WebPhosphoenolpyruvate carboxylase (PEPC) has a variety of functions in plants, including a major anaplerotic role in replenishing the tricarboxylic acid cycle with intermediates to meet the demand of carbon skeletons for synthesis of organic acids and amino acids. Various transgenic C 3 plants that overproduce PEPC have been produced and analyzed in detail.

C4 carbon fixation or the Hatch–Slack pathway is one of three known photosynthetic processes of carbon fixation in plants. It owes the names to the 1960's discovery by Marshall Davidson Hatch and Charles Roger Slack that some plants, when supplied with CO2, incorporate the C label into four-carbon molecules first. … See more The first experiments indicating that some plants do not use C3 carbon fixation but instead produce malate and aspartate in the first step of carbon fixation were done in the 1950s and early 1960s by Hugo Peter Kortschak and … See more In C3 plants, the first step in the light-independent reactions of photosynthesis is the fixation of CO2 by the enzyme RuBisCO to form 3-phosphoglycerate. However, RuBisCo … See more Different formulations of efficiency are possible depending on which outputs and inputs are considered. For instance, average quantum … See more About 8,100 plant species use C4 carbon fixation, which represents about 3% of all terrestrial species of plants. All these 8,100 species are See more C4 plants often possess a characteristic leaf anatomy called kranz anatomy, from the German word for wreath. Their vascular bundles are surrounded by two rings of cells; the inner ring, … See more To meet the NADPH and ATP demands in the mesophyll and bundle sheath, light needs to be harvested and shared between two distinct electron transfer chains. ATP may be produced in the bundle sheath mainly through cyclic electron flow … See more C4 plants have a competitive advantage over plants possessing the more common C3 carbon fixation pathway under conditions of drought, high temperatures, and See more Web2 days ago · Gene mapping was completed for CAM and C4 cycle pathways and could not find a mapping for three genes in the C3 cycle pathway. Those three genes ... It indicates that the Peepal tree adapts to the CAM pathway and can fix nocturnal carbon dioxide using the PEP carboxylase (PEPC) enzyme and accumulate malate by the enzyme malate ... WebGene expression, protein accumulation and enzyme activity were confirmed for all five transgenes, and intercellular localization of proteins was analysed. 13CO2 labelling … farmall factory
