NOTES Phenocopies of a Heteromorphous Flagellar Mutant in Salmonella MICHIKO MITANI' AND TETSUO IINO National Inistitute of Genetics, Mishima, Japan Received for publication 18 July 1966 So-called "curly" bacterial flagella are characterized by having half the wavelength of normal flagella. It has been shown that, in a medium containing p-fluorophenylalanine (FPA) in place of phenylalanine (PA), a normally flagellated strain of Salmonella regenerates curly flagella after the normal flagella have been removed by shaking (D. Kerridge, Biochim. Biophys. Acta 21:593, 1959). Among other Salmonella mutants with aberrant flagellar forms, a "heteromorphous" mutant has been described which regularly produces some cells (about 2%) with a flagellum made up of both normal and curly portions within a clone of normally flagellated cells (T. lino and M. Mitani, J. Gen. Microbiol. 44:27, 1966). We report now the induction of phenocopies of this heteromorphous mutant in a medium containing
