A model by which plants adapt their photosynthetic metabolism to light intensity

Researchers proposed a model explaining how plants regulate photosynthesis in response to varying light intensities through redox systems like thioredoxins and NTRC. The chloroplasts have protective antioxidant enzymes, such as 2-cys peroxiredoxin, which play a crucial role in maintaining the balance of these redox systems.

Pesticides persist in ground water

USGS scientists investigated pesticide occurrence in ground water at four US sites. Herbicides triazines and chloroacetanilides were most frequently detected, with degradation products often exceeding parent compounds. Redox conditions, residence times, oxygen levels, and nitrogen gas influenced pesticide concentrations.
