Mutations in more than 30 genes affect motility in Caulobacter crescentus. We have determined the chromosomal map locations for 27 genes involved in flagellar morphogenesis (fla), three genes involved in flagellar function (mot), and three genes that have a pleiotropic effect on both motility and bacteriophage resistance (ple). Three multigene clusters have been detected at widely separated chromosomal locations, but in addition, there are 12 fla and mot genes that are found at eight additional sites scattered around the C. crescentus chromosome. Thus, there is more scatter of genes involved in flagellar structure and function than has been observed in other bacterial systems.
30多个基因的突变会影响新月柄杆菌的运动能力。我们已经确定了27个参与鞭毛形态发生的基因(fla)、3个参与鞭毛功能的基因(mot)以及3个对运动能力和噬菌体抗性都有多效性影响的基因(ple)在染色体图谱上的位置。在染色体上广泛分离的位置检测到了三个多基因簇,但此外,在新月柄杆菌染色体周围散布的另外八个位点还发现了12个fla和mot基因。因此,与其他细菌系统相比,参与鞭毛结构和功能的基因分布更为分散。
