Development of cytosine and adenine base editors for maize precision breeding

Journal of Integrative Plant Biology, EarlyView.
A series of maize cytosine and adenine base editors was developed using various deaminase variants, enabling efficient multiplex genome editing in maize. Precise editing of the ZmACC1/2 genes generated herbicide‐tolerant maize germplasm, offering a solution for weed management in maize‐soybean intercropping systems.

Kalymmatonema gen. nov. (Scytonemataceae, Cyanobacteria): A desert soil crust genus previously identified as Scytonema hyalinum, with description of seven species new to science

Journal of Phycology, EarlyView.
Abstract Numerous cyanobacterial strains previously identified as Scytonema hyalinum were determined to be phylogenetically distant from the type species of Scytonema, S. hofmannii. Morphological and molecular evidence suggests this distinct clade necessitates placement in a new genus, and we have described Kalymmatonema gen. nov. herein. Kalymmatonema

Adenine nucleotides in blood

Biochemical Medicine, 1970
Abstract A new, dynamic cycling procedure for total adenine nucleotides (ATP + ADP + AMP) is described. This procedure permits the measurement of adenine nucleotides in TCA extracts of fresh or frozen blood samples without requiring the removal of TCA from extract.

Adenine nucleotides and ventricular fibrillation

Journal of Molecular and Cellular Cardiology, 1987
The isolated perfused rat heart was used to study the influence of adenine nucleotides and their metabolites on vulnerability to ventricular fibrillation. In this model the incidence of ventricular arrhythmias after coronary artery ligation is determined by the extracellular K+ concentration; with perfusate K+ of 2.0 and 3.0 mmol/l hearts develop a ...

Measurement of adenine nucleotides in plasma

Luminescence, 2003
AbstractThe goal of this study was to identify the most important variables affecting bioluminescent ATP, ADP and AMP measurements in plasma and to develop an assay that takes these variables into account. Blood samples were drawn from conscious dogs.

The adenine nucleotide translocator in apoptosis

Biochimie, 2002
Alteration of mitochondrial membrane permeability is a central mechanism leading invariably to cell death, which results, at least in part, from the opening of the permeability transition pore complex (PTPC). Indeed, extended PTPC opening is sufficient to trigger an increase in mitochondrial membrane permeability and apoptosis.

A new adenine nucleotide

Biochimica et Biophysica Acta, 1953
Abstract A new nucleotide has been shown to be present in commercial samples of adenosine-5′-triphosphate (ATP). The analytical data suggest the structure adenosine-5′-tetraphosphate.

Reactions of Dysprosium with Adenine Nucleotides

Journal of Inorganic Biochemistry, 1988
Dysprosium catalyzes a rapid hydrolysis of both ATP and ADP, at ambient temperatures, pH 7.0, where no hydroxide precipitates. The reactive complexes, at pH 6.7, were found to contain 2Dy:1ATP and 3Dy:2ADP. AMP forms an insoluble complex containing 1Dy:2AMP, which does not hydrolyze.

Adenine nucleotides of the stria vascularis

Archives of Oto-Rhino-Laryngology, 1979
The levels of the adenine nucleotides ATP, ADP, and AMP in the stria vascularis were measured under normal conditions, and following various durations of ischemia. The concentrations of these compounds were used for the calculation of the adenylate energy charge, the energy status and the phosphorylation state of the stria. Following 10 min of ischemia
