The engineering process of C₄ photosynthesis into C₃ plants requires an increased activity of phosphoenolpyruvate carboxylase (PEPC) in the cytosol of leaf mesophyll cells. The literature varies on the physiological effect of transgenic maize (Zea mays) PEPC (ZmPEPC) leaf

Herbicides inhibiting acetyl-coenzyme A carboxylase (ACCase) are very effective in controlling grass weeds including weedy-rice in paddy rice production systems. The ACCase inhibitor affects the enzyme by blocking fatty acid biosynthesis resulting in plant death. The herbicide resistance in rice is

Ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) activase catalyzes the activation of RuBisCO in vivo. Two full length cDNAs designated as OsrcaA1 and OsrcaA2 encoding two RuBisCO activase isoforms of 47 and 43 kDa, respectively, have been cloned and characterized. The two isoforms were 99%

Employing high-resolution two-dimensional electrophoresis (2-DE), we studied changes in the rice leaf protein patterns, in response to applied heavy and alkaline metals, important environmental pollutants in our surroundings. Drastic changes in 2-DE protein patterns after treatment with copper,

Suppression subtractive hybridization was carried out to enrich gene fragments over-expressed in rice leaves by subtraction to rice roots, from which two identical cDNA fragments were identified to encode putative phosphoenolpyruvate carboxylase. Then the corresponding full-length cDNA (Osppc) is

Changes in photosynthesis and the ribulose 1,5-bisphosphate (RuBP) carboxylase level were examined in the 12th leaf blades of rice (Oryza sativa L.) grown under different N levels. Photosynthesis was determined using an open infrared gas analysis system. The level of RuBP carboxylase was measured by

Phosphoenolpyruvate carboxylase (PEPC) is a key enzyme of primary metabolism in bacteria, algae and vascular plants, and it undergoes allosteric regulation by various metabolic effectors. Rice (Oryza sativa) has five plant-type PEPCs, four cytosolic and one chloroplastic. We investigated their

Effects of growth temperature on the photosynthetic gas-exchange rates and their underlying biochemical properties were examined in young, fully expanded leaves of rice (Oryza sativa L.). The plants were grown hydroponically under day/night temperature regimes of 18/15[deg]C, 23/18[deg]C, and

To understand the link between long-term drought tolerance and short-term drought responses in plants, transgenic rice (Oryza sativa L.) plants over-expressing the maize C4-pepc gene encoding phosphoenolpyruvate carboxylase (PC) and wild-type (WT) rice plants were subjected to PEG 6000 treatments to

The enzymic properties of ribulose 1,5-bisphosphate (RuBP) carboxylase/oxygenase purified from rice (Oryza sativa L.) leaves were studied. Rice RuBPcarboxylase, activated by preincubation with CO(2) and Mg(2+) like other higher plant carboxylases, had an activation equilibrium constant (K(c)K(Mg))

It has been suggested that caffeine acts as an allelochemical which influences the germination and growth of plants. The effect of caffeine on the expression profiles of proteins was investigated in shoot-root axes of rice (Oryza sativa) seedlings. Two-dimensional difference gel electrophoresis

The coleoptile of rice (Oryza sativa L. cv. Nippon-bare) emerges from an imbibed seed on day 2 after sowing. Then, it matures and senesces rapidly. For analysis of the senescence pattern within individual coleoptiles, we monitored the distribution of chlorophyll (Chl) in entire coleoptiles and in

The amounts of ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco), total chlorophyll (Chl), and total leaf nitrogen were measured in fully expanded, young leaves of wheat (Triticum aestivum L.), rice (Oryza sativa L.), spinach (Spinacia oleracea L.), bean (Phaseolus vulgaris L.), and pea

The accumulation of soluble carbohydrates resulting from growth under elevated CO2 may potentially signal the repression of gene activity for the small subunit of ribulose-1,5-bisphosphate carboxylase/oxygenase (rbcS). To test this hypothesis we grew rice (Oryza sativa L.) under ambient (350 &mgr;L
