Rubisco and Rubisco Activase Play an Important Role in the Biochemical Limitations of Photosynthesis in Rice, Wheat, and Maize under High Temperature and Water Deficit. [PDF]
To understand the effect of heat and drought on three major cereal crops, the physiological and biochemical (i.e., metabolic) factors affecting photosynthesis were examined in rice, wheat, and maize plants grown under long-term water deficit (WD), high ...

Genetic determinants controlling maize rubisco activase gene expression and a comparison with rice counterparts [PDF]
Background Rubisco activase (RCA) regulates the activity of Rubisco and is a key enzyme of photosynthesis. RCA expression was widely reported to affect plant photosynthesis and crop yield, but the molecular basis of natural variation in RCA expression in

Changes in PEP Carboxylase, Rubisco and Rubisco activase mRNA levels from maize (Zea mays) exposed to a chronic ozone stress [PDF]
We quantified the ozone impact on levels of Zea mays L. cv. Chambord mRNAs encoding C4-phosphoenolpyruvate carboxylase (C4-PEPc), ribulose-l,5-bisphosphate carboxylase/oxygenase small and large subunits (Rubisco-SSU and Rubisco-LSU, respectively) and ...

A Conserved Sequence from Heat-Adapted Species Improves Rubisco Activase Thermostability in Wheat
Eleven amino acids conserved in Rubisco activase (Rca) variants present in warm-adapted species increase the thermostability of wheat Rca by 7°C. The central enzyme of photosynthesis, Rubisco, is regulated by Rubisco activase (Rca).

Identification of putative RuBisCo activase (TaRca1) ˗ the catalytic chaperone regulating carbon assimilatory pathway in wheat (Triticum aestivum) under the heat stress [PDF]
RuBisCo activase (Rca) is a catalytic chaperone involved in modulating the activity of RuBisCo (key enzyme of photosynthetic pathway). Here, we identified eight novel transcripts from wheat through data mining predicted to be Rca and cloned a transcript ...

Improving Crop Yield through Increasing Carbon Gain and Reducing Carbon Loss [PDF]
Photosynthesis is a process where solar energy is utilized to convert atmospheric CO2 into carbohydrates, which forms the basis for plant productivity. The increasing demand for food has created a global urge to enhance yield. Earlier, the plant breeding

Two Residues of Rubisco Activase Involved in Recognition of the Rubisco Substrate [PDF]
Rubisco activase is an AAA(+) protein, a superfamily with members that use a "Sensor 2" domain for substrate recognition. To determine whether the analogous domain of activase is involved in recognition of ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco, EC 4.1.1.39), two chimeric activases were constructed, interchanging a Sensor 2-containing

Rubisco Activases: AAA+ Chaperones Adapted to Enzyme Repair [PDF]
Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco), the key enzyme of the Calvin-Benson-Bassham cycle of photosynthesis, requires conformational repair by Rubisco activase for efficient function. Rubisco mediates the fixation of atmospheric CO2 by catalyzing the carboxylation of the five-carbon sugar ribulose-1,5-bisphosphate (RuBP).

Non-Foliar Photosynthesis in Pea (Pisum sativum L.) Plants: Beyond the Leaves to Inside the Seeds [PDF]
In addition to leaves, photosynthesis can occur in other green plant organs, including developing seeds of many crops. While the majority of studies examining photosynthesis are concentrated on the leaf level, the role of other green tissues in the ...
