Phenotype: impaired motility

This mutant was isolated by nitrosoguanidine mutagenesis of cells grown in synchronous cultures (12:12 light-dark), at a time approximately 2 hours into the dark cycle. It has a temperature-conditional defect in flagellar function. Cells resemble wild type at permissive temperature (20 degrees) but when shifted to 32 degrees, the flagella detach rapidly. Cells can initiate flagellar reassembly at 32 degrees, but as the flagella elongate they are lost by detachment.

Cells of this mutant cannot form colonies at 32 degrees under constant light, where rapid growth and cell division are required. Cells grown on an alternating 12 h light-dark cycle divide normally.
