GlcNAc induces hyphal genes, a subset of galactose-induced genes, and a set of novel genes. The growth conditions for the cells used in the microarray analyses of gene expression are indicated at the top of each column and explained in the legend to Fig. 1. (A) Analysis of the effects of GlcNAc on genes that have previously been reported to be induced when cells are treated with serum to form hyphae (12, 16). (B) GlcNAc induced a subset of galactose-induced genes. (C) A novel set of genes induced by GlcNAc, of which the orf19.1066 gene is induced to the highest levels and most consistently under all four conditions.
