The nexus of decay and birth: Ecological and evolutionary significance of wood‐decaying fungi in green Calypsoinae orchid germination

Functional Ecology, Volume 39, Issue 12, Page 3659-3671, December 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract A key feature of Orchidaceae is the production of dust‐like seeds that depend on fungal carbon during early development. Although protocorms and mature green orchids typically associate with rhizoctonia fungi, many non‐photosynthetic orchids and some photosynthetic ...

Filial Effects of Ephemeral Cycad Seedlings Contribute Nitrogen to the Parents’ Rhizosphere

Ecologies
Most cycad seeds germinate under the parent plant, and seedlings die before recruitment to the juvenile stage. Decomposition of the senesced organs releases the nutrients to influence nutrient cycling.

A first characterization of the leaflet endophytic prokaryotic community in Dioon cycads

Plant Species Biology, Volume 40, Issue 6, Page 547-555, November 2025.
This study presents the first characterization of leaflet endophytic prokaryotic communities in Mexican cycads of the genus Dioon. Using 16S rRNA metabarcoding, we describe the composition and diversity of foliar bacterial communities across species and biogeographic regions, highlighting patterns potentially shaped by environmental conditions.

The identification of the coralloid root endophytes of the southern African cycads and the ability of the isolates to fix dinitrogen

South African Journal of Botany, 1987
Forty-one isolates of the cyanobionts in the coralloid roots of 31 cycad species, which include all the species indigenous to the Republic of South Africa, were identified. One isolate (from Encephalartos hildebrandtii) appears to be a species of Calothrix. All the other isolates were identified as species of Nostoc. Twenty-eight isolates were assigned

Root Growth and Branching of Two Cycas Species Are Influenced by Form of Nitrogen Fertilizer

Agronomy
Horticultural research into the group of plants known as cycads has been deficient, and this includes the study of root growth and function. The form of nitrogen (N) available to plants is known to influence root growth and morphology.

Threats to cycad biocultural heritage in the Amami Islands, Japan

Plant Species Biology, Volume 40, Issue 4, Page 292-310, July 2025.
The central point we seek to frame in this article is that the increasing infestations of cycad aulacaspis scale in the Amami guntō existentially threaten not only the islands' sotetsu but rather entire cultural systems and natural ecologies that have developed around these plants.

Roots of Colophospermum mopane. Are they infected by rhizobia? [PDF]

, 2000
Roots of Colophospermum mopane are infected with bacteria that resemble rhizobia but also show similarities with Frankia spp. The infection causes continuous degeneration of infected roots and stimulates the development of new lateral roots. This results

Biological invasion by the cycad‐specific scale pest Aulacaspis yasumatsui (Diaspididae) into Cycas revoluta (Cycadaceae) populations on Amami‐Oshima and Okinawa‐jima, Japan

Plant Species Biology, Volume 40, Issue 4, Page 280-291, July 2025.
This article details the invasion of cycad aulacaspis scale into the islands of Okinawa‐Jima and Amami‐Oshima. Several recommendations are proposed in this article by members of the IUCN cycad specialist group and experts in the biological control of this scale insect.

Semiconductor‐Bimetallic Plasmonic Heterojunction ZnO−Ag−Cu as Reusable SERS Substrate with Attomolar Detection Limit

Chemistry – An Asian Journal, Volume 20, Issue 9, May 2, 2025.
Easily synthesized, economic, UV‐cleanable semiconductor‐bimetallic plasmonic ZnO‐Ag‐Cu (ZAC) composite shows extraordinary SERS efficiency by detecting analyte molecule R6G distinctly, at attomolar level. The synergy between the metal additives and ZnO results in enhanced plasmonic efficiency, improved charge transfer and useful photocatalytic ...
