Latest C4 carbon fixation Stories
Published evidence by SDSM&T and the New York State Museum suggests modern grasses eaten by large mammals of what is now the Mojave Desert are actually 15 million years old. Rapid
In examining the differences in photosynthetic activity among certain types of grasses, researchers from Brown University found that some plants are positioned to take evolutionary advantage of certain situations.
The evolution of plants and animals generally has been thought to occur through the passing of genes from parent to offspring and genetic modifications that happen along the way.
If you eat bread stuffing or grain-fed turkey this Thanksgiving, give thanks to the grasses — a family of plants that includes wheat, oats, corn and rice.
"I have a slide that has a photo of a cornfield and a big photovoltaic array," says Robert Blankenship, a scientist who studies photosynthesis at Washington University in St. Louis.
According to a popular hypothesis, grasses such as maize, sugar cane, millet and sorghum got their evolutionary start as a result of a steep drop in atmospheric carbon dioxide levels during the Oligocene epoch, more than 23 million years ago.
A new analysis of fossilized grass-pollen grains deposited on ancient European lake and sea bottoms 16-35 million years ago reveals that C4 grasses evolved earlier than previously thought.
Photosynthesis is arguably the most impressive feat of nature, where plants harvest light energy and convert it into the building blocks of life at fantastically high efficiency.
Around 30 to 40 million years ago, grasses on Earth underwent an epic evolutionary upheaval.
