Abstract:Saccharomyces cerevisiae produces a multicellular phenotype, known as a
mat, on a semi-solid medium. This biofilm phenotype was first described
in the lab strain 1278b and has been analyzed mostly in this same
background. Yeast cells form a mat by spreading across the medium and
adhering to each other and the surface, in part through the variegated
expression of the cell adhesin, FLO11. This process creates a
characteristic floral pattern and generates pH and glucose gradients
outward from the center of the m… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
