Disentangling phylogenetic relationships proves challenging for groups that have evolved
recently, especially if there is ongoing reticulation. Although they are in most cases …

An overview of the diversity of vascular plants in the Czech Republic is presented. This
country is situated at the intersection of several assumed important European migration …

Background and aims Tribe Orchideae (Orchidaceae: Orchidoideae) comprises around 62
mostly terrestrial genera, which are well represented in the Northern Temperate Zone and …

Orchid species are critically dependent on mycorrhizal fungi for completion of their life cycle,
particularly during the early stages of their development when nutritional resources are …

Detailed ecological, morphological and molecular analyses were performed in mixed
populations of diploid and autotetraploid Dactylorhiza maculata sl in Scandinavia …

Background Hybridization and polyploidy are potent forces that have regularly stimulated
plant evolution and adaptation. Dactylorhiza majalis ss, D. traunsteineri sl and D. ebudensis …

To provide insights into the fate of transposable elements (TEs) across timescales in a post-
polyploidization context, we comparatively investigate five sibling Dactylorhiza …

Background Orchid species rely on mycorrhizal symbioses with fungi to complete their life
cycle. Although there is mounting evidence that orchids can associate with several fungi …

Although polyploidy plays a fundamental role in plant evolution, the elucidation of polyploid
origins is fraught with methodological challenges. For example, allopolyploid species may …

The digitate-tubered clade (Dactylorhiza sl plus Gymnadenia sl) within subtribe Orchidinae
