【 摘 要 】

References(23)Cited-By(35)Two novel Chlamydomonas mutants, ida5 and ida6, that lack subsets of inner-arm dynein have been isolated and mapped to discrete loci on the right arm of linkage group XIV. Of the seven different innerarm dynein subspecies (a, b, c, d, e, /and g) identified by ion-exchange chromatography, ida5 lacks a, c, d ande, while ida6 lacks e alone; these are the only mutants that have been shown to lack subspecies e. Both strains can swim, albeit more slowly than the wild type. Hence, subspecies e must contribute to flagellar movement although it is unnecessary for the generation of undulating movement.
