| Popis: | Spontaneous mutants affecting the morphology and pigmentation of the small marine red alga Champia parvula were genetically characterized. All of the variants were transmitted in the Mendelian pattern expected for recessive nuclear mutations. The results permit the identification of four mutant genes affecting morphology and four mutant genes affecting pigmentation. One of the latter, designated yell, was interesting in that it also appeared to act as a recessive lethal during carposporophyte development. So linkage bas been discovered in crosses conducted thus far. Champia parvula was found to have many desirable features for genetic studies, especially a very rapid sexual life cycle, and it is suggested that this species should be considered as a possible model organism for future genetic studies on the Rhodophyta or for teaching seaweed genetics. |
