摘要: Streptomyces sp. WXC菌株是从滑桃树(Trewia nudiflora L.)种子中分离到的一株内生菌。提取植物种子的化学成分,对其进行溶剂分组,检测各组分对内生放线菌S. sp. WXC的生长、代谢和活性化合物的影响,结果表明,滑桃树种子水溶性提取物Water ext.对S. sp. WXC的生长、次生代谢产物和活性化合物都有明显的促进作用。

Abstract: Streptomyces sp. WXC was an endophytic strain isolated from the seed of Trewia nudiflora. Trewia nudiflora seed chemical components were extracted and classified. The results showed that the production of frenolicin B was induced by the addition of the Water ext., which was correlated to the upregulation of growth and secondary metabolites. Therefore, we speculated that the inducible production of the antifungal frenolicin B may be an important adaptation mechanism allowing the symbiont, S. sp. WXC, to affect its host, T. nudiflora, through the function of symbiotic chemical defense.
