Av. Babakov et al., ENDOGENOUS FUSICOCCIN-LIKE LIGAND REVEALED IN HIGHER-PLANTS BY RADIORECEPTOR AND RADIOIMMUNOASSAYS, FEBS letters, 351(2), 1994, pp. 243-245
Radioimmuno- and radioreceptor assays were developed for quantitating
fusicoccin-like substances in plants. FC-like ligands were found in cu
ltured horseradish roots (70-90 pmol/g) and headed cabbage leaves (9-1
1 pmol/g). Detection of FC-like ligands in sterile root culture furthe
r argues in favour of endogenous fusicoccin representing a new type of
phytohormone.
