The Living Fossil Psilotum nudum Has Cortical Fibers With Mannan-Based Cell Wall Matrix.
Chernova T, Ageeva M, Mikshina P, Trofimova O, Kozlova L, Lev-Yadun S, Gorshkova T. Chernova T, et al. Front Plant Sci. 2020 Apr 28;11:488. doi: 10.3389/fpls.2020.00488. eCollection 2020. Front Plant Sci. 2020. PMID: 32411161 Free PMC article.
In an effort to partially fill this gap, we studied the fibers and the composition of cell walls in stems of the sporophyte of the living fossil Psilotum nudum. Various types of light microscopy, combined with partial tissue maceration demonstrated that this perennial, roo …

Diverse chalcone synthase superfamily enzymes from the most primitive vascular plant, Psilotum nudum.
Yamazaki Y, Suh DY, Sitthithaworn W, Ishiguro K, Kobayashi Y, Shibuya M, Ebizuka Y, Sankawa U. Yamazaki Y, et al. Planta. 2001 Nov;214(1):75-84. doi: 10.1007/s004250100586. Planta. 2001. PMID: 11762173
Psilotum nudum Griseb is a pteridophyte and belongs to the single family (Psilotaceae) of the division, Psilophyta. ...This cluster of pteridophytes is located next to the cluster formed by pine (gymnosperm) enzymes, in agreement with their evolutionary relationships. P …

Phylogenetic affinity of arbuscular mycorrhizal symbionts in Psilotum nudum.
Winther JL, Friedman WE. Winther JL, et al. J Plant Res. 2009 Sep;122(5):485-96. doi: 10.1007/s10265-009-0234-8. Epub 2009 Jun 10. J Plant Res. 2009. PMID: 19513803
Our goal was to isolate and phylogenetically identify the AM fungi associated with both the autotrophic and underground mycoheterotrophic life cycle phases of Psilotum nudum. Phylogenetic analyses recovered 11 fungal phylotypes in four diverse clades of Glomus A that form …
