Genomics and the origin of species
- O. Seehausen, R. Butlin, +31 authors A. Widmer
- Biology, Medicine
- Nature Reviews Genetics
- 1 March 2014
Speciation is a fundamental evolutionary process, the knowledge of which is crucial for understanding the origins of biodiversity. Genomic approaches are an increasingly important aspect of this… Expand
Orchid diversity: an evolutionary consequence of deception?
- S. Cozzolino, A. Widmer
- Biology, Medicine
- Trends in ecology & evolution
- 1 September 2005
The Orchidaceae are one of the most species-rich plant families and their floral diversity and pollination biology have long intrigued evolutionary biologists. About one-third of the estimated 18,500… Expand
Evolution of reproductive isolation in plants
- A. Widmer, C. Lexer, S. Cozzolino
- Biology, Medicine
- Heredity
- 2009
Reproductive isolation is essential for the process of speciation and much has been learned in recent years about the ecology and underlying genetics of reproductive barriers. But plant species are… Expand
PATTERNS OF REPRODUCTIVE ISOLATION IN MEDITERRANEAN DECEPTIVE ORCHIDS
- G. Scopece, A. Musacchio, A. Widmer, S. Cozzolino
- Biology, Medicine
- Evolution; international journal of organic…
- 1 November 2007
Abstract The evolution of reproductive isolation is of central interest in evolutionary biology. In plants, this is typically achieved by a combination of pre- and postpollination mechanisms that… Expand
The genetic architecture necessary for transgressive segregation is common in both natural and domesticated populations.
- L. Rieseberg, A. Widmer, A. Arntz, J. Burke
- Biology, Medicine
- Philosophical transactions of the Royal Society…
- 29 June 2003
Segregating hybrids often exhibit phenotypes that are extreme or novel relative to the parental lines. This phenomenon is referred to as transgressive segregation, and it provides a mechanism by… Expand
Plant centromeric retrotransposons: a structural and cytogenetic perspective
- P. Neumann, A. Navrátilová, +6 authors J. Macas
- Biology, Medicine
- Mobile DNA
- 3 March 2011
BackgroundThe centromeric and pericentromeric regions of plant chromosomes are colonized by Ty3/gypsy retrotransposons, which, on the basis of their reverse transcriptase sequences, form the… Expand
Glacial refugia: sanctuaries for allelic richness, but not for gene diversity.
Glacial refugia are generally expected to harbor higher levels of genetic diversity than are areas that have been colonized after the retreat of the glaciers because colonization often involves only… Expand
Phylogeny and classification of poison frogs (Amphibia: dendrobatidae), based on mitochondrial 16S and 12S ribosomal RNA gene sequences.
- M. Vences, J. Kosuch, +4 authors M. Veith
- Biology, Medicine
- Molecular phylogenetics and evolution
- 1 April 2000
An analysis of partial sequences of the 16S ribosomal rRNA gene (582 bp) of 20 poison frog species (Dendrobatidae) confirmed their phylogenetic relationships to bufonid and leptodactylid frogs.… Expand
Teosinte in Europe – Searching for the Origin of a Novel Weed
- Miluse Trtikova, A. Lohn, +5 authors A. Hilbeck
- Biology, Medicine
- Scientific Reports
- 8 May 2017
A novel weed has recently emerged, causing serious agronomic damage in one of the most important maize-growing regions of Western Europe, the Northern Provinces of Spain. The weed has morphological… Expand
Genome-wide Comparative Analysis of the GRAS Gene Family in Populus, Arabidopsis and Rice
- Xuanyu Liu, A. Widmer
- Biology
- Plant Molecular Biology Reporter
- 8 April 2014
GRAS genes belong to a gene family of transcription regulators that function in the regulation of plant growth and development. Our knowledge about the expansion and diversification of this gene… Expand
