Unlocking a high bacterial diversity in the coralloid root microbiome from the cycad genus Dioon.
PLoS ONE, 2019 Cycads are among the few plants that have developed specialized roots to host nitrogen-fixing bacteria. We describe the bacterial diversity of the coralloid roots from seven Dioon species and their surrounding rhizosphere and soil.

Plant Diversity, 2018 A normalized full-length cDNA library was constructed from the coralloid roots of Cycas debaoensis by the DSN (duplex-specific nuclease) normalization method combined with the SMART (Switching Mechanism At 5′ end of the RNA Transcript) technique.

Characterization of gonidial zone of Cycas revoluta coralloid 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.

Cycad coralloid roots contain bacterial communities including cyanobacteria and Caulobacter spp that encode niche-specific biosynthetic gene clusters [PDF]
Genome Biology and Evolution, 2017 Cycads are the only early seed plants that have evolved a specialized root to host endophytic bacteria that fix nitrogen. To provide evolutionary and functional insights into this million-year old symbiosis, we investigate endophytic bacterial sub ...

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]
Scientific Reports, 2019 Coralloid 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 ...

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.

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.

Nitrogen Fixation in the Coralloid Roots of Macrozamia Communis L. Johnson [PDF]
Australian Journal of Biological Sciences, 1965 Coralloid roots of Macrozamia communis have been shown by the isotopic method to fix nitrogen when they contain the endophytic blue·green algae. Immature coralloid roots devoid of the endophyte did not fix nitrogen. Coralloid roots from glasshouse-grown plants fixed 2· 7 times as much nitrogen when illuminated than they did in the dark and the IfiN ...
