▪ Abstract The first flowering plant fossils occur as rare, undiverse pollen grains in the Early
Cretaceous (Valanginian-Hauterivian). Angiosperms diversified slowly during the Barremian …

▪ Abstract In this review, we address the phylogenetic and structural relationships between
light-responsive promoter regions from a range of plant genes, that could explain both their …

Genetic mapping of wheat, maize, and rice and other grass species with common DNA
probes has revealed remarkable conservation of gene content and gene order over the 60 …

The specification of floral organ identity in the higher dicots depends on the function of a
limited set of homeotic genes, many of them members of the MADS-box gene family. Two …

Pollinating insects played a decisive role in the origin and early evolution of the
angiosperms. Pollinating orthorrhaphous Brachycera fossils (short-horned flies) collected …

Abstract 18S ribosomal RNA genes are the most widely used nuclear sequences for
phylogeny reconstruction at higher taxonomic levels in plants. However, due to a …

Advances in elucidating the molecular processes controlling flower initiation and
development have provided unique opportunities to investigate the developmental genetics …

Gynoecium and ovule structure was compared in representatives of all families of the
paleoherbs, including Nymphaeales (Cabombaceae, Nymphaeaceae), Piperales …

Ecological studies of hummingbird communities have emphasized the importance of local
conditions and contemporary interactions in the development of these varied faunas. A time …

Abstract The osmoprotectant 3-dimethylsulfoniopropionate (DMSP) occurs in Gramineae
and Compositae, but its synthesis has been studied only in the latter. The DMSP synthesis …
