Organic and inorganic nitrogen play important roles in plant nutrition. However, how the coapplication of organic affects root growth, metabolism, soil content is still unclear. Plant shoot uptake were studied maize (Zea mays L.) through pot experiments with different treatments, including NH4+ -N (Amm), NO3− (Nit), + (Amm Nit), glutamate-N Nit Glu), glycine-N Gly). The results show that treate...

A psychrotolerant marine bacterial strain, designated JUB59(T), was isolated from Antarctic surface seawater and classified as a new species of the genus Bizionia. Here, we present the first draft genome sequence for this genus, which suggests interesting features such as UV resistance, hydrolytic exoenzymes, and nitrogen metabolism.

The possibility of the changes in the proteolytic system that may be brought about by certain therapeutic substances has been studied in the present paper. The changes in the trypsin content of blood in certain pathological conditions have been reported by Iyengar et al. (1942). From these experiments it was considered likely that changes in the trypsin content may be reliable index of changes ...

Soybean (Glycine max) seeds store significant amounts of their biomass as protein, levels of which reflect the carbon and nitrogen received by the developing embryo. The relationship between carbon and nitrogen supply during filling and seed composition was examined through a series of embryo-culturing experiments. Three distinct ratios of carbon to nitrogen supply were further explored through...

In a contribution to this Research Topic Erkki Somersalo and Daniela Calvetti carried out a mathematical analysis of neurotransmitter pathways in brain, modeling compartmental nitrogen flux among several major participants - ammonia, glutamine, glutamate, GABA, and selected amino acids. This analysis is important because cerebral nitrogen metabolism is perturbed in many diseases, including live...

to examine the effects of different sources of rumen-degradable carbohydrates on rumen fermentation, nitrogen metabolism and performance of holstein dairy cows, four lactating holstein cows fitted with rumen cannulae in a 4×4 latin square with four diets and four 28 day periods each, were employed. experimental diets contained different levels of pure sucrose and corn starch in which sucrose wa...
