摘要：A developmental mutant of C. crescentus with altered polar surface structures has been isolated. The mutant lacks a flagellum and pili, and may have an abnormal DNA phage receptor site. A revertant regains the normal structures simultaneously. This point mutation allows normal flagellin synthesis, stalk formation, equatorial cell division, and rate of growth. The mutant phenotype indicates that the assembly of the polar surface structures is coordinately regulated and independent of mechanisms regulating cell polarity and division.
