Disassociation of oogonia formation from oospore production inPhytophthora cactorum by sterols with varying side chain lengths
- 12 Downloads
A series of 20(R)-n-alkylpregn-5-en-3β-ols with 0 to 9 (but not with 12) C-atoms in the alkyl group induced formation of oogonia inPhytophthora cactorum. However, maturation of the oogonia into germinating oospores occurred only when the alkyl group had 4–7 C-atoms.

The chromatographic and mass spectral properties of the sterols reisolated fromP. cactorum were similar to those reported by Joseph. See also Nes, W. R., Joseph, J. M., Landrey, J. R., and Conner, R. L., J. biol. Chem.255 (1980) 11815. Procedures for isolation and quantitation are to be found in Nes, W. D., Sanders, G. A., and Heftmann, E., Lipids16 (1981) 744. The control cultures were found to contain small amounts of cholesterol by GLC and GLC-MS as was the Difco agar (derived from red algae which synthesize cholesterol). Thus, the occurrence of a few oogonia in the control is presumably due to the remnants of cholesterol left in the agar after its industrial processing.Google Scholar
