    • A first glimpse at genes important to the Azolla–Nostoc symbiosis 

      Pryer, Kathleen; Eily, Ariana; Li, FW (Symbiosis, 2019-01-01)
      © 2019, Springer Nature B.V. Azolla is a small genus of diminutive aquatic ferns with a surprisingly vast potential to benefit the environment and agriculture, as well as to provide insight into the evolution of ...
    • A Unified Approach to Taxonomic Delimitation in the Fern Genus Pentagramma (Pteridaceae) 

      Pryer, Kathleen M; Schuettpelz, E; Windham, MD (Systematic Botany, 2015-01-01)
      © Copyright 2015 by the American Society of Plant Taxonomists.The native goldback and silverback ferns of western North America, composing the genus Pentagramma, are phylogenetically isolated within the xeric-adapted cheilanthoid ...
    • Adiantumshastense, a new species of maidenhair fern from California. 

      Huiet, L; Lenz, M; Nelson, JK; Pryer, Kathleen M; Smith, AR (PhytoKeys, 2015)
      A new species of Adiantum is described from California. This species is endemic to northern California and is currently known only from Shasta County. We describe its discovery after first being collected over a century ...
    • An Exploration into Fern Genome Space. 

      Banks, JA; Der, JP; Gitzendanner, MA; Li, FW; Marchant, DB; Pryer, Kathleen M; Rothfels, CJ; ... (13 authors) (Genome Biol Evol, 2015-08-26)
      Ferns are one of the few remaining major clades of land plants for which a complete genome sequence is lacking. Knowledge of genome space in ferns will enable broad-scale comparative analyses of land plant genes and genomes, ...
    • Between two fern genomes. 

      Banks, JA; Barker, MS; Der, JP; Duffy, AM; Graham, SW; Hasebe, M; Langdale, J; ... (19 authors) (Gigascience, 2014)
      Ferns are the only major lineage of vascular plants not represented by a sequenced nuclear genome. This lack of genome sequence information significantly impedes our ability to understand and reconstruct genome evolution ...
    • Crowdfunding the Azolla fern genome project: a grassroots approach. 

      Li, FW; Pryer, Kathleen M (Gigascience, 2014)
      Much of science progresses within the tight boundaries of what is often seen as a "black box". Though familiar to funding agencies, researchers and the academic journals they publish in, it is an entity that outsiders rarely ...
    • Gaga, a new fern genus segregated from cheilanthes (pteridaceae) 

      Li, FW; Pryer, Kathleen M; Windham, MD (Systematic Botany, 2012-10-01)
      Ongoing molecular phylogenetic studies of cheilanthoid ferns confirm that the genus Cheilanthes (Pteridaceae) is polyphyletic. A monophyletic group of species within the hemionitid clade informally called the "C. marginata ...
    • Natural hybridization between genera that diverged from each other approximately 60 million years ago. 

      Fraser-Jenkins, CR; Hovenkamp, PH; Johnson, AK; Pryer, Kathleen M; Roskam, HC; Rothfels, CJ; Swofford, DL; ... (8 authors) (Am Nat, 2015-03)
      A fern from the French Pyrenees-×Cystocarpium roskamianum-is a recently formed intergeneric hybrid between parental lineages that diverged from each other approximately 60 million years ago (mya; 95% highest posterior density: ...
    • Phytochrome diversity in green plants and the origin of canonical plant phytochromes. 

      Graham, SW; Li, FW; Mathews, S; Melkonian, M; Pryer, Kathleen M; Rothfels, CJ; Stevenson, DW; ... (9 authors) (Nat Commun, 2015-07-28)
      Phytochromes are red/far-red photoreceptors that play essential roles in diverse plant morphogenetic and physiological responses to light. Despite their functional significance, phytochrome diversity and evolution across ...
    • Sex and the Single Gametophyte: Revising the Homosporous Vascular Plant Life Cycle in Light of Contemporary Research 

      Farrar, DR; Haufler, CH; Moran, R; Pryer, Kathleen M; Schneller, JJ; Schuettpelz, E; Sessa, EB; ... (9 authors) (BIOSCIENCE, 2016-11)
    • The evolutionary history of ferns inferred from 25 low-copy nuclear genes. 

      Burge, DO; Chen, L; Chen, T; DeGironimo, L; dePamphilis, C; Deyholos, M; Graham, SW; ... (23 authors) (Am J Bot, 2015-07)
      UNLABELLED: • PREMISE OF THE STUDY: Understanding fern (monilophyte) phylogeny and its evolutionary timescale is critical for broad investigations of the evolution of land plants, and for providing the point of comparison ...
    • The origin and evolution of phototropins. 

      Graham, SW; Li, FW; Mathews, S; Melkonian, M; Pryer, Kathleen M; Rothfels, CJ; Stevenson, DW; ... (9 authors) (Front Plant Sci, 2015)
      Plant phototropism, the ability to bend toward or away from light, is predominantly controlled by blue-light photoreceptors, the phototropins. Although phototropins have been well-characterized in Arabidopsis thaliana, their ...
