The technology is now in place for major advances in the genetics and cytogenetics of fishes
at the molecular level. One promising method with broad application is fluorescence in situ …

We investigated concerted evolution of rRNA genes in multiple populations of Tragopogon
mirus and T. miscellus, two allotetraploids that formed recurrently within the last 80 years …

Background Polyploidy, frequently termed “whole genome duplication”, is a major force in
the evolution of many eukaryotes. Indeed, most angiosperm species have undergone at …

Here, we analyze long‐term evolution in Nicotiana allopolyploid section Repandae (the
closest living diploids are N. sylvestris, the maternal parent, and N. obtusifolia, the paternal …

A group of monocotyledonous plants within the order Asparagales, forming a distinct clade
in phylogenetic analyses, was reported previously to lack the 'typical'Arabidopsis–type …

Using slot‐blot and fluorescent in situ hybridization (FISH), we found no evidence for the
presence of the Arabidopsis‐type telomeric sequence (TTTAGGG) n at the chromosome …

We examined the structure, intranuclear distribution and activity of ribosomal DNA (rDNA) in
Nico-tiana sylvestris (2 n= 2 x= 24) and N. tomentosiformis (2 n= 2 x= 24) and compared …

Nicotiana tabacum (tobacco) is an allotetraploid derived from ancestors of the modern
diploids, N. sylvestris and N. tomentosiformis. We identified and characterized two distinct …

Typically in plants, the 5S and 35S ribosomal DNA (rDNA) encoding two major ribosomal
RNA species occur at separate loci. However, in some algae, bryophytes and ferns, they are …

Cynipid gall formation is achieved by an insect–plant interaction whereby cynipid gallwasps
redirect host‐plant development to form novel structures to protect and nourish the …
