cytochrome oxidase/zea mays

Cross hybridization between maize mitochondrial DNA fragments and a specific yeast mitochondrial DNA probe from the oxi 1 gene has been used to identify and isolate the maize mitochondrial gene coding cytochrome oxidase subunit II, mox 1. The DNA sequence reveals two coding regions separated from

A restriction endonuclease fragment of the maxicircle of Trypanosoma brucei brucei kinetoplast DNA hybridizes with a cloned mitochondrial DNA sequence which encodes cytochrome oxidase subunit II of Zea mays. A cloned mitochondrial DNA sequence encoding cytochrome oxidase subunit II of Saccharomyces

The coding and flanking sequences of the 18S-5S ribosomal RNA genes and the cytochrome oxidase subunit II gene of Zea diploperennis mitochondrial DNA have been determined and compared to the corresponding sequences of normal maize (Zea mays L.) Both length and substitution mutations are found in the

The cytochrome oxidase subunit II gene has been localized in the mitochondrial genome of Oenothera berteriana and the nucleotide sequence has been determined. The coding sequence contains 777 bp and, unlike the corresponding gene in Zea mays, is not interrupted by an intron. No TGA codon is found

Cytochemical changes during the early development of maize caryopsis are reported. Changes in the localization of different reserve substances (e.g. polysaccharides, proteins, nucleic acids and lipids) and enzymes (acid phosphatase, esterase, lipase, phosphorylase, succinate dehydrogenase,

Foliar applications of 2 milligrams per liter of 2-chloro-4,6-bis (ethylamino)-s-triazine, 2-methylmercapto-4-ethylamino-6-isobutylamino-s-triazine, and 2-methoxy-4-isopropylamino-6-butylamino-s-triazine caused increases in the activities of starch phosphorylase, pyruvate kinase, cytochrome oxidase,

Several restriction sites in the cytochrome oxidase I gene of fall armyworm, Spodoptera frugiperda (J.E. Smith), were identified by sequence analysis as potentially being specific to one of the two host strains. Strain specificity was demonstrated for populations in Florida, Texas, Mississippi,

The mechanism of cytoplasmic male sterility was investigated in maize by isolating mitochondria from seedlings and various anther stages and analyzing cytochrome oxidase and succinic dehydrogenase biochemically and electrophoretically. Sterile anthers exhibited a lack of biochemical activity and

Aphids are major vectors of plant viruses. Common bean (Phaseolus vulgaris L.) and maize (Zea mays L.) are important crops that are vulnerable to aphid herbivory and aphid-transmitted viruses. In East and Central Africa, common bean is frequently intercropped by smallholder farmers to provide fixed

The ATPase subunit 6, located in the inner mitochondrial membrane, is encoded by mitochondrial genomes in animals and fungi. We have isolated and characterized a mitochondrial gene, designated atp 6, that encodes the subunit 6 polypeptide of Zea mays. Nucleotide and predicted amino acid sequence

The development of enzyme patterns was followed in the course of: (a) the irreversible cell differentiation via division and expansion to maturity in the root tip and coleoptile of the intact seedlings, (b) the irreversible cell dedifferentation associated with induction and establishment of callus

Mitochondria execute key pathways of central metabolism and serve as cellular sensing and signaling entities, functions that depend upon interactions between mitochondrial and nuclear genetic systems. This is exemplified in cytoplasmic male sterility type S (CMS-S) of Zea mays, where novel

Taking into account the sexual dimorphism previously found in white adipose tissue (WAT) regarding mitochondrial function and biogenesis, as well as insulin sensitivity, the aim of this study was to go further into the role of sex hormones in this dimorphism. To achieve this objective, we used

The effects of feeding high fat diets on thermogenesis in brown adipose tissue has been investigated in cold-acclimated mice. Two high fat diets of differing fatty acid composition were used, one of which was based on corn oil and the other on beef tallow. After 3 weeks of feeding the diets there
