Banana Roots (IMAGE) Max Planck Institute for Chemical Ecology Caption This is the root of the susceptible banana variety Grande Naine (above) and the resistant banana Yangambi km5 (below): visible are the few red, phenylphenalenone containing regions on the resistant Yangambi km5 root within the predominantly healthy, pale root tissue. The root of the susceptible Grande Naine banana is covered in widespread dark, red-brown areas. This massive root damage in the Grande Naine banana will eventually cause the plant's death.
