Using an auxin‐responsive mutant of Sacchairomyces ellipsodeus , expansion growth of cells caused by auxin was studied especially in comparison with that of protoplasts.1 Indole‐3‐acetic acid induced detectable cell expansion growth in 3 hours in a buffered simple solution where no cell division occurred. 2 The auxin‐induced expansion growth was inhibited by an antiauxin, trans‐ cinnamic acid. 3 Actinomycin D, chloramphenicol and cycloheximide inhibited the auxin‐induced cell expansion growth. 4 Protoplasts did not expand in response to auxin under the condition where intact cells did. 5 The stability of protoplasts was not changed by the low auxin concentration (20 mg/1) which induced cell expansion. 6 High concentrations (100–1000 mg/1) of auxin caused protoplasts to burst even under an osmotically stable condition.
