Results of the study, titled "Dosage Sensitivity Shapes Balanced Expression and Gene Longevity of Homoeologs after Whole-Genome Duplications in Angiosperms," were published in The Plant Cell.

There are two main types of plants: flowering plants, known as angiosperms, and non-flowering plants, known as gymnosperms. The flower bud and fruit in the fossil are both clear indicators that F ...

Leaf economic traits from fossils support a weedy habit for early angiosperms. American Journal of Botany, 2010; 97 (3): 438 DOI: 10.3732/ajb.0900290 ...

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

This contrasts starkly with the evolutionary tree of dinosaurs. “Non-avian dinosaurs lost so many species, they lost entire lineages, which we don’t see in angiosperms,” Dr. Thompson said.

The surviving angiosperms got a boost from changes to the soil. The impact pulverized a great deal of rock and spread the mineral-rich dust all over the planet, including iron that enriched the soil.

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 ...

An estimated 362,000 species of angiosperms inhabit Earth, making up about 90 percent of our plant life. What is left is likely a gymnosperm which has a naked seed and is often a soft wood, such ...

Then, about 125 million years ago, angiosperms and their flowers sprang forth during the Cretaceous period, as fully formed as Aphrodite. Within 30 million years, angiosperms would dominate the Earth.

The secret to angiosperms’ success, they say, is a rapid downsizing of the plants’ cells beginning about 140 million years ago. This downsizing dramatically increased their efficiency.

Starting with flowering plants, the team designed molecular probes to search for 353 specific genes that can be found in the nuclei of all angiosperms. “The nuclear genome is humongous,” says ...
