Summary
Thirteen nutritionally deficient mutants have been found amongst 22,553 plants raised from X-ray irradiated spores of the liverwort Sphaerocarpos donnellii Aust. Of the thirteen mutants four require nicotinic acid two choline and four arginine. Two strains must be supplemented with glucose but one is distinguishable by its pale green colour. One strain requires yeast extract in addition to glucose. The auxotrophic mutants of Sphaerocarpos donnellii identified in these studies are discussed in relation to those already found in other green plants, viz. Chlamydomonas reinhardi, Chl. eugametos, Marchantia polymorpha, Physcomittella patens, Todea barbara, Arabidopsis thaliana, and Lycopersicum esculentum.
