  6. Inventory of Mlpsignalinggenes Selection ofsignalinggenesbased on litteraturewith a focus on plant/fungal interactions => large number of publications on transduction pathwaysinvolved in plant-pathogeninteractions (deletion mutants, role in virulence, mating, filamentation…) => extensive studies in Saccharomyces cerevisiae Since… Completeinventoryof signalinggenes in Neurospora crassa (Borkovichet al, 2004) Focus on transduction pathways in Magnaporthegriseagenomepaper (Dean et al, 2005) Comparative analyses of severalgenesfamilies in Aspergillisp (Lafon et al, FGB, 2006) Recentreview on fungalG-aproteinrelatedsignaling (Li et al, 2007; Ann RevMicrobiol ) U.

  12. Mlpsignalinggenesinventory - I Compilation of sequenceslisted in N. crassaand fungalsignalingreviews About 30 classes of proteinswereinvestigated => — histidine kinases, p21-activated kinases, germinal center kinases, oananichecAMPdependent-proteinkinase (PKA), protein kinase C (PKC), mitogen-activatedprotein kinases (MAPK, MAPKK, MAPKKK), — G-proteincoupledreceptors (GPCR: glucose sensor, cAMP, PTH11, PheR, Stm1, …), heterotrimeric ( su) and monomeric (ras) G-proteins, Regulator of G-proteins (RGS) — adenylatecyclase (AC), phosphodiesterase (PDE), phospholipase C (PLC) — protein phosphatases (PP1, PP2A-2B-2C, PP5) — Calcium-relatedsignalingproteins (Ca2+-ATPases, Calmoduline (CaM), Ca2+ and/or CaM-bindingprotein, Ca2+ exchanger, Ca2+ permeablechannel) A large catalog of MANUALLY VALIDATED or CURATED GENE MODELS wasestablished in L. bicolor and homologs (blastp/tblastn) werefound in C. cinereus, P. chrysosporium, U. maydis and C. neoformans
