Teleomorph formation of Setosphaeria monoceras, a perfect state of Exserohilum monoceras, by Japanese isolates

Abstract

Setosphaeria monoceras, a teleomorph of Exserohilum monoceras, has been produced in culture through the crossing of compatible mating-type isolates from Japan. In this study, Sachs’ agar medium + maize leaf were placed at a constant temperature of 25°C with 16 h light and 8 h dark cycles for 25–30 days. When assessed, the morphological characteristics were almost identical to those of original description by Alcorn, using Australian isolates. This note presents the second report investigating the development of the perfect stage of E. monoceras.
