Streptomyces 是一種能夠為植物提供良好保護的細菌,它們駐紮在植物的根部,釋放出不同的物質及抗生素,消滅泥土間對植物有害的細菌。410Please respect copyright.PENANAjnKo0bUhoG

但是,Streptomyces 已知是一種不懂得自我移動的細菌,它們到底是如何抵達植物根部的呢?410Please respect copyright.PENANArPdOaqPnIN

(圖2)雖然Streptomyces 並不懂得自我移動,但它的嬰兒形態(Spore)可以黏附在懂得自我移動的細菌的鞭毛之上,搭順風車在泥土之間行走。410Please respect copyright.PENANAeLejIquzQO

(圖3)研究更發現,Streptomyces spore 是依靠其表面名為Rodlein的蛋白質與其他細菌的鞭毛作出黏貼。410Please respect copyright.PENANAylYTb1xdWn

410Please respect copyright.PENANAYZuu9NmkMc
若果失去Rodlein蛋白質的話,那些Spore亦會因而失去搭順風車的能力。410Please respect copyright.PENANAS7kXXnxRnO
由此可相信,這是其中一道Streptomyces抵達植物根部的機制。410Please respect copyright.PENANAq2Q6qAb4dy

現時多國已打開大門讓各Spore前往理想之地,是否願意往外闖一闖抵達植物根部,還是留守原地等運到,一切也是你的選擇。410Please respect copyright.PENANAAeJs8zOP9b
