“…The number of VAGs in Foc1 and Foc4 is comparable to that in the Foc race 4 strain II5 (357) and other sequenced fungi (Table S4 & Table S5 in File S1). The search of the PHI database yielded 16 already characterized VAGs from Fo, including ARG1 [8], CHS2 [9], CHSV [10], CHS7 [9], FMK1 [11], FGA1 [12], FGA2 [13], FGB1 [14], FOW1 [15], FOW2 [16], foSNF1 [17], FRP1 [18], GAS1 [19], PacC [20] and SIX1 [21], indicating conservation in VAGs and pathogenesis among the different formae speciales of Fo. A number of Foc orthologs were found in the cereal pathogenic fungi F. graminearum (13 genes), Magnaporthe oryzae (88) and Ustilago maydis (31).…”

“…Also, GprD in Aspergillus fumigatus was suggested as an essential regulator of colony growth, hyphal morphogenesis, and virulence [95]. In Fo, the roles of GPCRs in G protein signaling pathway were not characterized, but G protein alpha and beta subunit were elucidated to be involved in growth, development and pathogenicity (FGA1 [12], FGA2 [13], FGB1 [14]). We revealed ∼115 genes encoding the putative GPCRs (including Pth11 like) and G proteins in Foc (Table S9 in File S1).…”

“…Two G α subunits from F. oxysporum , FGA1 and FGA2 , and the G β subunit from F. oxysporum , FGB1 , and G. moniliformis , GBB1 , have been functionally characterized (Delgado-Jarana et al , 2005; Jain et al , 2002, 2003, 2005; Sagaram & Shim, 2007). However, they do not have direct parallels in Gibberella ( Fusarium ) species.…”

“…For instance, G β subunits in Fusarium oxysporum and Gibberella moniliformis differ only in one amino acid, even though their functional roles in plant pathogenesis are quite different. Jain et al (2003) showed that F. oxysporum FGB1 , a gene encoding a G β subunit, is involved in virulence, while G. moniliformis GBB1 has no impact on maize stalk rot pathogenesis (Sagaram & Shim, 2007). The availability of three Fusarium genomes enables comparative functional analysis of heterotrimeric G protein subunits in G .…”

“…It is interesting to note that the requirement of the Gβ and Gγ subunits for infection in different fungal plant pathogens varies. For example, it has been previously demonstrated that GBB1 in Gibberella monoliformis is not required for pathogenicity whist the orthologous protein in the related Fusarium oxysporum is [19,20]. Our data clearly show that gene encoding for the Gβ subunit, Gba1 , is required for S. nodorum to cause disease on wheat.…”
