Isolation and characterization of 1-palmitoyl-2-linoleoyl-sn-glycerol as a hormogonium-inducing factor (HIF) from the coralloid roots of Cycas revoluta (Cycadaceae). [PDF]
Sci Rep, 2019 AbstractCoralloid roots are specialized tissues of cycads (Cycas revoluta) that are involved in symbioses with nitrogen-fixing Nostoc cyanobacteria. We found that a crude methanolic extract of coralloid roots induced differentiation of the filamentous cell aggregates of Nostoc species into motile hormogonia. Hence, the hormogonium-inducing factor (HIF)

Cyanobiont diversity within coralloid roots of selected cycad species [PDF]
FEMS Microbiology Ecology, 1999 The diversity and host specificity of the cyanobionts of several cycad species (Cycas circinalis L., C. rumphii Miq., Encephalartos lebomboensis I. Verd., E. villosus Lem., and Zamia pumila L.) collected in a botanical garden were examined using the tRNALeu(UAA) intron sequence as a genetic marker.

Horticulturae, 2023 Cinnamon is a tree introduced to the lowlands of Mexico in the mid-16th century, but it spread to other places at the beginning of the 20th century due to its important commercial value as an aromatic spice.

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

Sequence based data supports a single Nostoc strain in individual coralloid roots of cycads [PDF]
FEMS Microbiology Ecology, 2004 The genetic diversity of cyanobacteria associated with cycads was examined using the tRNA(Leu) (UAA) intron as a genetic marker. Coralloid roots of both natural populations of the cycad Macrozamia riedlei (Fischer ex Gaudichaud-Beaupré) C.A. Gardner growing in Perth, Australia and cycads growing in greenhouses, also in Perth, were used and their ...

The Coralloid Roots of Macrozamia Communis L. Johnson [PDF]
Australian Journal of Biological Sciences, 1965 Macrozamia communis exhibits root dimorphism, possessing both normal and coralloid roots. The latter are pneumatophores in which an algal zone may be present or absent. In the coralloid roots the root cap tissue was interpreted as forming a secondary cortex which persisted throughout the life of the root.

Specialized bacteriome uncovered in the coralloid roots of the epiphytic gymnosperm, Zamia pseudoparasitica [PDF]
Environmental DNA, 2020 AbstractEpiphytes face several constraints regarding nutrient acquisition: They are disconnected from soil minerals and they have to mainly rely on nutrients leached by precipitation and microbes. The cycad, Zamia pseudoparasitica Yates, is the only known strictly epiphytic gymnosperm, and it is endemic to Panamanian rainforests.

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.

Characterization of gonidial zone ofCycas revolutacoralloid roots by means of microelectrodes [PDF]
FEMS Microbiology Letters, 1993 Microelectrodes were used for measurements of oxygen, ammonium, potassium and calcium concentrations within gonidial zones of Cycas revoluta coralloid roots. Gonidial zone segments contained an oxygen pressure of 85% with respect to its concentration in the atmosphere.
