A Metabolic Widget Adjusts the Phosphoenolpyruvate-Dependent Fructose Influx in Pseudomonas putida
Fructose uptake in the soil bacterium Pseudomonas putida occurs through a canonical phosphoenolpyruvate (PEP)-dependent sugar transport system (PTSFru). The logic of the genetic circuit that rules its functioning is puzzling: ...
Regulation of Zn and Fe transporters by the GPC1 gene during early wheat monocarpic senescence
(BioMed Central, 2014-02)
BACKGROUND: During wheat senescence, leaf components are degraded in a coordinated manner, releasing amino acids and micronutrients which are subsequently transported to the developing grain. We have previously shown that ...
Genome-wide identification, classification and transcriptional analysis of nitrate and ammonium transporters in Coffea
Nitrogen (N) is quantitatively the main nutrient required by coffee plants, with acquisition mainly by the roots and mostly exported to coffee beans. Nitrate (NO3 -) and ammonium (NH4 +) are the most important inorganic ...

El estudio tuvo como objetivo evaluar el efecto de las características de las plantas y los rasgos funcionales de la copa de árboles: Albizia saman, Coccoloba caracasana, Coccoloba floribunda, Crescentia alata, Enterolobium ...
Fontes orgânicas e Mineral: produção de culturas, alteração nos atributos químicos do solo e transferência de formas de nitrogênio e de fósforo
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Ciência do Solo, 2015-03-30)
The pig slurry, pig deep-litter and cattle slurry applied in soils under no-tillage can serve as a source of nutrients for crops, increasing the production of dry matter of shoots and grain production. This is because, ...
O papel da competição por luz e da troca de nutrientes na interação entre plantas
(Universidade Federal de Santa MariaBRFísicaUFSMPrograma de Pós-Graduação em Física, 2003-12-03)
At this work we present two models to describe de growth dynamics of interacting plants. The first system that we have used describes de water dynamics, and then relates it with the cations in the ground and with the biomass ...
Tidal time-scale variation of inorganic nutrients and organic matter in Bahia Blanca mesotidal estuary, Argentina
(Taylor & Francis, 2009-12)
Land-derived materials are regulated by coastal and shelf environmental conditions before being transported to the open sea. It is of great concern to understand the processes and to establish the extent in which they ...
Efecto de la acidez de los suelos en el normal crecimiento y desarrollo de tres especies de pastos
(Universidad Nacional Agraria La Molina, 2016)
