Abstract Cyanobionts (Nostoc spp.) of Encephalartos have the same general ultrastructure as the free-living Nostoc spp. However, differences between the cyanobionts of the different cycad species were observed. The cyanobiont of E. transvenosus lacks a sheath and gas vesicles. Plate-filament arrays are not present in the cyanobiont of E.

'Coralloid' roots containing blue-green algae occur commonly on the upper root stocks of M. riedlei in natural habitat in Western Australia. Each coralloid mass persists for several seasons; replacement sets form at irregular intervals, especially after fire.

Abstract Cyanophyceae living in the coralloid-roots of the cycad Encephalartos altensteinii cultivated in the Botanical Gardens of Naples (Italy) and grown in culture have been studied by light and electron microscopy. The cells of the coralloids do not appear to be invaded by bacteria and the Cyanophyceae are localized in the intercellular spaces ...

Abstract The present work is a study of the blue-green algae living in the coralloid roots of Macrozamia communis and isolated from Macrozamia communis in culture. The light and electron microscopic study pointed out the distribution of these microorganisms in the cortical area of coralloids and did not reveal any cells invaded by bacteria.
