  • Toxic effect of Ustilago scitaminea on sugarcane callus ...

    Ustilago scitaminea Sydow is the agent of the sugarcane smut. The changes induced by the fungus in the host development suggest alterations of the growth factor content in the plant (Byther and Steiner 1974; Pêros 1984). The use of in vitro leaf tissue culture systems to investigate the mechanisms occurring in sugarcane has certain advantages, since the callus growth and organogenesis depend ...

  • Studies on sugar-cane smut (Ustilago scitaminea) .

    Germination of chlamydospores of Ustilago scitaminea Sydow is typical of the Ustilaginaceae only on rich nutrient media such as potato dextrose agar. On sugar cane surfaces sporidia are rarely produced; the promycelia give rise directly to infection hyphae. This atypical germination sequence also takes place on non-nutrient media and on media containing only sugars (mannose, sucrose, lactose).
