The origin and diversification of angiosperms [PDF]

American Journal of Botany, 2004
The angiosperms, one of five groups of extant seed plants, are the largest group of land plants. Despite their relatively recent origin, this clade is extremely diverse morphologically and ecologically. However, angiosperms are clearly united by several synapomorphies.

Archaefructus – angiosperm precursor or specialized early angiosperm?

Trends in Plant Science, 2003
With molecular analyses indicating that angiosperms are not closely related to any other extant seed plant group, information from fossils might provide the only basis for reconstructing their origin. Therefore the description of a new Early Cretaceous angiosperm, Archaefructus, placed as the sister of all extant angiosperms, has created much debate ...

Polyploidy and angiosperm diversification

American Journal of Botany, 2009
Polyploidy has long been recognized as a major force in angiosperm evolution. Recent genomic investigations not only indicate that polyploidy is ubiquitous among angiosperms, but also suggest several ancient genome‐doubling events. These include ancient whole genome duplication (WGD) events in basal angiosperm lineages, as well as a proposed ...

Eocene Angiosperm Flowers

Science, 1974
Collections of well-preserved angiosperm flowers from the Middle Eocene of southeastern North America include a variety of morphological types. The first of these specimens to be studied extensively, a catkin, has yielded a great deal of structural information. Floral morphology, pollen morphology, and the nature of the peltate scales suggest that this

MAJOR CLADES OF THE ANGIOSPERMS

Cladistics, 1985
Abstract— Our knowledge of fundamental angiosperm interrelationships is still very incomplete. The absence of a narrowly circumscribed gymnosperm outgroup, ideally the sister group, makes character evaluation, necessary for a cladistic analysis, difficult.

The ecophysiology of early angiosperms

Plant, Cell & Environment, 2007
ABSTRACTAngiosperms first appeared during the Early Cretaceous, and within 30 million years they reigned over many floras worldwide. Associated with this rise to prominence, angiosperms produced a spectrum of reproductive and vegetative innovations, which produced a cascade of ecological consequences that altered the ecology and biogeochemistry of the ...
