The motile behavior of a gliding diatom, Nitzschiya communis , was analyzed with the intention of comparing it with that of cyanobacteria. As in cyanobacteria, ethionine suppressed reversals, Ca 2+ increased the frequency of reversals, and an uncoupler prevented the effect of Ca 2+ . Light caused methylation of a peptide with an apparent M r of 60000. Methylation that was analogous to cyanobacterial could be produced in the dark by duroquinol, a reductant of plastoquinone, while Ca 2+ blocked methylation.
