Global expression analysis shows distinct expression patterns of metabolic processes, signal pathways, transcription factors and secreted proteins during microsclerotia formation. A. to D. Expression trends of genes encoding proteins in four functional categories. A. The central metabolic pathways include the glyoxylate cycle, glycolysis/glucogeogenesis, TCA cycle, pentose phosphate pathway, fatty acid oxidation; B. Signal transduction and components, such as MAPK cascades, RGSs (regulators of G protein signaling), GPCR (G protein coupled receptors) and calcium signaling. C. Four main classes of transcription factors, i.e. C2H2, bHLH, bZIP and Zn2Cys6. D. Putative secreted proteins and ABC transporter genes. y axes are log2-transformed total intensities. The total numbers within a gene family are shown in numerals and the numbers of expressed genes within a family are shown in parentheses.
