Twenty-eight of the highly infection-regulated genes showed sequence similarities to proteins in the PHI-base, including the members of the DUF3129 Pfam domain family that encode the gas1 proteins of the rice blast fungus Magnaporthe oryzae[38], an extracellular cutinase (PBC1) from a plant pathogen [39], a tetraspanin homolog from Colletotrichum lindemuthianum[40], and RBT4 from C. albicans[41]. This evidence concerns the gene GAS1 and infection.
