The evolution of the seed represents a remarkable life‐history transition for photosynthetic
organisms. Here, we review the recent literature and historical understanding of how and …

Fundamental differences in the distribution of oceans and landmasses in the Northern and
Southern Hemispheres potentially impact patterns of biological diversity in the two areas …

Background Next-generation sequencing has provided a wealth of plastid genome
sequence data from an increasingly diverse set of green plants (Viridiplantae). Although …

Although they are relative latecomers on the evolutionary scene, having emerged only 135?
170 million years ago, angiosperms—or flowering plants—are the most diverse and species …

We present molecular dating analyses for land plants that incorporate 33 fossil calibrations,
permit rates of molecular evolution to be uncorrelated across the tree, and take into account …

Plants have utterly transformed the planet, but testing hypotheses of causality requires a
reliable time‐scale for plant evolution. While clock methods have been extensively …

Increasingly robust understanding of angiosperm phylogeny allows more secure
reconstruction of the flower in the most recent common ancestor of extant angiosperms and …

Molecular data on relationships within angiosperms confirm the view that their increasing
morphological diversity through the Cretaceous reflected their evolutionary radiation …

Phylogenetic definitions are provided for the names of 53 clades of vascular plants.
Emphasis has been placed on well‐supported clades that are widely known to non …

Background Ovules as developmental precursors of seeds are organs of central importance
in angiosperm flowers and can be traced back in evolution to the earliest seed plants …
