Discovery of a novel small secreted protein family with conserved N-terminal IGY motif in Dikarya fungi.

ABSTRACT:

Background

Small secreted proteins (SSPs) are employed by plant pathogenic fungi as essential strategic tools for their successful colonization. SSPs are often species-specific and so far only a few widely phylogenetically distributed SSPs have been identified.

Results

A novel fungal SSP family consisting of 107 members was identified in the poplar tree fungal pathogen Marssonina brunnea, which accounts for over 17% of its secretome. We named these proteins IGY proteins (IGYPs) based on the conserved three amino acids at the N-terminus. In spite of overall low sequence similarity among IGYPs; they showed conserved N- and C-terminal motifs and a unified gene structure. By RT-PCR-seq, we analyzed the IGYP gene models and validated their expressions as active genes during infec
