A differential response to chemical elicitors in Catharanthus roseus in vitro cultures.
The effects of methyl jasmonate, salicylic acid and ethylene on alkaloid accumulation in in vitro cell suspension, hairy roots and rootless shoot cultures of Catharanthus roseus were analyzed. Ajmalicine, but not catharanthine, accumulation was promoted by jasmonate and ethylene treatments in cell suspensions. In hairy roots, jasmonate induced the accumulation of both alkaloids, whereas ethylene only induced catharanthine accumulation. In shoot cultures, positive effects of jasmonate and ethylene were recorded only in vindoline accumulation. Ethylene diminished catharanthine accumulation in these cultures. No effect of salicylic acid was observed in any of the studied in vitro culture systems.
