Rubisco activities, properties, and regulation in three different C4 grasses under drought
In C4 plants, water deficit may decrease photosynthetic CO2 assimilation independently of changes in stomatal conductance, suggesting decreased turnover by ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco). The activity and biochemistry of Rubisco was studied in three different C4 grasses: Paspalum dilatatum, Cynodon dactylon, and Zoysia japonica. The objectives were to characterize the...
متن کاملEffects of phosphorylation on phosphoenolpyruvate carboxykinase from the C4 plant Guinea grass.
In the C4 plant Guinea grass (Panicum maximum), phosphoenolpyruvate carboxykinase (PEPCK) is phosphorylated in darkened leaves and dephosphorylated in illuminated leaves. To determine whether the properties of phosphorylated and non-phosphorylated PEPCK were different, PEPCK was purified to homogeneity from both illuminated and darkened leaves. The final step of the purification procedure, gel ...
متن کاملClimate and the U.S. distribution of C4 grass subfamilies and decarboxylation variants of C4 photosynthesis.
I compared the C(4) grass flora and climatic records for 32 sites in the United States. Consistent with previous studies, I found that the proportion of the grass flora that uses the NADP malic enzyme (NADP-ME) variant of C(4) photosynthesis greatly increases with increasing annual precipitation, while the proportion using the NAD malic enzyme (NAD-ME) variant (and also the less common phosphoe...
متن کاملDigestibility and nitrogen retention in llamas and goats fed alfalfa, C3 grass, and C4 grass hays
The objective of this experiment was to determine the relative digestive capabilities and N retention between goats and llamas fed three forages. Four llamas (2 yrs; 125± 7.3 kg BW) and four Boer-cross goats (2 yrs; 53± 8.4 kg BW) were housed in metabolism crates and fed alfalfa (Medicago sativa; ALF), temperate C3 grass (Festuca arundinacea; C3G) and tropical C4 grass (Cynodon dactylon; C4G) h...
متن کاملReductions of Rubisco activase by antisense RNA in the C4 plant Flaveria bidentis reduces Rubisco carbamylation and leaf photosynthesis.
To function, the catalytic sites of Rubisco (EC 4.1.1.39) need to be activated by the reversible carbamylation of a lysine residue within the sites followed by rapid binding of magnesium. The activation of Rubisco in vivo requires the presence of the regulatory protein Rubisco activase. This enzyme is thought to aid the release of sugar phosphate inhibitors from Rubisco's catalytic sites, there...
