Further Experiments on the Control of Barley Smuts

In 1930 the writer (7Y presented the results of early experiments on the control of barley covered smut (Ustilago hordei (Pers.) Kell, and Sw.) with dust fungicides, together with a rather comprehensive review of the pertinent literature on the subject up to that time. The development since then of new fungicidal dusts, some of which were effective in controlling barley stripe (Helminthosporium...

Stripe smuts of grasses: one lineage or high levels of polyphyly?

Stripe smut of grasses, Ustilago striiformis s.l., is a complex of smut fungi widely distributed over temperate and subtropical regions. The disease results in the shredding and death of leaf tissue following the rupture of elongated sori. Nearly 100 different grass species in more than 30 genera are infected by stripe smut. During the last two centuries more than 30 smut taxa have been describ...

Correction: Interspecific Sex in Grass Smuts and the Genetic Diversity of Their Pheromone-Receptor System

The grass smuts comprise a speciose group of biotrophic plant parasites, so-called Ustilaginaceae, which are specifically adapted to hosts of sweet grasses, the Poaceae family. Mating takes a central role in their life cycle, as it initiates parasitism by a morphological and physiological transition from saprobic yeast cells to pathogenic filaments. As in other fungi, sexual identity is determi...
