(A) Left panel: All genes that are significantly changed compared to the wild type upon deletion of subunits of the Sir Complex and kinases of Ste11-mediated MAPK cascading pathway. Right panel: Genes marked by green bar are <10 kb from the nearest telomeres, and genes marked by red bar are involved in mating process. (B) A novel predicted regulatory network that SIR complex and (Ste11-mediated) MAPK cascades pathway has functional overlap through kinase Fus3 (that were down regulated in the SIR complex) in mating. Known Ste11-mediated MAPK pathway is shown by Solid lines. Solid lines: known interactions, dashed lines: newly predicted interactions. (C) Novel causal relationships and undirected interactions predicted by DM_BN among STFs: Cst6, Sfp1, Bas1, Mac1, Gsm1, Ixr1, Haa1, Ume6 and Cad1, and some subunits of the SIR, SWI/SNF and SAGA complex, under parameter setting . Purple nodes: chromatin machinery components; Green nodes: sequence-specific DNA binding transcription factors.
