient photosynthetic capacity.
