Biochemical and structural characteristics of Scots pine (Pinus sylvestris L.) in an alkaline environment
Investigations in a 7585-year-old Scots pine stand were performed on a territory influenced over 40 years by alkaline dust pollution (pH 12.312.7) emitted from a cement plant. Sample plots were located at distances of 2, 3, and 5 km E of the emission source and a control sample plot was selected on an unpolluted territory 38 km W of it. We studied soil properties and the anatomical structure,...
متن کاملGene-pool variation in caledonian and European Scots pine (Pinus sylvestris L.) revealed by chloroplast simple-sequence repeats.
We have used polymorphic chloroplast simple-sequence repeats to analyse levels of genetic variation within and between seven native Scottish and eight mainland European populations of Scots pine (Pinus sylvestris L.). Diversity levels for the Scottish populations based on haplotype frequency were far in excess of those previously obtained using monoterpenes and isozymes and confirmed lower leve...
متن کاملCharacterization of a Lhcb5 cDNA from Scots pine (Pinus sylvestris).
Despite extensive studies on the LHC proteins of PSI and PSII (for review, see Jansson, 1994), the detailed polypeptide composition of LHC I and LHC I1 has not been understood until recently. The nature of the Lhcb5 gene product has been one of the major uncertainties, since it has been identified both as the CP26 (or the equivalent complex LHCIIc) polypeptide and one of two CP29 polypeptides (...
متن کاملPeculiar traits of wood in a leaning stem of Scots pine (Pinus sylvestris L.)
The paper analyses biometrical and anatomical traits of wood in a leaning stem of pine trees. For study purpose, five pine trees (Pinus sylvestris L.) with a visibly leaning stem were chosen. Wood samples were taken at three different stem heights, that is, below the stem curvature, at the curvature and above the curvature. Microscopic specimens were prepared and used for the following measurem...
متن کاملFungal Infection Increases the Rate of Somatic Mutation in Scots Pine (Pinus sylvestris L.).
Somatic mutations are transmitted during mitosis in developing somatic tissue. Somatic cells bearing the mutations can develop into reproductive (germ) cells and the somatic mutations are then passed on to the next generation of plants. Somatic mutations are a source of variation essential to evolve new defense strategies and adapt to the environment. Stem rust disease in Scots pine has a negat...
