However, this only occurs in brown or black circles and does not spread all over the plant. The first symptom of infection is dark, sunken areas that are soft and water soaked (Fig. In macrocyclic and demicyclic life cycles, the rust may be either host alternating (heteroecious) (i.e., the aecial state is on one kind of plant but the telial state on a different and unrelated plant), or non-host alternating (autoecious) (i.e., the aecial and telial states on the same plant host).
