Ancient plants grown in state-of-the-art growth chambers recreating environmental conditions from more than 400 million years ago have shown scientists from the University of Sheffield how soil dwelling fungi played a crucial role in the evolution of plants. This ground breaking work provides fundamental knowledge of how plants colonized the land before roots evolved and the co-evolution of one of the most ancient relationships, between fungi and early plants that played a founding role in...

Controlling water loss is an important ability for modern land plants as it helps them thrive in changing environments. New research from the University of Bristol, published today in the journal Current Biology, shows that water conserving innovations occurred very early in plants' evolutionary history. The research focused on the role of stomata, microscopic pores in the surface of leaves that allow carbon dioxide gas to be taken up for use in photosynthesis, while at the same time allowing...

Innovative research technique reveals C4 grasses older than previously thought 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. This new evidence casts doubt on the widely-held belief that the rise of this incredibly productive group of plants was driven by a large drop in atmospheric carbon dioxide concentrations during the Oligocene epoch. The...

The world is a cooler, wetter place because of flowering plants, according to new climate simulation results published in the journal Proceedings of the Royal Society B. The effect is especially pronounced in the Amazon basin, where replacing flowering plants with non"“flowering varieties would result in an 80 percent decrease in the area covered by ever"“wet rainforest. The simulations demonstrate the importance of flowering"“plant physiology to climate regulation in...

By McElwain, Jennifer PALEOBIOLOGY Plants as a Force of Nature THE EMERALD PLANET: How Plants Changed Earth's History. David Beerling. xvi + 288 pp. Oxford University Press, 2007. $30. Plants, according to paleoclimatologist David Beerling, have shaped the atmosphere (and thus the climate) of the Earth to an amazing extent. In The Emerald Planet, Beerling guides readers through geological time from the earliest record of life through the greening of the planet to the present day, describing...
