Comparatively Barcoded Chromosomes of Brachypodium Perennials Tell the Story of Their Karyotype Structure and Evolution [PDF]

, 2019
The Brachypodium genus is an informative model system for studying grass karyotype organization. Previous studies of a limited number of species and reference chromosomes have not provided a comprehensive picture of the enigmatic phylogenetic ...

The genome of the vervet (Chlorocebus aethiops sabaeus) [PDF]

, 2015
Warren, Wesley C. et al.We describe a genome reference of the African green monkey or vervet (Chlorocebus aethiops). This member of the Old World monkey (OWM) superfamily is uniquely valuable for genetic investigations of simian immunodeficiency virus ...

Updating the list of chromosome numbers for Philodendron (Araceae)

Acta Botânica Brasílica
Aiming for a better understanding of karyotype evolution within Philodendron, we report chromosome counts for 23 species of the genus, of which 19 are being reported for the first time, thus increasing to 84 ( ca.

Biological Flora of Britain and Ireland: Geranium sylvaticum*

Journal of Ecology, Volume 114, Issue 2, February 2026.
Geranium sylvaticum is a perennial forb of upland grasslands, woodlands and riverbanks in northern Britain, with scattered native occurrences also in Wales, central England and Northern Ireland. It has an extensive native range in Europe and Asia. The species is gynodioecious, with individual plants typically female or hermaphrodite.

Review of chromosome cytology in Moraea (Iridaceae: Irideae): what chromosomes reveal about the evolution of the genus

Bothalia: African Biodiversity & Conservation, 2013
A review of the chromosome cytology of the African and Eurasian geophytic genus Moraea Mill. (currently 214 spp.); including 51 new counts, many for taxa poorly known cytologically or not counted before, that shows that 167 species, representing 78% of ...

Chromosomal Diversity as a Predictor of Lineage Diversification in Ants Across Phylogenetic and Geographic Gradients

Journal of Biogeography, Volume 53, Issue 1, January 2026.
ABSTRACT Aim To investigate macroevolutionary and biogeographic patterns of chromosome number variation in ants (Formicidae), and to test whether chromosomal diversity is taxonomically structured, associated with species richness, varies with latitude, and accumulates over evolutionary time. Location Global.

Morphological and genomic characterization of Rhynchospora tenuis complex (Cyperaceae) and its taxonomic implications

Rodriguésia
Species of Rhynchospora sect. Tenues are morphologically very similar. Rhynchospora tenuis complex is the most problematic species complex in this group and it concentrates entities of difficult delimitation, as is the case of R. tenuis, R. tenuis subsp.

Molecular phylogeny, genome sizes and chromosome numbers in melic grasses and its relatives (Pooideae, Poaceae) with a revised classification of the genus Melica

TAXON, Volume 74, Issue 6, Page 1421-1437, December 2025.
Abstract The genus Melica comprises around 90 species, which are widespread throughout the temperate and subtropical regions of the world. In contrast to numerous species complexes in the grass subfamily Pooideae, the genus Melica forms a very homogeneous group of mainly diploid species with a uniform basic chromosome number of x = 9.

Multivariate karyomorphometric analysis and taxonomic implications in Allium sect. Cupanioscordum (Amaryllidaceae) [PDF]

, 2015
Significant karyological variation occurs amongst different taxa/populations in the A. cupani group. The ancestral diploid chromosome complement is 2n = 16 (x = 8), but populations of A. cupani s.l. also exhibit dysploidy (2n = 14), polyploidy (2n = 4x =

Cytogeography of Gentianaceae-Exaceae in Africa, with a special focus onSebaea: the possible role of dysploidy and polyploidy in the evolution of the tribe [PDF]

Botanical Journal of the Linnean Society, 2008
Unlike other tribes of Gentianaceae, Exaceae have so far received little attention regarding their karyological evolution. Indeed, only 35 chromosome number counts (19 species) have been referenced to date, representing only a negligible fraction of the tribal diversity. In this paper, we performed an intensive chromosome count on material collected in
