In the course of screening search for plant growth regulators, a culture filtrate of Streptomyces graminofadens 3C02 was found to inhibit the growth of lettuce seedlings. The active substances, named rotihibin A (1) and B (2), were revealed to be lipo-peptidal compounds. Rotihibins inhibit growth of various plants at below 1 μg/ml, but do not show lethal activity even at higher doses.
在筛选植物生长调节剂的过程中,发现链霉菌(Streptomyces graminofadens)3C02的培养滤液能够抑制生菜苗的生长。活性物质被命名为rotihibin A (1)和B (2),被证实为脂肽化合物。Rotihibins在低于1 μg/ml的浓度下抑制多种植物的生长,但即使在更高剂量下也没有表现出致死活性。
