In situ studies of the ultrastructure of the Cyanobacteria in the coralloid roots of Encephalartos arenarius, E. transvenosus and E. woodii (Cycadales)

Phycologia, 1989
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 root regeneration on Macrozamia megagametophites

Giornale botanico italiano, 1980
Abstract Megagametophytes of Macrozamia communis were incubated in White's Basal Medium and in White's Basal Medium modified with 2,4-D and kinetin. On the medium enriched with growth substances, regeneration of coralloid roots was induced. These are morphologically identical to sporophytic coralloid roots, without any endosymbiont and displaying ...

Antiviral activity of coralloid root ofCycas revoluta extract against some viruses of tomato plant

Experientia, 1984
Crude coralloid root extract ofCycas revoluta showed significant antiviral activity against viruses of the tomato plant (PVX, PVY, TMV, TAV and TRSV) when applied 24 h before virus inoculation, or when mixed with different virus inocula before virus inocultion, in hypersensitive and systemic hosts.

Coralloid Root Systems in Plants showing Lime-induced Chlorosis

Nature, 1967
LIME-INDUCED chlorosis is a well known nutritional disorder of species growing on calcareous soils. The overt symptoms are the development of interveinal chloroses, which are commonly more severe in young leaves. Only in severe cases are the veins themselves chlorotic.
