A Zea mays 39-kDa thylakoid transglutaminase catalyses the modification by polyamines of light-harvesting complex II in a light-dependent way.

Only registered users can translate articles

A transglutaminase (TGase; EC 2.3.2.13) activity, which shared many properties with the TGase activity of the Helianthus tuberosus chloroplast, was observed in the Zea mays L. chloroplast and in its fractions. This activity was found to be prevalent in thylakoids; bis-(glutamyl) spermidine and

Effect of Exogenous Putrescine, Spermidine, and Spermine on K Uptake and H Extrusion through Plasmamembrane in Maize Root Segments.

Only registered users can translate articles

The action of exogenous polyamines (putrescine, spermidine, and spermine) on ;washing' and fusicoccin-stimulated K(+) uptake and H(+) extrusion through the plasmamembrane in maize (Zea mays L., hybrid line Plenus S 516) root apical segments was studied. The results showed that polyamines inhibit the

Modulation of spermidine and spermine levels in maize seedlings subjected to long-term salt stress.

Only registered users can translate articles

Salinity is one of the major abiotic stresses affecting plant agriculture worldwide. Polyamines, a group of aliphatic amines, are known to accumulate under salt stress conditions in different plant systems, resulting in presumed protective effects, acting as free radical scavengers, stabilizing

Nocardioides zeae sp. nov., isolated from the stem of Zea mays.

Only registered users can translate articles

A Gram-stain-positive aerobic organism, isolated from the healthy stem of a Zea mays plant was studied for its taxonomic position. Based on 16S rRNA gene sequence analysis strain JM-1068(T) was most closely related to Nocardioides alkalitolerans (97.2%). The 16S rRNA gene sequence similarity to all

tRNA isopentenyltransferase from Zea mays L. Characterization of the isopentenylation reaction of tRNA, oligo (A) and other nucleic acids.

Only registered users can translate articles

The extraction and purification of the tRNA isopentenyltransferase from maize root tips and kernels are reported. The relative amounts of this enzyme in different organs of maize have been determined. Root tips have the highest enzyme activities, followed by kernels and young leaves. Old leaves

Polyamine-stimulated phosphorylation of proteins from corn (Zea mays L.) coleoptiles.

Only registered users can translate articles

The effect of polyamines (spermine, spermidine and putrescine) on in vitro phosphorylation of proteins from corn coleoptiles was investigated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and autoradiography. Spermine promoted the phosphorylation of several membrane and soluble

Pseudogracilibacillus auburnensis gen. nov., sp. nov., isolated from the rhizosphere of Zea mays.

Only registered users can translate articles

A Gram-positive-staining, aerobic, endospore-forming bacterium, strain P-207(T), was isolated from a rhizosphere soil sample in Auburn, AL, USA. On the basis of 16S rRNA gene sequence comparisons, strain P-207(T) was grouped in the vicinity of representatives of the genera Virgibacillus,

Crystallization and preliminary X-ray analysis of polyamine oxidase from Zea mays L.

Only registered users can translate articles

Polyamine oxidase catalyses the oxidation of the secondary amino group of spermine, spermidine and their acetyl derivatives. The enzyme plays an important role in the regulation of polyamine intracellular concentration and is a member of the family of flavin-containing amine oxidases. Crystals of

Comparative analysis of polyamine metabolism in wheat and maize plants.

Only registered users can translate articles

In the present work changes in polyamine contents were investigated after various hydroponic polyamine treatments (putrescine, spermidine and spermine at 0.1, 0.3 and 0.5 mM concentrations) in two different crop species, wheat and maize. In contrast to putrescine, higher polyamines (spermidine and

Transport Interactions between Paraquat and Polyamines in Roots of Intact Maize Seedlings.

Only registered users can translate articles

Interactions between absorption of paraquat and the polyamines putrescine, cadaverine, and spermine in roots of intact maize (Zea mays L. cv 3377 Pioneer) seedlings were examined. Concentration-dependent kinetics for paraquat and putrescine influx were similar and both kinetic curves could be

Effect of deltamethrin on regional brain polyamines and behaviour in young rats.

Only registered users can translate articles

The present study examines the mechanism of neurotoxic action of a synthetic pyrethroid formulation deltamethrin in young rats. Newly weaned Wistar Albino male rats received deltamethrin of technical grade at a dose of 7.0 mg/kg body weight/day in corn oil, orally from postnatal day 22 to postnatal

Roles of carbohydrate supply and ethylene, polyamines in maize kernel set.

Only registered users can translate articles

Glucose appears to have an antagonistic relationship with ethylene and ethylene and polyamines appear to play antagonistic roles in the abortion of seeds and fruits. Moreover, ethylene, spermidine, and spermine share a common biosynthetic precursor. The synchronous changes of them and the

Activities of arginine and ornithine decarboxylases in various plant species.

Only registered users can translate articles

In extracts from the youngest leaves of Avena sativa, Hordeum vulgare, Zea Mays, Pisum sativum, Phaseolus vulgaris, Lactuca sativa, and four pyrrolizidine alkaloid-bearing species of Heliotropium, the activities of ornithine decarboxylase, close to V(max), ranged between traces and 1.5 nanomoles per

Ornithine decarboxylase and thymidine kinase activities and polyamine levels from selected organs of adult miniature swine receiving three concentrations of dietary menhaden oil.

Only registered users can translate articles

Mature, female swine were randomly assigned to one of seven dietary groups. Swine in groups 1-3 were fed a cholesterol-rich diet for 55 days while the remaining groups remained on a basal swine diet. At the end of the cholesterol(Chol)-preloading period the swine in groups 1-7 were placed on

Studies on the Processivity of Maize DNA Polymerase 2, an [alpha]-Type Enzyme.

Only registered users can translate articles

This paper describes studies on the processivity of an [alpha]-type DNA polymerase from maize (Zea mays L.) embryonic axes, designated as DNA polymerase 2. Using poly(dA)/oligo(dT) as template, DNA polymerase 2 has a processivity of 18 ([plus or minus]5) nucleotides incorporated, a value much lower
