Summary
An electron microscopic examination of eight non-flagellate strains of S. typhimurium revealed that an H1 (amber) mutant produced flagellar hooks and basal structures indistinguishable from those associated with the proximal end of normal flagella. No flagella-related structures were seen in strains with mutations in fla genes A, B, C, D, F, K or M. A mutant of a new fla complementation group, flaR, produced abnormal structures, termed “superhooks”, which resemble the hooks of normal flagella assembled end-to-end. The mutant locus, flaR, maps between flaM and flaAIII.
