研究了茉莉酸甲酯（MeJA）对甜黄草（Scoparia dulcis）培养组织中类异戊二烯合成的影响。结果发现，茉莉酸甲酯抑制叶绿素，类胡萝卜素，叶绿醇和β-谷甾醇在组织中的积累。然而，MeJA显著地增强了东莨菪碱B（SD B）的产生，其中10 μ M是刺激SD B产生的最佳观察浓度。SDB在MeJA处理后6 d达到最大浓度。
The effects of methyl jasmonate (MeJA) on isoprenoid production were evaluated in cultured tissues of Scoparia dulcis. It was found that MeJA suppressed the accumulation of chlorophylls, carotenoids, phytol and beta-sitosterol in the tissues. MeJA, however, remarkably enhanced the production of scopadulcic acid B (SDB), with 10 microM being optimal observed concentration for stimulation of SDB production. The maximum concentration of SDB was observed 6 d after MeJA treatment.
