Cycloartenol-derived sterol biosynthesis in the Peronosporales [PDF]

open access: yesProceedings of the National Academy of Sciences of the United States of America, 1982
Selected species of the order Peronosporales, which are unable to epoxidize squalene and thus synthesize sterols, are able to metabolize exogenous cycloartenol to lanosterol and in some organisms to fucosterol, ergosterol, and cholesterol.
