Evolution of Iris subgenus Xiphium based on chromosome numbers, FISH of nrDNA (5S, 45S) and trnL–trnF sequence analysis
The subgenus Xiphium is one of the six infrageneric divisions of the genus Iris. Chromosome numbers of six of the seven Xiphium species are known. Here the aim was to infer genetic and phylogenetic… Expand

Karyotype evolution and cytotaxonomy in Brazilian species of Rhynchospora Vahl (Cyperaceae)
Abstract Karyotypes were analysed in 113 populations of 34 species of Rhynchospora (Cyperaceae). They showed typical holocentric chromosomes lacking primary constrictions. Nucleolar constrictions… Expand

Molecular systematics and biogeography of Resedaceae based on ITS and trnL-F sequences.
The Resedaceae, containing 6 genera and ca. 85 species, are widely distributed in the Old World, with a major center of species diversity in the Mediterranean basin. Phylogenetic analyses of ITS and… Expand

Cytotaxonomic studies in Brazilian Rhynchospora (Cyperaceae), a genus exhibiting holocentric chromosomes
The genus Rhynchospora (Cyperaceae) is a widely distributed Brazilian group, with approximately 150 species. We have studied mitosis and (or) meiosis of 16 species of four sections (Dichromena, Lon...

Karyotypic Changes through Dysploidy Persist Longer over Evolutionary Time than Polyploid Changes
Chromosome evolution has been demonstrated to have profound effects on diversification rates and speciation in angiosperms. While polyploidy has predated some major radiations in plants, it has also… Expand

Strait of Gibraltar: an effective gene-flow barrier for wind-pollinated Carex helodes (Cyperaceae) as revealed by DNA sequences, AFLP, and cytogenetic variation.
The Strait of Gibraltar is the most important barrier disconnecting the landmasses of Europe and Africa on the western Mediterranean extreme. Carex helodes is a wind-pollinated species endemic to the… Expand

Multiple Locations of the rDNA Sites in Holocentric Chromosomes of Rhynchospora (Cyperaceae)
Several cytogenetic studies have shown that representatives of the family Cyperaceae have holocentric chromosomes. Despite their interesting chromosome morphology, the chromosome organization has not… Expand

Agmatoploidy and Symploidy in Rhynchospora cephalotes (L.) Vahl (Cyperaceae)
In this paper we present the cytogenetic data of Rhynchospora cephalotes (L.) Vahl, in the section Cephalotae Kukenth. Chromosome numbers of R. cephalotes are assumed as 2n=17, 18 and 19. According… Expand
