Última Filamentous growth in Saccharomyces cerevisiae BJM Ceccato-Antonini,Sandra Regina; Sudbery,Peter Edwin. Fungal dimorphism is a complex phenomenon triggered by a large variety of environmental factors and consists of a reversible alternating pattern of growth between different elliptical and filamentous forms of cells. Understanding the mechanisms that regulate these events is of major interest because of their implications in fungal pathogenesis, cell differentiation and industry. Diploid cells of Saccharomyces cerevisiae transform from budding yeast to pseudohyphae when starved for nitrogen, giving the cells an advantage in food foraging, which is sensed by at least two signal transduction pathways: the MAP kinase (MAPK) and the PKA (cAMP-dependent protein kinase A) pathways. The output of these signalling pathways is the expression of pseudohypha-specific... Tipo: Info:eu-repo/semantics/article Palavras-chave: Filamentation; Saccharomyces cerevisiae; Pseudohyphae.

Yeasts can produce pseudohyphae and hyphal-like extensions under certain growth conditions like isoamyl alcohol (IAA) induction, a chief constituent of fusel oil, which is a subproduct from the ethanolic fermentation. The morphology switch from yeast to a filamentous form can be troublesome to the process. In this work it was studied the influence of fusel alcohols, nitrogen sources (ammonium sulphate and leucine) and glifosate (a chemical maturator for sugar cane) added to a complex medium on some industrial strains of yeasts isolated from the fermentative process. Two industrial strains showed transition to hyphal-like extensions or pseudohyphae (clusters of cells) upon addition of IAA from 0.3 to 0.9% /v. The alterations were reversible when the yeasts...
