Phylometagenomics of Cycad Coralloid Roots Reveals Shared Symbiotic Signals [PDF]

Microbial Genomics
Cycads are known to host symbiotic cyanobacteria, including Nostocales species, as well as other sympatric bacterial taxa within their specialized coralloid roots. Yet, it is unknown if these bacteria share a phylogenetic origin and/or common genomic functions that allow them to engage in ...

SEM Observations on Cyanobacteria-Infected Cycad Coralloid Roots

South African Journal of Botany, 1988
In Nostoc-infected coralloid roots of the cycads Encephalartos transvenosus Stapf & Burtt Davy and E. paucidentatus Stapf & Burtt Davy the intercellular cyanobacteria are present in a narrow circular band between the outer and the inner cortex only. When the cyanobacterial density is very great, some intracellular infection is present.

Developmental Anatomy of Coralloid Roots in Cycads [PDF]

American Journal of Botany, 1975
Coralloid roots of cycads were found to originate endogenously from the pericycle of apogeotropic secondary roots or adventitious roots that have become exposed or nearly exposed to the soil surface. All mature coralloid roots are susceptible to infection by algal endophytes, which seem to enter from the soil through a break in the dermal layers.In the

On the Phycobionts of the Cycad Coralloid Roots [PDF]

New Phytologist, 1980
SummaryThe structure, ultrastructure and the developmental cycle of the phycobionts living in the coralloid roots of various cycads growing in different Italian Botanical Gardens were studied. The phycobionts were examined in the various zones of the coralloids from the top towards the base. All the phycobionts observed have the characteristics typical

Structure and Physiology of Cycad Coralloid Roots

Giornale Botanico Italiano (Florence, Italy: 1962), 1993
Abstract The gonidial zone organization of coralloid roots of Cycas revoluta is reported together with the taxonomy of cyanobiont, the physiology of the association and the significance of nitrogen fixation. Recent data on gonidial zone composition obtained by microelectrodes and immunogold labeling are referred in order to determine the mechanisms of ...

High Cyanobacterial Diversity in Coralloid Roots of Cycads Revealed by PCR Fingerprinting. [PDF]

FEMS Microbiology Ecology, 2002
The genetic diversity of symbiotic cyanobacteria in coralloid roots of cycads was examined using PCR fingerprinting with primers derived from repetitive sequences. The highest genetic resolution was achieved using the primer corresponding to the short tandemly repeated repetitive sequences. The cyanobacteria were collected from the coralloid roots of a
