Arabidopsis Growth-Promotion and Root Architecture Responses to the Beneficial Rhizobacterium Phyllobacterium brassicacearum Strain STM196 Are Independent of the Nitrate Assimilatory Pathway

Plants, 2022
Phyllobacterium brassicacearum STM196, a plant growth-promoting rhizobacterium isolated from roots of oilseed rape, stimulates Arabidopsis growth. We have previously shown that the NRT2.5 and NRT2.6 genes are required for this growth promotion response ...

The dependence of nitrate reductase activity on the level of soluble sugars in wheat and cucumber roots growing in the presence of simazine, in light or in darkness

Acta Societatis Botanicorum Poloniae, 2014
At concentrations of 25 and 5 µM, simazine inhibited nitrate reductase activity in wheat and cucumber roots, respectively. It also lowered the content of soluble sugars and decreased the activities of NADH malate dehydrogenase and NADP+ glucose-6 ...

Low time resolution analysis of polar ice cores cannot detect impulsive nitrate events [PDF]

Journal of Geophysical Research: Space Physics 119, 9430-9440 (2014), 2015
Ice cores are archives of climate change and possibly large solar proton events (SPEs). Wolff et al. (2012) used a single event, a nitrate peak in the GISP2-H core, which McCracken et al. (2001a) time associated with the poorly quantified 1859 Carrington event, to discredit SPE-produced, impulsive nitrate deposition in polar ice.

Miniview: algal nitrate reductases [PDF]

European Journal of Phycology, 1997
The past decade has seen substantial breakthroughs in understanding the biochemistry, molecular biology and regulation of nitrate reductases (NR) in higher plants and green algae. In contrast, although there has been considerable interest in using various measurements of NR to provide ecophysiological information, comparable knowledge of NR is largely ...

Orphan response regulator NnaR is critical for nitrate and nitrite assimilation in Mycobacterium abscessus

Frontiers in Cellular and Infection Microbiology
Mycobacterium abscessus (Mab) is an opportunistic pathogen afflicting individuals with underlying lung disease such as Cystic Fibrosis (CF) or immunodeficiencies.

Soil acidity as affecting micronutrients concentration, nitrato reductase enzyme activity and yield in upland rice plants

Semina: Ciências Agrárias, 2013
The lowest grain yield of rice under no-tillage system (NTS) in relation to the conventional system may be due to the predominance nitrate in the soil and the low nitrate reductase activity.

Clustering as a Means To Control Nitrate Respiration Efficiency and Toxicity in Escherichia coli

mBio, 2019
Respiration is a fundamental process that has to optimally respond to metabolic demand and environmental changes. We previously showed that nitrate respiration, crucial for gut colonization by enterobacteria, is controlled by polar clustering of the ...

New insights into the role of chrysanthemum calcineurin B–like interacting protein kinase CmCIPK23 in nitrate signaling in Arabidopsis roots

Scientific Reports, 2022
Nitrate is an important source of nitrogen and also acts as a signaling molecule to trigger numerous physiological, growth, and developmental processes throughout the life of the plant.

Huge Seebeck coefficients in non-aqueous electrolytes [PDF]

, 2011
The Seeebeck coefficients of the non-aqueous electrolytes tetrabutylammonium nitrate, tetraoctylphosphonium bromide and tetradodecylammonium nitrate in 1-octanol, 1-dodecanol and ethylene-glycol are measured in a temperature range from T=30 to T=45 C.

Nitrate and nitrite reductase activities of Mycobacterium avium

International Journal of Mycobacteriology, 2018
Background: In spite of the fact that the standard test for nitrate reductase activity is negative for Mycobacterium avium, it can grow in a defined minimal medium with either nitrate (NO3) or nitrite (NO2) as sole nitrogen sources.
