Abstract
Casuarina glauca develops proteoid (cluster) roots in response to Fe deficiency. This study set out to investigate the possible involvement of ethylene in the initiation and/or the morphogenesis of cluster roots (CR). For this purpose, the effect of Ag+ added as silver thiosulfate, an inhibitor of ethylene action has been studied in plants growing hydroponically. No CR formation was observed in these growth conditions. Inhibition of ethylene biosynthesis by aminoethoxyvinylglycine, 1- aminoisobutyric acid, aminoxyacetic acid or cobalt chloride also eliminated the positive effect of Fe deficiency on CR formation in C. glauca. CR were not formed in Fe- deficient roots in the presence of ethylene inhibitors, suggesting a role for ethylene in the morphological responses to Fe deficiency. Interestingly, treatment of Casuarina plants with the ethylene precursor 1-aminocyclopropane-1-carboxylic acid stimulated significantly the formation of CR, even if plants are supplied with Fe. However, this stimulation did not reach the level of CR obtained in Fe-deficient plants. These results suggest that an ethylene-mediated signalling pathway is involved in CR formation process in C. glauca.
