摘要: Genome-wide transcript profiling was used to monitor signal transduction during yeast pheromone response. Genetic manipulations allowed analysis of changes in gene expression underlying signaling, cell cycle control, and polarized morphogenesis. A two-dimensional hierarchical clustered matrix, covering 383 the most highly regulated genes, constructed from 46 diverse experimental conditions. Diagnostic subsets coexpressed genes reflected signaling activity, cross talk, overlap multiple mitogen-activated protein kinase (MAPK) pathways. Analysis profiles specified by two different MAPKs-Fus3p Kss1p-revealed functional filamentous growth mating responses. Global reflects biological responses associated with activation perturbation
