Photorespiration is the process that recycles 2-phosphoglycolate back to 3-phosphoglycerate resulting from the oxygenase activity of Rubisco. Recent studies proved the importance of photorespiration for plant survival under stress conditions, including drought stress. In the present study, physiol., biochem. and mol. responses of a moderately drought-tolerant plant Lotus corniculatus to PEG-mediated drought stress were examined Growth, stomatal conductance (gs), maximum quantum yield of photosystem II (Fv/Fm), CO2 assimilation (A), electron transport (ETR) and transpiration rates (E) were decreased, while intercellular CO2 concentrations (Ci), non-photochem. quenching (NPQ) and photorespiration rates were increased in the drought stress-exposed plants. Activities and expression profiles of photorespiratory cycle enzymes correlated well with the increased photorespiration rates. In the line of our results, we conclude that the activation of photorespiration for recycling 2-phosphoglycolate (2PG) to chloroplast facilitated the maintenance of growth and drought stress tolerance in L. corniculatus. Accordingly, we can speculate that drought stress exerted by PEG20 (20% PEG6000) with an osmotic pressure of -0.73 MPa may be a threshold level for drought tolerance in L. corniculatus since the long-term effects of PEG20 on tolerance-related parameters (RGR, membrane integrity, leaf water status and photosynthesis) were more remarkable. This study involved multiple reactions and reactants, such as (4-Formyl-5-hydroxy-6-methylpyridin-3-yl)methyl dihydrogen phosphate (cas: 54-47-7SDS of cas: 54-47-7).
(4-Formyl-5-hydroxy-6-methylpyridin-3-yl)methyl dihydrogen phosphate (cas: 54-47-7) belongs to pyridine derivatives. Pyridine has a conjugated system of six π electrons that are delocalized over the ring. The molecule is planar and, thus, follows the Hückel criteria for aromatic systems. Many analogues of pyridine are known where N is replaced by other heteroatoms . Substitution of one C–H in pyridine with a second N gives rise to the diazine heterocycles (C4H4N2), with the names pyridazine, pyrimidine, and pyrazine.SDS of cas: 54-47-7
