Integration of gene expression, regulatory sequences, and environmental responsiveness. Schematics illustrating the hypotheses presented in this paper regarding the regulation of expression of genes that respond to (a) amino-acid and nitrogen source limitation and (b) different environmental stresses. Each circle in the Venn diagram represents a cluster of genes that is enriched for the known binding site of the indicated transcription factor or is known to be regulated by the indicated factor in response to the denoted conditions.
