Water deficit in field-grown Gossypium hirsutum primarily limits net photosynthesis by decreasing stomatal conductance, increasing photorespiration
, and increasing the ratio of dark respiration to gross photosynthesis.
C4 plants possess biochemical and anatomical mechanisms to raise the intercellular carbon dioxide concentration at the site of fixation; this reduces (and sometimes eliminates) carbon losses by photorespiration
Leaf orientation, photorespiration
and xanthophyll cycle protect young soybean leaves against high irradiance in field.
O2] can be attributed to the PSII heterogeneity (Melis, 1991), the increase of photorespiration
(Raven & Johnston, 1991) and the underexplored phenomena of PSII cycling (Feikema et al.
Penuelas J, Llusia J (2002) Linking photorespiration
, monoterpenes and thermotolerance in Quercus.
To construct accurate model predictions for soybean crops, some specific aspects, such as photorespiration
and the CO2 assimilation rate, must be taken into consideration.
Libert and Franceschi (1987) suggested that photorespiration
is not a prerequisite for oxalate synthesis.
2] increases rate of fixed carbon and also suppresses photorespiration
The change in succinate dehydrogenase activity in different species may be because of the fact that change in the enzyme significantly affects the rate of TCA functioning and also the balance between photosynthesis, respiration and photorespiration
in the cell (Popov et al, 2007).
3] species have a version of respiration called photorespiration
that can use up a significant portion of the carbon energy fixed during photosynthesis.
In C3 plants, respiration rates increase in the light, a process termed photorespiration
, and this increased use of photosynthesis decreases the efficiency of carbon fixation.
2]) is produced by the glycollate oxidase reaction in the process of photorespiration
(Foyer et al.
