Photosynthetica, 2020 Climate changes severely influence photosynthetic activity of plants. Studies on the combined effect of drought and heat stress on photosynthesis, pigments, and xanthophyll cycle particularly in alfalfa (Medicago sativa L.) are limited.

Purification and characterization of phosphoenolpyruvate carboxylase from a cyanobacterium [PDF]
Journal of Bacteriology, 1986 Phosphoenolpyruvate (PEP) carboxylase (EC 4.1.1.31) was purified 100-fold from the cyanobacterium Coccochloris peniocystis with a yield of 10%. A single isozyme was found at all stages of purification, and activity of other beta-carboxylase enzymes was not detected. The apparent molecular weight of the native enzyme was 560,000.

Plant Physiology and Biochemistry, 2022 Three plant-type phosphoenolpyruvate carboxylase (PPC1 to PPC3) and two phosphoenolpyruvate carboxylase kinase (PPCKs: PPCK1 and 2) genes are present in the Arabidopsis thaliana genome. In seeds, all PPC genes were found to be expressed. Examination of individual ppc mutants showed little reduction of PEPC protein and global activity, with the notable ...

Plants, 2020 Sodic-alkalinity is a more seriously limiting factor in agricultural productivity than salinity. Oat (Avena nuda) is a salt-tolerant crop species and is therefore useful in studying the physiological responses of cereals to alkalinity.

Low irradiance alters carbon metabolism and delays flower stalk development in two orchids
Biologia Plantarum, 2013 In Phalaenopsis, lowering irradiance has been used to delay flower stalk development but the accompanying biochemical changes remain poorly understood. We cultured two commercial Phalaenopsis-type orchids, Phalaenopsis cv.

In Vitro Phosphorylation of Maize Leaf Phosphoenolpyruvate Carboxylase [PDF]
Plant Physiology, 1986 Autoradiography of total soluble maize (Zea mays) leaf proteins incubated with (32)P-labeled adenylates and separated by denaturing electrophoresis revealed that many polypeptides were phosphorylated in vitro by endogenous protein kinase(s). The most intense band was at 94 to 100 kilodaltons and was observed when using either [gamma-(32)P]ATP or [beta-(

Quantitative model for $^{13}$C tracing applied to citrate production and secretion of prostate epithelial tissue [PDF]
arXiv, 2019 Healthy human prostate epithelial cells have the unique ability to produce and secrete large amounts of citrate into the lumen of the prostate. Citrate is a Krebs cycle metabolite produced in the condensation reaction between acetyl-CoA and oxaloacetate in the mitochondria of the cell. With the application of $^{13}$C enriched substrates, such as $^{13}

Frontiers in Plant Science, 2019 Crassulacean acid metabolism (CAM) is a specialized mode of photosynthesis that exploits a temporal CO2 pump with nocturnal CO2 uptake and concentration to reduce photorespiration, improve water-use efficiency (WUE), and optimize the adaptability of ...
