Stable Epigenetic Effects Impact Adaptation in Allopolyploid Orchids (Dactylorhiza: Orchidaceae)
Epigenetic information includes heritable signals that modulate gene expression but are not encoded in the primary nucleotide sequence. We have studied natural epigenetic variation in three allotetraploid sibling orchid species (Dactylorhiza majalis s.str, D. traunsteineri s.l., and D. ebudensis) that differ radically in geography/ecology. The epigenetic variation released by genome doubling ha...
متن کاملDactylorhiza (Orchidaceae) in European Russia: combined molecular and morphological analysis.
Four plastid and two nuclear (internal transcribed spacer [ITS] ribosomal DNA) markers were used in this study of the Dactylorhiza maculata and D. incarnata complexes (Orchidaceae: Orchidinae) to determine diversity and taxonomic distribution of haplotypes, hybridization frequencies, and maternal parentage of hybrids in 125 samples from 78 populations from European Russia and the Caucasus. A mo...

15 صفحه اولPlastid DNA variation in the Dactylorhiza incarnata/maculata polyploid complex and the origin of allotetraploid D. sphagnicola (Orchidaceae).
To obtain further information on the polyploid dynamics of the the Dactylorhiza incarnata/maculata polyploid complex and the origin of the allotetraploid D. sphagnicola (Orchidaceae), plastid DNA variation was studied in 400 plants from from Sweden and elsewhere in Europe and Asia Minor by means of polymerase chain reaction-restriction fragment length polymorphisms (PCR-RFLPs) and sequencing. A...
متن کاملPhylogenetic relationships in Epidendroideae (Orchidaceae), one of the great flowering plant radiations: progressive specialization and diversification.
BACKGROUND AND AIMS The largest subfamily of orchids, Epidendroideae, represents one of the most significant diversifications among flowering plants in terms of pollination strategy, vegetative adaptation and number of species. Although many groups in the subfamily have been resolved, significant relationships in the tree remain unclear, limiting conclusions about diversification and creating u...
