Physiological Responses of Common Bean Genotypes to Drought Stress
Drought compromises edible vegetable production worldwide, including common bean (Phaseolus vulgaris L.) an economically important crop that is highly dependent on optimum rainfall or abundant irrigation.

Measurement of Ribulose 1,5-Bisphosphate from Spinach Chloroplasts [PDF]
A technique has been developed for the rapid and simple measurement of ribulose 1,5-bisphosphate from isolated spinach chloroplasts. The endogenous ribulose bisphosphate was detected enzymically using (14)CO(2) and ribulose bisphosphate carboxylase/oxygenase released from the chloroplasts.

Background With increasing concerns over global warming and depletion of fossil-fuel reserves, it is attractive to develop innovative strategies to assimilate CO2, a greenhouse gas, into usable organic carbon. Cell-free systems can be designed to operate

Role of magnesium in carbon partitioning and alleviating photooxidative damage [PDF]
Magnesium (Mg) deficiency exerts a major influence on the partitioning of drymatter and carbohydrates between shoots and roots. One of the very early reactions of plants to Mg deficiency stress is themarked increase in the shootto- root dry weight ...

Photosynthesis and Ribulose 1,5-Bisphosphate Levels in Intact Chloroplasts [PDF]
The response of ribulose 1,5-bisphosphate levels and CO(2) fixation rates in isolated, intact spinach chloroplasts to pyrophosphate, triose phosphates, dl-glyceraldehyde, O(2), catalase, and irradiance during photosynthesis has been studied. Within 1 minute in the light, a rapid accumulation of ribulose bisphosphate was measured in most preparations of

The regulation of the air: a hypothesis [PDF]
We propose the hypothesis that natural selection, acting on the specificity or preference for CO<sub>2</sub> over O<sub>2</sub> of the enzyme rubisco (ribulose-1,5-bisphosphate carboxylase/oxygenase), has controlled the CO<sub ...

A novel expression cassette for the efficient visual selection of transformed tissues in florists' chrysanthemum (Chrysanthemum morifolium Ramat.). [PDF]
Constructs carrying visual reporter genes coupled with efficient promoters could facilitate the process of identification and selection of stable transformants in recalcitrant crops.

A precursor to the small subunit of ribulose-1,5-bisphosphate carboxylase [3-phospho-D-glycerate carboxylyase (dimerizing), EC 4.1.1.39] has been identified among the products of cell-free translation of polyadenylated RNA from spinach and pea.

Intermediates in the ribulose-1,5-bisphosphate carboxylase reaction.
At least two intermediates of the D-ribulose-1,5-bisphosphate carboxylase/oxygenase (EC 4.1.1.39) reaction were liberated in detectable amounts when the functioning enzyme from Rhodospirillum rubrum was quenched in acid. Using substrate labeled with 32P in C-1, [32P]orthophosphate (Pi) was found when the quenched solution was rapidly processed for ...
