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.

Rhizopalmoxylon singulare sp. nov. - coralloid palm roots from the Late Cretaceous Deccan Intertrappean beds of Nawargaon, India

Journal of Palaeosciences, 2009
Permineralized coralloid aerial palm roots forming a thick compact mantle have been described from the Deccan Intertrappean beds of Nawargaon, Maharashtra, India. A medium sized root exhibits rhizodermis, thick exodermis, thin outer and wide inner cortex; fibers in the inner cortex; air cavities in 3-7 concentric rings in the middle zone of inner ...

Symbiotic Nitrogen Fixation by Coralloid Roots of the Cycad Macrozamia riedlei : Physiological Characteristics and Ecological Significance

Australian Journal of Plant Physiology, 1976
'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.

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.

A light and electron microscopic study of blue-green algae growing in the coralloid-roots of Encephalartos altensteinii and in culture

Phycologia, 1975
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 ...
