The internal transcribed spacers (ITS) of the nuclear ribosomal 18S–5.8 S–26S cistron
continue to be the most popular non-plastid region for species-level phylogenetic studies of …

Chromosome number is the karyotype feature most commonly used in cytotaxonomical
analyses. The chromosome number can be a plesiomorphic characteristic of a large clade …

Background 45S rDNA sites are the most widely documented chromosomal regions in
eukaryotes. The analysis of the distribution of these sites along the chromosome in several …

Common bean is grown and consumed principally in developing countries in Latin America,
Africa, and Asia. It is largely a subsistence crop eaten by its producers and, hence, is …

Together with the knowledge of the population structure, a critical aspect for the planning of
association and/or population genomics studies is the level of linkage disequilibrium (LD) …

Detailed comparative karyotype analyses have proved to be an important tool for taxonomy
and for understanding chromosome evolution. The basic principle of cytotaxonomy is that …

Karyotypic change constitutes an important evolutionary mechanism contributing to in
angiosperm diversification and speciation. Comparative analyses of the karyotype usually …

Although both are salient features of genomes, at first glance ribosomal DNAs and
transposable elements are genetic elements with not much in common: whereas ribosomal …

Recombination (R) rate and linkage disequilibrium (LD) analyses are the basis for plant
breeding. These vary by breeding system, by generation of inbreeding or outcrossing and by …

We examined chromosomal distribution of major ribosomal DNAs (rDNAs), clustered in the
nucleolar organizer regions (NORs), in 18 species of moths and butterflies using …
