Population history, genetic variation, and conservation status of European white elm ( Pall.) in Poland.

Key Message: The core populations of the European white elm ( Pall.) located in Poland maintained slightly higher level of genetic diversity compared to the peripheral populations of this species.

Context: The most severe threat to elms is the loss of natural habitat under the pressures of agriculture and forestry as well as urbanization.

Epigenetic Marks, DNA Damage Markers, or Both? The Impact of Desiccation and Accelerated Aging on Nucleobase Modifications in Plant Genomic DNA.

Modifications of DNA nucleobases are present in all forms of life. The purpose of these modifications in eukaryotic cells, however, is not always clear. Although the role of 5-methylcytosine (mC) in epigenetic regulation and the maintenance of stability in plant genomes is becoming better understood, knowledge pertaining to the origin and function of oxidized nucleobases is still scarce.

Current and potential distribution of the ectomycorrhizal fungus Suillus lakei ((Murrill) A.H. Sm. & Thiers) in its invasion range.

Suillus lakei is an ectomycorrhizal fungus native to North America and known in Europe, South America, and New Zealand. This contribution aims to illustrate the worldwide biogeography of S. lakei based on sporocarp records.

Contrasting patterns of genetic variation in core and peripheral populations of highly outcrossing and wind pollinated forest tree species.

Gene flow tends to have a homogenising effect on a species' background genetic variation over large geographical areas. However, it is usually unknown to what extent the genetic structure of populations is influenced by gene exchange between core and peripheral populations that may represent stands of different evolutionary and demographic history. In this study, we looked at the patterns of population differentiation in Scots pine-a highly outcrossing and wind pollinated conifer species that forms large ecosystems of great ecological and economic importance in Europe and Asia.

Functional characterization of a dehydrin protein from Fagus sylvatica seeds using experimental and in silico approaches.

A strong increase in the level of dehydrin/response ABA transcripts expression reported from the 14th week after flowering coincident with the accumulation of 26 and 44 kDa dehydrins in the embryonic axes of developing beech (Fagus sylvatica L.) seeds. Both transcript and protein levels were strongly correlated with maturation drying.
