Abstract The following results were obtained using a variant yeast strain, N55, which can respond to the cell‐elongating action of auxin. Base analogs of nucleic acids (2‐thiouracil, 8‐azaguanine, and 5‐fluorouracil) inhibited the auxin‐induced elongation of yeast cells only when they were added to the preculture prior to auxin treatment. The inhibitory effect of 2‐thiouracil and 5‐fluorouracil was reversed by uracil and that of 8‐azaguanine by guanine. Actino‐mycin D inhibited the auxin‐induced elongation when given to the culture containing auxin, but not when given to the preculture. The similarity in these respects between yeast and tissues of higher plants is discussed.
