Mating and infection structures of Ustilago maydis produced in culture and on maize plants
were examined with light and electron microscopy. Fusion tubes formed between low …

Smut diseases are caused by Basidiomycetes of the order Ustilaginales. Their occurrence is
worldwide and cereals and grasses serve as most common hosts. Among the estimated …

MATERIALS AND METHODS Seeds of Golden Cross Bantam Hybrid sweet corn, a variety
highly susceptible to U. maydis, were surface-sterilized in 5% sodium hypochlorite for 5 min …

Ustilago maydis is a dimorphic fungus with a yeast-like non-pathogenic form and a
filamentous (hyphal) pathogenic form that induces tumor formation in maize. Within mature …

The main types of symptom produced when 7 to 10-day old seedlings of maize were
artificially inoculated with sporidia of the maize smut fungus, Ustilago maydis, were chlorotic …
