Phytochemicals in vegetables are important for human health, and their biosynthesis,
metabolism and accumulation are affected by environmental factors. Light condition (light …

Secondary metabolism in plants is considerably affected by environmental factors including
mineral nutrition. Nitrogen is a key plant nutrient, known to affect primary and secondary …

Ammonium (NH4+) toxicity is an issue of global ecological and economic importance. In this
review, we discuss the major themes of NH4+ toxicity, including the occurrence of NH4+ in …

Across Europe, total nitrogen deposition is increasing and, of this total, atmospheric
ammonia can contribute up to 50–80%. Average deposition of ammonia in the UK is likely to …

Nitrate and ammonium have different effects on many biochemical and physiological
processes in plants, and at high concentrations this can lead to markedly different growth …

Nitrogen (N) and potassium (K) are the two most abundantly acquired mineral elements by
plants, and their acquisition pathways interact in complex ways. Here, we review pivotal …

Ammonium and nitrate as different forms of nitrogen nutrients impact differently on some
physiological and biochemical processes in higher plants. Compared to nitrate, ammonium …

The effect of salinity (100 mM NaCl) and different nitrogen sources (NaNO3/(NH4) 2SO4) on
the activity and spatial distribution of antioxidative enzymes (glutathione reductase, GR; …

Blueberry, raspberry and strawberry may have evolved strategies for survival due to the
different soil conditions available in their natural environment. Since this might be reflected …
