Recent advances in phylogeny reconstruction and floral genetics set the stage for new
investigations of the origin and diversification of the flower. We review the current state of …

Petals appear in many angiosperm taxa, yet when and how these attractive organs
originated remains unclear. Phylogenetic reconstructions based on morphological data …

The genetic basis and evolution of sex determination in dioecious plants is emerging as an
active area of research with exciting advances in genome sequencing and analysis …

The carpel is the female reproductive organ that encloses the ovules in the flowering plants
or angiosperms. The origin of the carpel and its subsequent morphological modifications …

Abstract The Early Cretaceous palynological successions record one of the earliest waves of
angiosperm radiation in several low-latitude localities, including the Arabian Plate. The …

The question of the origin of petals has long been debated in the botanical literature.
Ranunculales are characterized by a spectacular floral diversity, particularly at the perianth …

In angiosperms, dioecious clades tend to have fewer species than their nondioecious sister
clades. This departure from the expected equal species richness in the standard sister clade …

The question of whether any angiosperms existed before the Cretaceous period is of key
importance for understanding seedplant evolution. Most authorities suggest that the earliest …

An updated description of the pollination and reproductive biology of basal angiosperms is
given to show their principal associations with pollinating agents. The review considers …

Flower, enclosed ovule and tetrasporangiate anther are three major characters
distinguishing angiosperms from other seed plants. Morphologically, typical flowers are …
