Supplementary Figure 1.

Yeast complementation assay showing the Magnaporthe APT2 gene is unable to complement the cold sensitive phenotype of the Saccharomyces cerevisiae Deltadrs2 mutant.

Supplementary Figure 2.

Influence of MgAPT2(p) expression on aminophospholipid internalisation in intact yeast cells. MgAPT2(p) is unable to restore the ability of drs2Delta to internalize phosphatidylserine.

Supplementary Figure 3.

Generation and virulence of DeltaMgapt2 mutants. Targeted gene replacement strategy showing the generation of 6 gene replacement transformants. Subsequent plant infection assays and epidermal penetration assays show a significant reduction of DeltaMgapt2 mutants to cause rice blast disease.

Supplementary Figure 4.

Electron micrographs showing the accumulation of Berkeley bodies in the yeast drs2Delta mutant.

Supplementary Figure 5.

The loss of MgAPT2 has no affect on endocytosis. Wild type and DeltaMgapt2 conidia were stained with FM4-64 and show no significant difference in uptake kinetics.

Supplementary Figure 6.

The DeltaMgapt2 mutant is impaired in its ability to secrete alpha-amylase. Using an anti-alpha-amylase antibody, immunogold experiments were conducted. The resulting electron micrographs show DeltaMgapt2 is severely reduced in alpha-amylase secretion.

Supplementary Figure 7.

Plate assay showing DeltaMgapt2 mutants are not compromised in their ability to secrete the enzyme trehalase.

Supplementary Table 1.

Amino acid similarity and identity of MgAPT2 and the yeast aminophospholipid translocases.

Supplementary Table 2.

Table showing the ability of the DeltaMgapt2 mutant to grow on single carbon sources.

Supplementary Table 3.

Summary of Magnaporthe strains used in the study.

Supplementary Methods.

Comprehensive and detailed explanation of protocols used in the study together with references.
