Biology and histopathology of Ustilago filiformis (=U. longissima), a causal agent of leaf stripe smut of Glyceria multiflora

Abstract

Abstract:The aims of this study were to clarify the reproductive biology of the Ustilago filiformis Schrank, as causal agent of the stripe smut of Glyceria multiflora, determine the infection process of the pathogen and analyze the histological changes associated hostGlyceria any fungus attack. Moreover, the life cycle of the fungus was elucidated for the first time. Both teliospores and basidiospores were found to be equally efficient in producing the infection in Glyceria plants after the plants had been inoculated. These results constitute an important contribution for the understanding of the epidemiology of the disease.

“…In our samples, Cryptococcus appeared evenly distributed throughout the year, except for the summer, when its RA was about 10 times lower than in the other seasons ( Figure S6 ). In addition to the potentially pathogenic fungal genera listed in the ABSA database, we identified other Fungi genera that are reportedly potential pathogens, according to previous studies, e.g., the Ascomycota Candida [ 13 , 24 ] and Colletotrichum [ 50 ], and the Basidiomycota Ustilago [ 51 ]. The genus Colletotrichum is ranked as the eighth most devastating plant-pathogenic fungus in the world; it consists of many species causing plant disease on a wide range of plants, covering both woody and herbaceous plants.…”

“…The Ustilago genus is represented by more than 400 cosmopolitan species, which are parasitic and infect the floral parts of wheat, barley, oat, maize, sugarcane, and wild grasses. The geographical distribution of the Ustilago disease involves temperate areas of the world such as North India, Siberia, Europe, and North and South America [ 51 ].…”
