Incomplete flagellar structures in Escherichia coli mutants.
Abstract
Incomplete flagellar structures in Escherichia coli mutants. T Suzuki and Y Komeda ABSTRACT Escherichia coli mutants with defects in 29 flagellar genes identified so far were examined by electron microscopy for possession of incomplete flagellar structures in membrane-associated fractions. The results are discussed in consideration of the known transcriptional interaction of flagellar genes. Hook-basal body structures were detected in flaD, flaS, flaT, flbC, and hag mutants. The flaE mutant had a polyhook-basal body structure. An intact basal body appeared in flaK mutants. Putative precursors of the basal body were detected in mutants with defects in flaM, flaU, flaV, and flaY. No structures homologous to the flagellar basal body or its parts were detected in mutants with defects in flaA, flaB, flaC, flaG, flaH, flaI, flaL, flaN, flaO, flaP, flaQ, flaR, flaW, flaX, flbA, flbB, and flbD. One flaZ mutant had an incomplete flagellar basal body structure and another formed no significant structure, suggesting that flaZ is responsible for both basal body assembly and the transcription of the hag gene.
