Abstract

Although treatments of smoke-water (SW) have been successfully used for promoting seed germination as well as plant growth, less reports have been documented on the influence of SW on the production of secondary metabolites in endophytes isolated from medicinal plants. The study investigated the effects of SW and its active compound butenolide (KAR1) on the accumulation of lipophilic tanshinones in endophyte Trichoderma atroviride D16 isolated from Salvia miltiorrhiza. Results showed that the mycelia of T. atroviride D16 treated with SW and KAR1 displayed a significant increase (P < 0.05) in the content of tanshinone I, which was evaluated with 2.26-fold (SW) and 1.86-fold (KAR1) of the control on 20 d after treatment. Comparing with the control, the treatment of SW and KAR1 resulted in a significant increase in the content of tanshinone IIA, and the highest levels were observed to be 31.87% (SW 1:2000, v/v) and 17.77% (KAR1 at 10-9 M) on 20 d after treatment. These findings imply the possibility of using SW and KAR1 for enhancing the biosynthesis of tanshinones in T. atroviride D16, and enrich the application of smoke water in the medicinal plant field.

烟水和烟分离的丁烯内酯(KAR1)诱导丹参内生真菌阿特维里木霉D16生物合成丹参酮
尽管烟气水(SW)处理已成功用于促进种子发芽和植物生长,但关于SW对药用植物内生菌次生代谢产物产生的影响的报道较少。研究了SW及其活性化合物丁烯内酯(KAR1)对丹参内生木霉D16亲脂性丹参酮积累的影响。结果表明,用SW和KAR1处理的T.atroviride D16菌丝体中丹参酮I的含量显著增加(P<0.05),处理后20d分别是对照的2.26倍(SW)和1.86倍(KAR1)。与对照组相比,SW和KAR1处理使丹参酮IIA含量显著增加,处理后20天的最高水平分别为31.87%(SW 1:2000,v/v)和17.77%(10-9M时的KAR1)。这些发现暗示了利用SW和KAR1促进T.atroviride D16中丹参酮生物合成的可能性,并丰富了烟水在药用植物领域的应用。
