RESUMO

Silver, Warren S. (University of Florida, Gainesville). Root nodule symbiosis. I. Endophyte of Myrica cerifera. J. Bacteriol. 87:416–421. 1964.—Electron microscopy of 0.1-μ thick sections of root nodules, fixed with permanganate and embedded with methacrylate, showed that infected plant cells were filled with a mycelial endophyte. The endophyte was filamentous, 1 μ in diameter, septate, and had an enlarged, club-shaped terminus. Although structurally the endophyte strongly resembles an actinomycete, it was not isolated in pure culture on a variety of appropriate media.
