High CO2 levels cause plants to thicken their leaves

Plant scientists have observed that when levels of carbon dioxide in the atmosphere rise, most plants do something unusual: They thicken their leaves. And since...

Taller plants moving into Arctic because of climate change

Plants in the Arctic are growing taller because of climate change, according to new research from a global scientific collaboration led by the University...

Burst of morning gene activity tells plants when to flower

For angiosperms -- or flowering plants -- one of the most important decisions facing them each year is when to flower. It is no...

Mechanism behind orchid beauty revealed

Researchers at Tohoku University in Japan have identified the gene related to the greenish flower mutation in the Habenaria orchid. Associate Professor Akira Kanno and...

New grass species makes a strong case for conservation

Originally collected 28 years ago in Ecuador, new species Poa laegaardiana has been just described, only to find out its prospects for surviving in its type...

Blue gene regulation helps plants respond properly to light

Researchers at the RIKEN Center for Sustainable Resource Science (CSRS) have discovered a process through which gene expression in plants is regulated by light....

Seeking new relationships with invasive species

With summer nearly here in North America, we often hear about invasive plants popping up in undesirable locations, "colonizing" different areas. But what if...

New technology has bright prospects for understanding plant biodiversity

Biologists get a new look at plant biodiversity and function with new imaging technology developed at the University of Alberta. "Biodiversity and ecosystem function are...

Camouflaged plants use the same tricks as animals

Plants use many of the same methods as animals to camouflage themselves, a new study shows. Research on plant camouflage is limited compared to the...

Study promotes cooperative weed management to curb herbicide resistance

In the fight against herbicide resistance, farmers are working with a shrinking toolkit. Waterhemp, a weedy nemesis of corn and soybean farmers, has developed...

How plants help offspring by passing on seasonal clues

New research carried out by the John Innes Centre has delved into the genetic memory systems through which plants pass seasonal information down to...

Explaining the history of Australia’s vegetation

University of Adelaide-led research has uncovered the history of when and why the native vegetation that today dominates much of Australia first expanded across...

How the waterwheel plant snaps

The midrib of the leaf (which has been transformed into a snap trap) bends slightly downwards in a flash, the trap halves fold in,...

Plants play greater role than herbivore extinctions in changes to ecosystem

Plants may have exerted greater influence on our terrestrial ecosystems than the megaherbivores that used to roam our landscapes, according to new research. Previously, scientists...

Droughts mean fewer flowers for bees

Bees could be at risk from climate change because more frequent droughts could cause plants to produce fewer flowers, new research shows. Droughts are expected...
