ScienceDaily (May 15, 2012) — Prehistoric 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 colonised 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 the evolution of Earth's ecosystems.

The research highlights the importance of mutually beneficial plant-fungal relationships prior to the evolution of roots, whereby plants gain growth-promoting soil phosphorus from the fungi in exchange for sugars fixed by the plant through photosynthesis.

"I love science and it pains me to think that so many are terrified of the subject or feel that choosing science means you cannot also choose compassion, or the arts, or be awe by nature. Science is not meant to cure us of mystery, but to reinvent and revigorate it." by Robert M. Sapolsky
