Plant-fungi research. Collection of petri dish cultures of plants and the fungi associated with their roots. At top centre, the plants grow in a sterile growth chamber. At top right are selected spores that will germinate and form hyphae. The sequence of petri dishes from centre right, clockwise to upper left, show culturing of the fungus and plant, and (from lower centre) them being placed together. The final petri dish (upper left) shows a network of Glomus hyphae between the roots of a leek plant. This is an an example of mycorrhizal symbiosis. Photographed at the University of Pisa, Italy.
