Core promoter acetylation is not required for high transcription from the phosphoenolpyruvate carboxylase promoter in maize [PDF]
, 2009 Background Acetylation of promoter nucleosomes is tightly correlated and mechanistically linked to gene activity. However, transcription is not necessary for promoter acetylation.

Comparative proteomics analysis of root and nodule mitochondria of soybean
Plant, Cell &Environment, EarlyView.Abstract Legumes perform symbiotic nitrogen fixation through rhizobial bacteroids housed in specialised root nodules. The biochemical process is energy‐intensive and consumes a huge carbon source to generate sufficient reducing power. To maintain the symbiosis, malate is supplied by legume nodules to bacteroids as their major carbon and energy source ...

In vivo monoubiquitination of anaplerotic phosphoenolpyruvate carboxylase occurs at Lys624 in germinating sorghum seeds [PDF]
, 2014 Phosphoenolpyruvate carboxylase (PEPC; EC 4.1.1.31) is an important cytosolic regulatory enzyme that plays a pivotal role in numerous physiological processes in plants, including seed development and germination.

, 2010 This work describes the discovery of novel phosphoenolpyruvate carboxylase (PEPC) genes and theiractive catalitic polypeptides in the green microalga Chlamydomonas reinhardhii. Green-algal PEPC hasbeen unexplored before in molecular terms. Our recent studies have reported the molecular cloning ofthe two PEPC genes, Ppc genes in Creinhardtii (CrPpcl ...

Interrelationship between type three secretion system and metabolism in pathogenic bacteria [PDF]
, 2014 Before the advent of molecular biology methods, studies of pathogens were dominated by analyses of their metabolism. Development of molecular biology techniques then enabled the identification and functional characterisation of the fascinating toolbox of

Journal of Quaternary Science, Volume 40, Issue 4, Page 645-656, May 2025.ABSTRACT The charring process can preserve archaeobotanical remains, providing valuable insights into past climates, agricultural practices, and plant growth conditions. However, the impact of charring on stable isotopes, especially at temperatures above 300°C, remains poorly understood.

Physiological and biochemical analysis of transgenic rice over-expressing C4 genes from maize and the diversity and plasticity of C4 photosynthesis in Eleocharis (Cyperaceae) [PDF]
, 2007 From a photosynthetic point of view, yield of some crops may be furtherimproved by increasing the photosynthetic capacity of the source leaves and/or byincreasing partitioning of photoassimilate to organs of economic importance.

Physiologia Plantarum, Volume 177, Issue 3, May/June 2025.ABSTRACT Previously, we produced drought‐tolerant transgenic sugarcane plants that overexpressed the AtBBX29 gene, which encodes a transcription factor (TF) B‐box protein. These plants displayed delayed senescence, were able to maintain photosynthesis, and accumulated high levels of antioxidants and osmolytes when exposed to water deficit stress ...

Glycolytic pyruvate kinase moonlighting activities in DNA replication initiation and elongation [PDF]
arXiv, 2020 Cells have evolved a metabolic control of DNA replication to respond to a wide range of nutritional conditions. Accumulating data suggest that this poorly understood control depends, at least in part, on Central Carbon Metabolism (CCM). In Bacillus subtilis , the glycolytic pyruvate kinase (PykA) is intricately linked to replication.

Biological Research, 2007 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 ...
