A defining feature of angiosperms is double fertilization involving the female gametophyte central cell and formation of a nutrient-storing tissue called endosperm. The route for the evolutionary ...
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 ...
Plant-insect interactions, one of the critical bedrocks for modern ecosystems, are largely dominated by insect-angiosperm relationships owing to the hegemony enjoyed by flowering plants since the Late ...
This is a preview. Log in through your library . Abstract Using a compartmentalization approach, we conducted phylogenetic analyses of the basalmost extant angiosperms using sequences from six genes ...
Trees are typically organized into two categories: hardwoods (angiosperms) and softwoods (gymnosperms). A new study suggests that there is a third type of wood—known as “midwood”—that could explain ...
ARGUABLY the world’s weirdest plant, Welwitschia mirabilis is a tangled mass of shredded, fraying leaves in the Namib desert. For a thousand years, perhaps more, it grows just two long leaves, which ...
Flowering plants may have evolved 250 million years ago, more than 100 million years earlier than the oldest fossilised flowers so far found. Today, flowering plants – known as angiosperms – are the ...
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 ...
