Acclimation, photosynthesis

Cyanobacteria, prokaryotic algae that perform oxygenic photosynthesis, respond to a decrease in ambient growth temperature by desaturating the fatty acids of membrane lipids to compensate for the decrease in the molecular motion of the membrane lipids at low temperatures. During low-temperature acclimation of cyanobacterial cells, the desaturation of fatty acids occurs without de novo synthesis of fatty acids [110, 111]. All known cyanobacterial desaturases are intrinsic membrane proteins that act on acyl-Hpid substrates.

Plants that are acclimated and adapted to dry conditions reduce their photosynthetic capacity and leaf nitrogen content toward a level that matches the low stomatal conductance that is necessary to conserve water in these environments (Wright et al., 2001). A high photosynthetic capacity provides little benefit if the plant must maintain a low stomatal conductance to conserve water. Conversely, low nitrogen availability or other factors that constrain leaf nitrogen concentration result in leaves with low stomatal conductance. This strong correlation between photosynthetic capacity and stomatal conductance maintains the balance between photosynthetic capacity and CO2 supply, i.e., the cohmitation of photosynthesis by dififusional and biochemical processes. In addition to their low photosynthetic capacity and low stomatal conductance, plants in... 

Despite the observed stimulative effects of CO2 on photosynthesis and plant growth, it is not clear that the effects will result in an increased storage of carbon in the world s ecosystems. One reason is that the measured effects of CO2 have generally been short term, while over longer intervals the effects are often reduced or absent. For example, plants often acclimate to higher concentrations of CO2 so that their rates of photosynthesis and growth return to the rates observed before the concentration was raised (Tissue and Oechel, 1987 Oren et al., 2001).
