The structure of the root nodules of Ceanothus sanguineus and Ceanothus velutinus, with special reference to the endophyte. Amer. Jour. Bot. 46(10): 698–703. Illus. 1959.—Past studies of non-leguminous root nodules have cited the endophytes of these structures as bacteria, filamentous fungi, actinomycetes, and members of the Plasmodiophorales. In this study, nodules of Ceanothus sanguineus and of Ceanothus velutinus were examined by using a variety of fixatives and staining methods as checks against artifacts, as well as histochemical tests and phase-contrast microscopy of living material. It was concluded that the nodules of these species were modified short roots, not homologous with leguminous nodules, inhabited by a filamentous microorganism which resembled most closely members of the described genus Streptomyces. The thallus of the endophyte had a definite, firm wall structure which absorbed ruthenium red stain actively, thus indicating a high pectin content.
