Figure 1 - Plant gnotobiology: Epiphytic microbes and sustainable agriculture

Scheme illustrating the key experiment of J.-B. Boussingault of 1838, performed with pea (Pisum sativum) plants that were raised in sterile sand (A). O D sand without mineral salts; KP D sand with potassium and phosphate; KPS D sand with potassium, phosphate and nitrate. The root system of a pea plant (B) is characterized by numerous nodules that contain nitrogen-fixing bacteria (adapted from ref. 9).
