A natural light/dark cycle regulation of carbon-nitrogen metabolism and gene expression in rice shoots

open access: yesFrontiers in Plant Science, 2016
Light and temperature are two particularly important environmental cues for plant survival. Carbon and nitrogen are two essential macronutrients required for plant growth and development, and cellular carbon and nitrogen metabolism must be tightly ...

Nitrogen Metabolism in Senescing Leaves [PDF]

open access: yes, 1994
Leaf senescence is a highly organized process and not a passive decay. Photosynthesizing mesophyll cells lose their functions in an early phase, while the epidermal layer with the stomates and the phloem remains functional throughout senescence.

Regulatory Effect of Spermine on Growth and Antioxidant System in Tomato Seedlings Grown in the Presence of Cadmium [PDF]

open access: yesJournal of Stress Physiology & Biochemistry, 2019
The protective role of exogenous supplied polyamines such as spermine in detoxifying the cadmium induced toxicity was studied in the tomato plants Solanum lycopersicum, we applied a dose of (1 mM) spermine with cadmium (0, 20 and 100 µM) for 7 days.

The Azospirillum brasilense Core Chemotaxis Proteins CheA1 and CheA4 Link Chemotaxis Signaling with Nitrogen Metabolism

open access: yesmSystems, 2021
Bacterial chemotaxis affords motile bacteria the ability to navigate the environment to locate niches for growth and survival. At the molecular level, chemotaxis depends on chemoreceptor signaling arrays that interact with cytoplasmic proteins to control

Effect of Drought Stress at Reproductive Stages on Growth and Nitrogen Metabolism in Soybean

open access: yesAgronomy, 2020
This study aims to determine variability among soybean (Glycine max (L.) Merr.) cultivars under drought conditions and how nitrogen metabolites, metabolism-related enzymes, and gene expression vary during soybean growth.

Nitrogen phytoremediation by water hyacinth (Eichhornia crassipes (Mart.) Solms) [PDF]

open access: yes, 2008
The phytoremediation potential of water hyacinth, Eichhornia crassipes (Mart.) Solms, was examined in two independent studies under nitrogen (N) rates of 0, 40, 80, 100, 150, 200, and 300 ppm.

Nitrogen fixation in the western English Channel (NE Atlantic Ocean) [PDF]

open access: yes, 2009
In temperate Atlantic waters (18.8 to 20.1°C), biological nitrogen fixation has beendemonstrated by 2 independent measurements: 15N-N2 incorporation and nifH identification in theDNA and expressed messenger RNA (mRNA).
