摘要：

Suspension cultures of Coleus blumei (Lamiaceae) treated with either an elicitor preparation from the culture medium of the phytopathogenic oomycete Pythium aphanidermatum or with methyl jasmonate enhanced accumulation of rosmarinic acid approximately threefold. The specific activities of phenylalanine ammonia lyase and rosmarinic acid synthase were also enhanced after addition of the fungal elicitor. The addition of methyl jasmonate transiently increased activities of phenylalanine ammonia lyase and hydroxyphenylpyruvate reductase, whereas the activity of rosmarinic acid synthase was not stimulated and the activity of tyrosine aminotransferase was slightly and constantly enhanced. Methyl jasmonate stimulated rosmarinic acid accumulation not only when added directly to the culture medium, but also when it could reach the cells only via the gas phase.
