• Effects of phenylmethanol (PM), 2-phenylethanol (PE) and 3-phenyl-1-propanol (PP) on the conidiation rhythm and on the fatty acid composition of phospholipids were examined in Neurospora crassa. The period for the conidiation rhythm was shortened in proportion to the concentration used of PE of more than 1 mM. PM at 10 mM and PP at 3 mM, however, did not cause a decrease in the length of the period. PE did not affect the temperature compensation of the length of the period or the amplitude of the phase shift by light. The ratio of linolenic acid to linoleic acid decreased in proportion to the concentrations of PE, PM, and PP in all the phospholipids examined. The proportion of phosphatidic acid+diphosphatidylglycerol to the total phospholipids also was decreased by these compounds. Period shortening by PE can not be explained by the change in the phospholipid fatty acid composition.
