Recent advances in molecular phylogenetics and a series of important palaeobotanical discoveries have revolutionized our understanding of angiosperm diversification. Yet, the origin and early ...

Angiosperms (flowering plants) are the most diverse of all major lineages of land plants and the dominant autotrophs in most terrestrial ecosystems. Their evolutionary and ecological appearance is ...

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 ...

Aluminum phytotoxicity and genetically based aluminum resistance has been studied intensively during recent decades because aluminum toxicity is often the primary factor limiting crop productivity on ...

Paleontologists may be on the verge of solving one of the great mysteries in the history of life on our planet – the origin of angiosperms, the flowering plants. The importance of angiosperms cannot ...

This is a preview. Log in through your library . Abstract Examination of literature shows that a number of authors regard outbreeding and heterozygosity as the prevalent factors associated with ...

Large parts of today’s food production are derived from different plant species, but premature abscission may result in reduced yield. Abscission is when plant organs are detached from the mother ...

Angiosperms produce flowers and fruits, which contain their seeds. Scientists think they have the answer to a puzzle that baffled even Charles Darwin: How flowers evolved and spread to become the ...

Fossils of angiosperms first appear in the fossil record about 140 million years ago. Based on the material in which these fossils are deposited, early angiosperms must have been weedy, fast-growing ...

They are very tiny, but they are a key source of information when it comes to Earth's evolutionary history: pollen grains are usually no larger than 20 micrometers, or 0.02 millimeters. Using these ...

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 ...
