科普專欄–薯不揀單 - 三十秒科學–細菌也懂得乘坐順風車

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。543Please respect copyright.ＰＥＮＡＮＡEXouu7u30u

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?543Please respect copyright.ＰＥＮＡＮＡqLl5NB0jIZ

（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。543Please respect copyright.ＰＥＮＡＮＡIl8zMDpyqJ

（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。543Please respect copyright.ＰＥＮＡＮＡfmEJP6OQKw

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。543Please respect copyright.ＰＥＮＡＮＡiG4jYvu2sO
由此可相信，這是其中一道Streptomyces抵達植物根部的機制。543Please respect copyright.ＰＥＮＡＮＡIdYAOR1qt0

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。543Please respect copyright.ＰＥＮＡＮＡEAbxmbAtdL
