Abstract

Summary: Mutations were induced in the unicellular green alga Gerloff by ultraviolet irradiation. The majority of mutants detected were slow-growing types which did not respond to organic supplements in the medium, and palmelloid forms in which flagellated cells were not produced, or only occurred in small numbers. Among biochemical mutants, one exhibited impairment of the photosynthetic mechanism, and two were vitamin-dependent, respectively requiring -aminobenzoic acid (PABA) and aneurin for growth. Some mutants were distinguished by features of cell contents, cell form, or mode of cell division, while in others motility of the cells was restricted by the absence or paralysis of the flagella.
