Abstract
IN a previous report it was shown that acetic acid and certain other substances could prevent a phototactic response of cells of Chlamydomonas without impairing their motility1. It was of interest to see whether the reverse action could also be obtained, that is, to induce phototaxis in motile cells which do not respond to light. It will be shown that indolyl-3-acetic acid (IAA) and ethylenediamine tetraacetic acid (EDTA) induce such responses.
