Karyotypic analyses and genomic affinity among Argentinean species of Passiflora [PDF]
The genus Passiflora (Passifloraceae) has more than 500 species, nineteen are native to Argentina. By their austral distribution, these species were included in breeding programs to obtain ornamental varieties tolerant to low temperatures.

On the way to diploidization and unexpected ploidy in the grass Sporobolus section Spartina mesopolyploids [PDF]
Plant history is characterized by cyclical whole genome duplication and diploidization with important biological and ecological consequences. Here, we explore the genome history of two related iconic polyploid grasses (Sporobolus alterniflorus and S ...

Does the evolution of micromorphology accompany chromosomal changes on dysploid and polyploid levels in the Barnardia japonica complex (Hyacinthaceae)? [PDF]
Background Chromosome number and genome size changes via dysploidy and polyploidy accompany plant diversification and speciation. Such changes often impact also morphological characters.

Recurrent polyploidy and descending dysploidy as plant genome shapers: Insights from Sporobolus (Chloridoideae, Poaceae) genomes. [PDF]
Polyploidization or whole genome duplication (WGD) is a source of genetic and phenotypic novelties and is a widespread mechanism of speciation across plant lineages. It is often followed by complex genome dynamics, including diploidization.

Chromosomal Evolution and Apomixis in the Cruciferous Tribe Boechereae [PDF]
The mustard family (Brassicaceae) comprises several dozen monophyletic clades usually ranked as tribes. The tribe Boechereae plays a prominent role in plant research due to the incidence of apomixis and its close relationship to Arabidopsis.
