Figure 5.
Plasma membrane order of the parental and pdr18Δ strains growing in absence or presence of acetic acid, as reported by Laurdan Generalized Polarization (GP) values. (a) GP values from individual exponentially-growing cells of the parental and pdr18Δ strains cultivated either in the presence or absence of 60 mM acetic acid at pH 4.0. The boxplots represent the first and third quartiles and median for each cell population; (b) Examples of Laurdan Generalized Polarization images for the parental strain and pdr18Δ cells grown in absence or presence of acetic acid stress. Results arise from the analysis of at least 100 cells obtained from three independent assays. Asterisks represent statistical significant differences, based on t-student tests.
