Free Sugar Profile in Cycads

open access: yesFrontiers in Plant Science, 2014
The sugars fructose, glucose, maltose, and sucrose were quantified in seven tissues of Zamia muricata Willd. to determine their distribution throughout various organs of a model cycad species, and in lateral structural roots of 18 cycad species to ...

Draft Genome Sequence of the Nitrogen-Fixing and Hormogonia-Inducing Cyanobacterium Nostoc cycadae Strain WK-1, Isolated from the Coralloid Roots of Cycas revoluta [PDF]

open access: yes, 2018
We report here the whole-genome sequence of Nostoc cycadae strain WK-1, which was isolated from cyanobacterial colonies growing in the coralloid roots of the gymnosperm Cycas revoluta .

Diatom, contributors of coralloid speleothems, from Togawa-Sakaidani-Do Cave in Miyazaki Prefecture, Central Kyushu, Japan [PDF]

open access: yes, 1987
Coralloid speleothems are commonly distributed in Togawa-Sakaidani-do Cave in Miyazaki Prefecture, Central Kyushu, but their speleological study has not heretofore been achieved. Light and scanning microscopes analyses revealed that coralloid speleothems

Encephalartos lanatus-associated bacteria and extracellular enzyme activities improve soil nutrition in nutrient-deficient grassland ecosystems

open access: yesScientific African
Encephalartos lanatus, commonly called ‘Olifants River Cycad’, is slow-growing and thrives in nutrient-deficient and acidic grassland soils. Like other Encephalartos spp., E.

Partial mycoheterotrophy: a common strategy in arbuscular mycorrhizal plants?

open access: yesNew Phytologist, Volume 251, Issue 6, Page 3096-3110, September 2026.
Proposed autotrophy to mycoheterotrophy continuum among arbuscular mycorrhizal plants. Summary The vast majority of land plants transfer part of the organic carbon they produce by photosynthesis to arbuscular mycorrhizal (AM) fungi inside their root cells; the fungi in turn help plants to take up nutrients and water from the soil.

Occurrence of Phytophthora cinnamomi in the Rhizosphere of Declining Leucadendron elimense subsp. salteri in South Africa

open access: yesForest Pathology, Volume 56, Issue 4, August 2026.
ABSTRACT Phytophthora cinnamomi is a destructive invasive plant pathogen reported from more than 5000 hosts and across all continents except Antarctica. In South Africa, P. cinnamomi poses a substantial threat to native flora, particularly members of the Proteaceae.

Conserved symbiosis‐associated genes in the cycad Encephalartos natalensis suggest co‐option for cyanobacterial symbiosis

open access: yesNew Phytologist, Volume 251, Issue 4, Page 2168-2185, August 2026.
The heterocyst‐rich Encephalartos natalensis cyanobacterial zone in coralloid root suggests co‐option of conserved symbiosis‐associated genes. This figure was created in BioRender (BioRender.com/https://BioRender.com/n3qveqc). Summary Plant‐cyanobacterial symbioses have evolved independently at least four times across land plants, yet their underlying ...
