“…With enhanced ozone, nitrogen concentrations in shoots of Pinus halepensis seedlings increase compared to the roots (Kytöviita et al, 2001) and N allocation is influenced in poplar cuttings under ozone fumigation by changing plant growth (Bielenberg et al, 2002). Jung et al (1994) showed a significant increase of NO 3 uptake from the soil in Picea abies seedlings after ozone fumigation. In the present study, total N in fine roots, but not in leaves, was decreased under 2 × O 3 (Fig.…”

Patterns of nitrogen (N) isotope composition (delta(15)N) and total N contents were determined in leaves, fine roots, root-associated ectomycorrhizal fungi (ECM) of adult beech trees (FAGUS SYLVATICA), and soil material under ambient (1 x O(3)) and double ambient (2 x O(3)) atmospheric ozone concentrations over a period of two years. From fine root to leaf material delta(15)N decreased consecutively. Under enhanced ozone concentrations total N was reduced in fine roots and delta(15)N showed a decrease in roots and leaves. In the soil and in most types of mycorrhizae, delta(15)N and total N were not altered due to ozone fumigation. The number of vital ectomycorrhizal root tips increased and the mycorrhizal community structure changed in 2 x O(3). Simultaneously, the specific rate of inorganic N-uptake by the roots was reduced under the double ozone regime. From these results it is assumed that 2 x O(3) changes N-nutrition of the trees at the level of N-acquisition, as indicated by enhanced mycorrhizal root tip density, altered mycorrhizal species composition, and reduced specific N-uptake rates.

“…22 The effect of the different levels of arsenic contamination on the plant metabolism was examined by means of the 15 N-tracer technique. [23][24][25][26] In plant cells, nitrogen plays an important role as a main component of amino acids, proteins and other biomolecules. Therefore, nitrogen metabolism, including the uptake and assimilation of nitrate, is one basis for an optimal biosynthesis of amino acids and proteins, which are involved in nearly all processes in plants.…”

Terrestrial plants are able to accumulate arsenic to a substantial extent but survive the stress to differing degrees of vitality. The influence of arsenic on important energy and metabolic cycles does not yet have sufficient explanation. Parallel to the uptake and processing of arsenic species such as As(III) and As(V) by Silene vulgaris, the nitrogen uptake using a 15 N tracer method was investigated. The results showed that the nitrogen uptake decreases with increasing arsenate concentrations applied to the plants. The reaction of the plants treated with arsenite changed from a depression at low arsenite concentrations to a strong increase with the largest quantity applied, exceeding the 15 N-incorporation of the control plants. This behaviour underlines the divergent behaviour of the N-metabolism caused by both arsenic species. As(III) can be detoxified by complexation with peptides rich in SH-groups. As(V) acts as a phosphate analogue and interrupts diverse phosphorylation reactions.
