Abstract
THE morphology of the root nodules of Podocarpus has attracted more attention than that of any other non-leguminous plant, and the nodules have been regarded as a response to infection by bacteria1–4 or by non-septate fungi5–10. The endophyte is considered not to be causal by recent workers11,12, but the nodules are thought to be arrested lateral roots with the cortex renewed annually. Attempts by Baylis et al.11 to maintain Podocarpus seedlings in sterile culture long enough to permit nodule development were unsuccessful, although nodules were formed in cultures which proved to be entirely free from fungi. We have investigated the production of root nodules in sterile culture.
