Evaluating the use of taxonomy in the IUCN Red List

Conservation Biology, EarlyView.
Abstract Taxonomy defines the units that conservationists strive to preserve for future generations. However, the discovery of new species and the taxonomic revision of existing species affect conservation efforts. Despite the importance of taxonomy for a species’ conservation, there is currently no overview of how those leading species extinction risk

Thermogenesis‐derived spatiotemporal microclimates guide pollinator movement to ensure pollination

Journal of Integrative Plant Biology, EarlyView.
Alocasia odora's microclimatic heterogeneity guides Colocasiomyia fly movement within its inflorescence. During the female stage, midday heat in the upper spadix pushes flies down to the cooler female zone. During the male stage, nocturnal warmth in the upper part pulls flies upward and spathe constriction closes the lower female chamber.

Cycads from the Triassic of Antarctica: Permineralized Cycad Leaves [PDF]

International Journal of Plant Sciences, 2007
Permineralized cycad petioles and/or rachides with associated pinnae are described from two Triassic localities in the Queen Alexandria Range, central Transantarctic Mountains, Antarctica. Petiole‐rachides display an inverted‐omega‐shaped arrangement of vascular bundles typical of most genera of extant Cycadales and exarch primary xylem that link them ...

Revisiting the nomenclature of Carludovica microcephala, type species of Dicranopygium (Cyclanthaceae)

TAXON, Volume 75, Issue 4, August 2026.
Abstract The name Carludovica microcephala, basionym of the type species of Dicranopygium (Cyclanthaceae), has long been attributed to J.D. Hooker (1892), based on plants cultivated at the Royal Botanic Gardens, Kew. A reassessment of nineteenth‐century horticultural literature shows that the name had already been validly published 35 years earlier, in

Infestations of Aulacaspis yasumatsui Reduce Asexual Propagation and Transplantation Success of Cycas revoluta Plants

Horticulturae, 2023
Cycad transplantation and asexual propagation by stem cuttings are highly successful horticultural procedures because the manoxylic stems contain copious nonstructural carbohydrates.

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

New 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 ...

Ecological niches and biogeography of nitrogen‐fixing plants in Europe

Plant Biology, Volume 28, Issue 5, Page 1349-1360, August 2026.
Despite sharing N fixation as a common trait, European legume and actinorhizal plant lineages occupy strikingly divergent ecological niches shaped by their evolutionary histories and physiological adaptations. Advanced symbiont control allows IRLC legumes to expand into northern, mesic regions, while non‐IRLC legumes are more common in Mediterranean ...

Using Nuclear Genomic Data to Address Intractable Relationships and Gene Tree Discordance in an Ancient Group of Gymnosperms (Ephedra, Gnetales)

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Low‐copy nuclear genes were used to address the notoriously difficult phylogeny of Ephedra. Additionally, we explored the potential effect of putative paralogy, intra‐locus recombination, and chimeric sequences on phylogenetic estimation. ABSTRACT The evolutionary history of Ephedra L.

Synergistic Effect of Deoxyanthocyanins from Symbiotic Fern Azolla spp. on hrmA Gene Induction in the Cyanobacterium Nostoc punctiforme

Molecular Plant-Microbe Interactions, 2002
The hrmA gene of the N2-fixing cyanobacterium Nostoc punctiforme functions in repressing the formation of transitory motile filaments, termed hormogonia, by plant-associated vegetative filaments.
