Abstract
Slime trails, which are deposited on surfaces by gliding bacteria and which serve as preferential pathways for gliding motility, were tested for the species specificity of their support of movement. Among the pairs of bacteria tested, a variety of gliding bacteria and a flagellated bacterium moved along trails of unrelated species. Thus, the trails did not serve as pheromones. Rather, they may have guided gliding elasticotactically. Some biological implications of this finding are considered.
摘要
黏液痕迹是由滑行细菌沉积在表面上的，并且作为滑行运动的优先路径，研究人员测试了它们对运动支持的物种特异性。在所测试的细菌对中，多种滑行细菌和一种鞭毛细菌沿着不相关物种的痕迹移动。因此，这些痕迹并不是作为信息素起作用。相反，它们可能是以弹性触觉的方式引导滑行。本文考虑了这一发现的一些生物学意义。
