A new species of Gomesa (Oncidiinae, Orchidaceae) from inselbergs in Brazilian caatinga: morphological and karyological evidence.
We describe a new species of Gomesa (Oncidiinae, Orchidaceae), Gomesa caatingana, with restricted distribution on caatinga inselbergs in Paraíba and Pernambuco States, Brazil. Morphological and karyological characters of the new species were compared with those of Gomesa flexuosa, which is morphologically the most closely related species. Differences in geographical distribution,... -

Extensive plastid-nuclear discordance in a recent radiation of Nicotiana section Suaveolentes (Solanaceae)
Nicotiana section Suaveolentes is the largest section of Nicotiana and is a monophyletic group of allotetraploid species. Most of the species are endemic to Australia, but three species occur on islands in the South Pacific as far east as French Polynesia and one species is native to Namibia. Here, we... -

The correlation of phylogenetics, elevation and ploidy on the incidence of apomixis in Asteraceae in the European Alps.
Asexual reproduction has often been regarded as an evolutionary dead end, but asexual lineages (most notably those that are apomictic) are present in several angiosperm families and often comprise a large number of taxa, both widespread and endemic. Investigating correlations between genetic, environmental and taxonomic factors and the incidence of... -

Chromosome numbers and heterochromatin variation in introgressed and non-introgressed populations of Epidendrum (Orchidaceae: Epidendroideae): interspecific transfers of heterochromatin lead to divergent variable karyotypes in the parental populations.
Some groups in Epidendrum have stable chromosome numbers, whereas the species of Epidendrum subgenus Amphiglottium exhibit high levels of chromosome number variability and other genomic alterations. Polyploidy and dysploidy have both been invoked to explain chromosome number variation in the subgenus, but little is known about what is driving the...Nollet, Felipe ; Medeiros Neto, Enoque ; Cordeiro, Joel M P ; Buril, Maria Teresa ; Chase, Mark W …

Evolutionary dynamics of transposable elements and satellite DNAs in polyploid Spartina species
Repeated sequences and polyploidy play a central role in plant genome dynamics. Here, we analyze the evolutionary dynamics of repeats in tetraploid and hexaploid Spartina species that diverged during the last 10 million years within the Chloridoideae, one of the poorest investigated grass lineages. From high-throughput genome sequencing, we annotated...Giraud, Delphine ; Lima, Oscar ; Huteau, Virginie ; Coriton, Olivier ; Boutte, Julien …

Giant Fern Genomes Show Complex Evolution Patterns: A Comparative Analysis in Two Species of Tmesipteris (Psilotaceae).
Giant genomes are rare across the plant kingdom and their study has focused almost exclusively on angiosperms and gymnosperms. The scarce genetic data that are available for ferns, however, indicate differences in their genome organization and a lower dynamism compared to other plant groups. Tmesipteris is a small genus of... -

Genetic variation in Loudetia simplex supports the presence of ancient grasslands in Madagascar.
Reconnaître que les prairies dominées par Loudetia étaient répandues avant la colonisation humaine souligne que les écosystèmes ouverts étaient et continuent d'être un composant important de la biodiversité de Madagascar. Il est urgent de réaliser des inventaires de la biodiversité et une taxonomie intégrée pour le traitement de la... -
