As a process, … WebA role for a predicted PMO, HAM-7, is required for chemotropic interactions and functions through the cell wall integrity (CWI) MAP kinase signaling pathway in filamentous fungi. Strains lacking ham-7 fail to undergo cell fusion and thus lack an interconnected hyphal network. The ham-7 gene and its relatives form a unique clade among PMOs in fungi.
