PLCG1 and infection: Moreover, exo-proteome and transcriptome analyses performed on four non-pathogenic B. cinerea transformants (NPT1/4), almost unaffected in hyphal growth but exhibiting defects in infection cushion formation and medium acidification, showed that BcGIPC-PLC1 was down-accumulated in the four NPT together with many CAZy proteins known to play a major role in the degradation of the plant cell wall33.
