Signalling pathway in appressorium formation in Magnaporthe grisea

We identified a synthetic hexapeptide that blocks Magnaporthe grisea appressorium formation, in artificial hydrophobic surface. The results suggest that peptides interfere with surface recognition.
M. grisea non pathogenic pth1 mutants were complemented by N. crassa orthologous gene suggesting that the biochemical function of pth1 has not evolved specifically to play a role in appressorium development.
