Fig. 4From: Metabolic differentiation of surface and invasive cells of yeast colony biofilms revealed by gene expression profilingFunctional gene groups, upregulated in aerial and in root cells. Following manual annotation, coding genes that were upregulated (at least two-fold and with a p-value <0.05) in root or in aerial cells were clustered according to functional group and the percentages of upregulated genes in each group were calculatedBack to article page
