Nitrogen fertilizer rate but not form affects the severity of Fusarium wilt in banana

Frontiers in Plant Science, 2022
Nitrogen (N) fertilizers are routinely applied to bananas (Musa spp.) to increase production but may exacerbate plant diseases like Fusarium wilt of banana (FWB), which is the most economically important disease.

Long-term monitoring reveals carbon-nitrogen metabolism key to microcystin production in eutrophic lakes

Frontiers in Microbiology, 2015
The environmental drivers contributing to cyanobacterial dominance in aquatic systems have been extensively studied. However, understanding of toxic versus non-toxic cyanobacterial population dynamics and the mechanisms regulating cyanotoxin production ...

Redox-Controlled Ammonium Storage and Overturn in Ediacaran Oceans

Frontiers in Earth Science, 2021
As a key nutrient, nitrogen can limit primary productivity and carbon cycle dynamics, but also evolutionary progress. Given strong redox-dependency of its molecular speciation, environmental conditions can control nitrogen localization and ...

Biological Activity of Quaternary Ammonium Salts and Their Derivatives

Pathogens, 2020
Besides their positive role, microorganisms are related to a number of undesirable effects, including many diseases, biodeterioration and food spoilage, so when their presence is undesired, they must be controlled.
