Structural and histochemical approach to the fruit and seed diversity of Cyperaceae in an evolutionary context.

The Cyperaceae fruit consistency depends on the mesocarp. Seed structure is diverse and related to the evolutionary history of their species. A new storage tissue is described for Cyperaceae.

Heterochrony and repurposing in the evolution of gymnosperm seed dispersal units.

Background: Plant dispersal units, or diaspores, allow the colonization of new environments expanding geographic range and promoting gene flow. Two broad categories of diaspores found in seed plants are dry and fleshy, associated with abiotic and biotic dispersal agents, respectively. Anatomy and developmental genetics of fleshy angiosperm fruits is advanced in contrast to the knowledge gap for analogous fleshy structures in gymnosperm diaspores.

Using integrative taxonomy and multispecies coalescent models for phylogeny reconstruction and species delimitation within the "Nastanthus-Gamocarpha" clade (Calyceraceae).

The Calyceraceae (47 spp.) is a small family of plants that is sister to the Asteraceae (∼ 25,000 spp.), one of the largest families of angiosperms.
