Sulfur affects root growth and improves nitrogen recovery and internal efficiency in wheat
Wheat plants were cultivated in pots with the objective of evaluating the effect of two sulfur (S) rates (+S and −S) on (i) shoot growth, S and nitrogen (N) uptake and nitrogen use efficiency (NUE) and (ii) root growth and ...
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 ...
Potential Root Depth Development and Nitrogen Uptake by Tetraploid Bahiagrass Hybrids
(Springer Wien, 2010-04-27)
The objectives were to develop a screening technique to evaluate the tetraploid germplasm ofPaspalum notatum Flüggé (bahiagrass) for potential rate of root depth development (RRDD), estimate the variability for RRDD among ...
Relative importance of biological nitrogen fixation and mineral uptake in high yielding soybean cultivars
Backgrounds and aims: Soybean yield depends on total N uptake, N use efficiency, and harvest index. Nitrogen uptake relays on biological fixation (BNF) and soil absorption. Usually, BNF is considered a yield-related process. ...
Nitrogen dynamics in the intact grasses Poa trivialis and Panicum maximum receiving contrastaing suplies of nitrogen.
(Journal of Experimental Botany, v.53, n.387, p.2167-2176, Nov. 2002., 2011)
The GATA-type transcriptional activator Gat1 regulates nitrogen uptake and metabolism in the human pathogen Cryptococcus neoformans
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2011)
Nitrogen uptake and metabolism are essential to microbial growth. Gat1 belongs to a conserved family of zinc finger containing transcriptional regulators known as GATA-factors. These factors activate the transcription of ...
Effect of phosphorus and nitrogen fertilization on sunflower (Helianthus annus L.) nitrogen uptake and yield
(Wiley Blackwell Publishing, Inc, 2002-08)
Little is known about the effect of combined phosphorus and nitrogen (P-N) fertilization on the N requirement of sunflower (Helianthus annus L.). This study was carried out to evaluate the effects of varying levels of P ...
