Plant growth‐promoting bacteria (PGPB) and NO–3 availability both affect NO–3 uptake and
root architecture. The presence of external NO–3 induces the expression of NO–3 …

Nitrogen (N) metabolism is of great economic importance because it provides proteins and
nucleic acids which in turn control many cellular activities in plants. Salinity affects different …

Box 9E. 1 Continued FIGURE 2. The C–S–R triangle model (Grime 1979). The strategies at
the three corners are C, competiti-winning species; S, stress-tolerating s-cies; R …

This is a completely revised edition of the previously titled Solute Movement in the Soil-Root
System. It describes in detail how plant nutrients and other solutes move in the soil in …

The concept of critical nitrogen concentration (% N c) has been proposed as the minimum%
N in shoots required to produce the maximum aerial biomassat a given time. Several …

▪ Abstract Nitrate is the major source of nitrogen (N) for plants growing in aerobic soils.
However, the NO3− ion is also used by plants as a signal to reprogram plant metabolism …

In the last 40 years, the global use of mineral N fertilizers has increased to support
increasing food demand. Misuse of fertilizer has led to environmental problems in some …

Nitrogen is the mineral nutrient that plants need in the greatest quantities and the one that
most frequently limits plant growth and crop yields. Most plants get their nitrogen (N) from the …

The activity of ATP sulfurylase extracted from roots of intact canola (Brassica napus L. cv
Drakkar) increased after withdrawal of the S source from the nutrient solution and declined …

Sulfate uptake and ATP sulfurylase activity in the roots of Arabidopsis thaliana and Brassica
napus were enhanced by S deprivation and reduced following resupply of SO42–. Similar …
