Characterization of B-type cyclins in the smut fungus Ustilago maydis: roles in morphogenesis and pathogenicity.
Pathogenesis, morphogenesis and cell cycle are connected in the fungal pathogen Ustilago maydis. Here we report the characterization of the catalytic subunit of the cyclin-dependent kinase, encoded by the gene cdk1, and the two B-type cyclins present in this organism, encoded by the genes clb1 and clb2. These cyclins are not redundant and appears to be essential for cell cycle. The analysis of ...
متن کاملDiscrete developmental stages during teliospore formation in the corn smut fungus, Ustilago maydis.
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 tumors, hyphae give rise to teliospores, which are round, diploid cells surrounded by a specialized cell wall. Here we describe the time course of fungal development in the plant with a focus on the morphological changes in t...
متن کاملThe role of endocytosis for pathogenic development of the corn smut fungus Ustilago maydis
It has long been established that fungal growth and pathogenic development are supported by exocytosis. However, the role of endocytosis during these growth processes has not been elucidated yet. It was the aim of the present study to use the temperature-sensitive mutant of the endocytic t-SNARE Yup1, to analyse the importance of endocytosis for fungal growth and pathogenic development in Ustil...
متن کاملEndocytosis is essential for pathogenic development in the corn smut fungus Ustilago maydis.
It is well established that polarized exocytosis is essential for fungal virulence. By contrast, the contribution of endocytosis is unknown. We made use of a temperature-sensitive mutant in the endosomal target soluble N-ethylmaleimide-sensitive factor attachment protein receptor Yup1 and demonstrate that endocytosis in Ustilago maydis is essential for the initial steps of pathogenic developmen...
متن کاملHuitlacoche (corn smut), caused by the phytopathogenic fungus Ustilago maydis, as a functional food.
BACKGROUND In recent years the need has arisen to study and develop (or re-discover) foods that have nutritional characteristics as well as specific functions, such as improving health and/or reducing the risk of disease. For this reason knowledge of the nutritional value of food is important to promote greater consumer acceptance. In Mexico huitlacoche (also, cuitlacoche) has traditionally bee...
