Isolation and Characterization of Novel Huperzine-Producing Endophytic Fungi from Lycopodiaceae Species [PDF]

open access: yesJournal of Fungi, 2023
Huperzine A (HupA) is an important drug for treating Alzheimer’s disease (AD) and is primarily extracted from the Huperzia serrata (Lycopodiaceae). Failures in the chemical synthesis of Hup and in vitro culture have put H. serrata in danger of extinction,

Lycophyte transcriptomes reveal two whole-genome duplications in Lycopodiaceae: Insights into the polyploidization of Phlegmariurus [PDF]

open access: yesPlant Diversity, 2022
Lycophytes are an ancient clade of the non-flowering vascular plants with chromosome numbers that vary from tens to hundreds. They are an excellent study system for examining whole-genome duplications (WGDs), or polyploidization, in spore-dispersed ...

Fungal microbiomes associated with Lycopodiaceae during ecological succession [PDF]

open access: yesEnvironmental Microbiology Reports, Volume 15, Issue 2, Page 109-118, April 2023., 2023
Abstract Lycopodiaceae species form an early‐diverging plant family, characterized by achlorophyllous and subterranean gametophytes that rely on mycorrhizal fungi for their nutrition. Lycopodiaceae often emerge after a disturbance, like in the Hochfeld reserve (Alsace, France) where seven lycopod species appeared on new ski trails following a forest ...

No phylogenomic support for a Cenozoic origin of the “living fossil” Isoetes [PDF]

open access: yesAmerican Journal of Botany, Volume 110, Issue 1, January 2023., 2023
Abstract Premise The isoetalean lineage has a rich fossil record that extends to the Devonian, but the age of the living clade is unclear. Recent results indicate that it is young, from the Cenozoic, whereas earlier work based on less data from a denser taxon sampling yielded Mesozoic median ages.

Phyllosphere mycobiome in two Lycopodiaceae plant species: unraveling potential HupA-producing fungi and fungal interactions [PDF]

open access: yesFrontiers in Plant Science
Huperzine A (HupA), a lycopodium alkaloid with therapeutic potential for neurodegenerative diseases such as Alzheimer’s disease, is found exclusively in some species of the Huperzioideae subfamily of Lycopodiaceae.

A metabarcoding protocol targeting two DNA regions to analyze root‐associated fungal communities in ferns and lycophytes [PDF]

open access: yesApplications in Plant Sciences, Volume 11, Issue 3, May-June 2023., 2023
Abstract Premise Detailed studies of the fungi associated with lycophytes and ferns provide crucial insights into the early evolution of land plants. However, most investigations to date have assessed fern–fungus interactions based only on visual root inspection. In the present research, we establish and evaluate a metabarcoding protocol to analyze the

Comprehensive analysis of the Lycopodium japonicum mitogenome reveals abundant tRNA genes and cis-spliced introns in Lycopodiaceae species [PDF]

open access: yesFrontiers in Plant Science
Lycophytes and ferns represent one of the earliest-diverging lineages of vascular plants, with the Lycopodiaceae family constituting the basal clade among lycophytes.
