Nitrate alleviates ammonium toxicity in Brassica napus by coordinating rhizosphere and cell pH and ammonium assimilation.

In natural and agricultural situations, ammonium ( ) is a preferred nitrogen (N) source for plants, but excessive amounts can be hazardous to them, known as toxicity. Nitrate ( ) has long been recognized to reduce toxicity. However, little is known about Brassica napus, a major oil crop that is sensitive to high .

Photodegradation of glyphosate in water and stimulation of by-products on algae growth.

Glyphosate is the most widely used herbicide in global agricultural cultivation. However, little is known about the environmental risks associated with its migration and transformation. We conducted light irradiation experiments to study the dynamics and mechanism of photodegradation of glyphosate in ditches, ponds and lakes, and evaluated the effect of glyphosate photodegradation on algae growth through algae culture experiments.
