Transcriptomic analyses of 20 plant species helped identify genes involved in the evolution of seed production, offering ...

Insect pollination is a decisive process for the survival and evolution of angiosperm (flowering) plants and, to a lesser extent, gymnosperms (without visible flower or fruit). There is a growing ...

After decades of molecular phylogenetic studies, the deep phylogeny of gymnosperms has not been resolved, and the phylogenetic placement of Gnetales remains one of the most controversial issues in ...

EVEN in these days of specialisation, no real botanist dismisses the Gymnosperms from his field of study. They still possess an inherent interest, although for a hundred years they have been classic ...

The origin of flowering plants, or angiosperms, stands as one of evolutionary biology's great enigmas. Scientists know that they diverged from the seed-bearing plants, or gymnosperms, at least 150 ...

For many years, Charles Darwin was haunted by flowers. In 1859, the naturalist published his most famous work, On the Origin of Species, the book that is generally regarded as the foundation of ...

The discovery of a beetle and pollen in 105-million-year-old Spanish amber is proof of a new insect pollination mode that dates to the mid-Mesozoic, before the rise of flowering plants. The study ...

The world as we know it today is almost inconceivable without the rich and colourful landscapes created by plant life. Among them are flowering plants, or angiosperms, which are by far the most ...

Named for Charles Darwin, the only known specimen of a newly discovered beetle, Darwinylus marcosi, died in a sticky gob of tree sap some 105 million years ago in what is now northern Spain. As it ...

Robert Brown (1827) recognized the distinction between the two major classes of seed plants on the basis, respectively, of exposed ovules, which receive pollen directly, and enclosed ovules, which do ...
