Non-inoculated plants displayed comparable growth profiles to those of inoculated plants (data not shown) in function of time and N supply. The roots exhibited similar profiles to the aerial parts, except at 42 dpi in both N conditions where HD had a slightly higher weight than Y. Thus, there was no important effect of genotype but a high ...

Tissue and nitrogen-linked expression profiles of

Nitrogen is an essential nutrient required for plant growth. It is a primary constituent of nucleic acids, amino acids and proteins. Although 78% of the atmospheric air is made of N 2, only legumes are able to convert atmospheric N 2 to plant available forms of nitrogen via a symbiotic biological process involving Rhizobium bacteria resident in …

Plant nitrogen (N), acquired mainly in the form of nitrate and ammonium from soil, dominates growth and development, and high-yield crop production relies …

Precipitation and plant functional composition mediate

Background and aims Plant nutrients play a fundamental role in regulating ecosystem functioning and are sensitive to global changes such as precipitation change and nitrogen (N) deposition. However, the mechanisms by which resource availability and community composition mediate canopy nutrients remain unclear. Methods We …

Nitrogen supply affects cannabinoid and terpenoid profile …

Nitrogen is a key plant nutrient, known to affect primary and secondary metabolism in plants, that its effect on the cannabis plants' chemical profile is not known. To evaluate the hypothesis that N supply affects the cannabinoid and terpenoid profile, we studied the impact of N application on chemical and functional-physiology phenotyping in ...
