Microbiology: Life on leaves

Johan Leveau1

Top

The surface of plant leaves — the phyllosphere — is home to many microbes. A 'community proteogenomics' approach offers a fresh look at what it takes to survive and thrive in this unique habitat.

Under the microscope, aerial plant leaves resemble eerie landscapes, with deep gorges, tall peaks and gaping pits that riddle the waxy surface. Add to this scenery a climate that features temperature highs of 50 °C or more, exposure to harmful ultraviolet rays, erratic periods of drought and limited access to nutrients, and one gets the picture that this is a hostile environment.
