Identifying discontinuous entities within species complexes is a major topic in systematic
and evolutionary biology. Comprehensive inventories describing and identifying species …

Background and Aims The Quadrifaria group of Paspalum (Poaceae, Paniceae) comprises
species native to the subtropical and temperate regions of South America. The purpose of …

• Premise of the study: Tropical regions have high species diversity, and polyploidization is a
major mechanism of speciation in plants. However, few cases of natural polyploidy have …

DNA content was estimated by flow cytometry in seventeen taxa from the Dilatata,
Quadrifaria and Paniculata groups of Paspalum and five synthetic hybrids. Results were …

The Dilatata group of Paspalum includes species and biotypes native to temperate South
America. Among them, five sexual allotetraploids (x= 10) share the same IIJJ genome …

Paspalum dilatatum Poir. and its related species are warm-season grasses native to the
grasslands of temperate South America. The group comprises several sexual tetraploid …

Paspalum notatum is a subtropical grass present throughout America, and one of the main
constituents of the natural grasslands in Uruguay. An apomictic autotetraploid (2n= 4x= 40) …

Paspalum, an American genus of the x= 10 Paniceae clade, includes about 330 species,
four subgenera, and 27 informal groups. Within the genus, the Quadrifaria and Virgata …

The condensation patterns (CPs) of prophase chromosomes represent poorly explored and
little understood karyotype features. Three distinct chromosome domains are observed in …

An important strategy to conduct intentional breeding of octoploid strawberry plants is to
recognize the functions of every chromosome. To do so, a methodology must be developed …
