 Title    Are Polyphosphoinositides Involved in Signal Transduction of Elicitor-Induced Phytoalexin Synthesis in Cultured Plant Cells?  
 Abstract    The phospholipids of cultured parsley and soybean cells were labelled with myo-[2-3H]inositol, [2-3H]glycerol or [32P]orthophosphate. By one-and two-dimensional chromatographic compari­ son of the labelled phospholipids with reference substances, the presence of l-(3-sn-phos-phatidyl)-D-myo-inositol 4-phosphate and l-(3-sn-phosphatidyl)-D-myo-inositol 4,5-bisphosphate was demonstrated in these cultures. These results were corroborated by analysis of the deacyla-tion products. Cells were labelled with either myo-[2-3H]inositol, [2-3H]glycerol or [32P]ortho-phosphate and subsequently challenged with elicitor for various lengths of time. Radioactivity in individual phosphoinositides from these cells was determined. No significant influence of elicitor-challenge of either soybean or parsley cells on incorporation of 3H or 32P into polyphospho­ inositides was found between 0.5 and 20 min after elicitor addition.
