Radioimmuno‐ and radioreceptor assays were developed for quantitating fusicoccin‐like substances in plants. FC‐like ligands were found in cultured horseradish roots (70–90 pmol/g) and headed cabbage leaves (9–11 pmol/g). Detection of FC‐like ligands in sterile root culture further argues in favour of endogenous fusicoccin representing a new type of phytohormone.
