Multiple isomers of phosphatidyl inositol monophosphate and inositol bis- and trisphosphates from filamentous fungi.

The range of inositol phosphates and inositol phospholipids present in three filamentous fungi, Neurospora crassa, Fusarium graminearum and Phanerochaete chrysosporium has been investigated by HPLC analysis. The profiles obtained demonstrate that two isomers of phosphatidyl inositol monophosphate are present, and that an apparent complexity in the number of isomers of inositol bis- and trisphosphates is found in filamentous fungi that has not been observed in animal or plant cells.
