Chromosome number, heterochromatin, and genome size support recent polyploid origin of the Epidendrum nocturnum group and reveal a new species (Laeliinae, Orchidaceae).
The Epidendrum nocturnum Jacq. group comprises about 60 species. Nine species occur in Brazil, predominantly in the Atlantic and Amazon Forests. The group is taxonomically complex because its species are morphologically similar and not easily distinguished. The main objective of this work is to characterize their chromosome evolution and how... -

Correlated evolution of seed mass and genome size varies among life forms in flowering plants.
Seeds show important variation as plant regenerative units among species, but their evolutionary co-variations with other plant characteristics are still poorly understood. Whilst a positive association of seed mass with genome size (GS) and life forms has already been documented, a broad-scale quantification of their evolutionary correlation and adaptive selection... -
