Background Polyploidization promotes species formation and is widespread in
angiosperms. Genome changes dramatically bring opportunities and challenges to plants …

Lippia alba is a phenotypically variable tropical shrub thought to comprise a young
autopolyploid complex. Chromosome numbers in L. alba include 2 n= 30, 38, 45, 60, and …

Spice crops comprise diverse, economically valuable crops with numerous applications
ranging from culinary to pharmaceutical industries. Spices are an integral part of cuisines …

Triploidy is relatively common in Curcuma, especially among vegetatively propagated
species in cultivation. The aim of this study was to investigate the extent of triploidy and the …

Background Polyploidization can activate specific transposable elements, leading to their
accumulation. At the same time, the preferential loss of repetitive elements in polyploids may …

To study the origin and evolution of naturally occurring polyploids, we performed
phylogenetic analyses of nuclear ribosomal DNA spacers combined with molecular …

Wild Helianthus species are a valuable genetic resource for the improvement of cultivated
sunflower. We report the discovery and characterization of a unique high frequency …

Genetic affiliation, nuclear DNA content, and gamete functioning were examined in small
salt marsh Fucus from three localities in western Ireland. Individuals with small and …

Paspalum schesslii, a new species from the state of Mato Grosso in central-western Brazil, is
described and illustrated. The new species is related to P. malmeanum, from central-western …

A common view is that an accidental increase in ploidy contributes to the evolution of
neoplastic cells primarily by decreasing the fidelity of mitosis with extra chromosomes and …
