• Background Understanding the mode and mechanisms of the evolution of the angiosperm flower is a long-standing and central problem of evolutionary biology and botany. It has essentially remained ...

Most of our food is from angiosperms, while more than 90% of angiosperms require insect pollination - making this pollination method hugely important. Nevertheless, scientists have long been unclear ...

Angiosperm evolution involves a major transition from spiral to whorled arrangements of floral organs. Examination of the genetic programs specifying floral organ identity in Nigella damascene, a ...

A tiny flower pressed between layers of sandstone for more than 160 million years could be the oldest flower fossil ever found, a new study reports. However, not everyone agrees that the fossil ...

From southern Africa's pineapple lily to Western Australia's swamp bottlebrush, flowering plants are everywhere. Also called angiosperms, they make up 90 percent of all land-based, plant life. New ...

• 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. Angiosperm ovules are ...

We now know what the ancestor of today’s flowers looked like, thanks to scientists who used computer models to re-create the plant that lived 140 million years ago. Before now, we didn’t understand ...

Scientists have reconstructed the appearance of the first flower, which has at least 10 gently curving and well-spaced petals. Flowering plants make up about 90% of the plants on earth. Their common ...
