Paleontologists find fossil relative of Ginkgo biloba

A discovery of well-preserved fossil plants by paleontologists from the United States, China, Japan, Russia and Mongolia has allowed researchers to identify a distant relative of the living plant Ginkgo biloba.

Gene that determines floral sex may be key to new hybrid seeds

A Yale University-led team of scientists has discovered a key gene in that controls the sex of maize flowers—a discovery that could open the door to creation of highly productive hybrid seed in many agricultural plants ...

Lemur extinctions 'orphaned' some Madagascar plant species

The extinction of several species of large lemurs in Madagascar has created isolated "orphaned" plant species that once depended upon the animals to eat and disperse their large seeds, a Yale-led survey has found.

Gene blocking lettuce germination also regulates flowering time

Like most annuals, lettuce plants live out their lives in quiet, three-act dramas that follow the seasons. Seed dormancy gives way to germination; the young plant emerges and grows; and finally in the climax of flowering, ...

Scientists discover how arsenic builds up in plant seeds

Researchers from FIU's Herbert Wertheim College of Medicine Barry P. Rosen and Jian Chen, both from the Department of Cellular Biology and Pharmacology, are part of an international team that has identified how arsenic gets ...

Actuators that mimic ice plants

Engineers developing moveable robot components may soon take advantage of a trick plants use. Researchers at the Max Planck Institute of Colloids and Interfaces in Potsdam and Harvard University in Cambridge (USA) have devised ...

Food-delivery process inside seeds revealed

Inside every seed is the embryo of a plant, and in most cases also a storage of food needed to power initial growth of the young seedling. A seed consists mainly of carbohydrates and these have to be is transported from the ...

How seeds recognise the seasons

Scientists at the University of York have played a key role in new research into the way 'mother' plants use their memory of the seasons to teach their seeds the most advantageous time to germinate.
