RESUMO
The linkage relationship of mutants involved in the synthesis of flagella was determined by PBSl transduction. Mutants that affect the structure of flagellin (hag) and temperature-sensitive mutants (flaTS) that produce flagella when grown at 37 C but not when grown at 46 C were examined. All of the mutants were found to be linked to the hisA1 marker. The flaTS mutants fell into three clusters. Group A contained the majority of mutants which were loosely grouped around the hag locus. Group B mutants were segregated from the hag locus and appeared closely linked to the phage adsorption site gene (gtaA), and group C was only loosely linked to hisA1 and thus far contains only one mutant. A flagella locus (ifm) affecting both the degree of motility and level of flagellation was shown to map near group A. Mutants affecting motility (mot) were not linked to hisA1 by PBSl transduction. Several markers previously shown to link to hisA1 were ordered with respect to hisA1 and the flagellar genes.
