Investigating Acid Stress Response in Different Saccharomyces Strains

Figure 2

Dendrogram of the fatty acid composition of yeast cytoplasmic membranes. Data were analysed by the standardized Euclidian distance, and the calculated matrix distance was used for clustering analysis by the UPGMA method. The composition and levels of fatty acids in the cell membrane were modulated in response to acid stress, particularly in the W303 strain, and this effect was prevented by addition of 86 mM of NaCl as shown by the dendrogram.
