Journal ArticleDOI
Bioactive alkaloids in vertically transmitted fungal endophytes
TL;DR: With future research, vertically transmitted fungi from diverse clades with narrow host ranges and that produce bioactive compounds are likely to be found as important mutualists in additional plants.
Journal ArticleDOI
Relationship between the endophyte Embellisia spp. and the toxic alkaloid swainsonine in major locoweed species (Astragalus and Oxytropis).
Michael H. Ralphs,Rebecca Creamer,Deana L. Baucom,Dale R. Gardner,Stanley L. Welsh,J.D. Graham,C. Hart,Daniel Cook,Bryan L. Stegelmeier +8 more
TL;DR: A survey of the major locoweeds from areas where locoweed poisoning has occurred and found species found to contain the fungal endophyte and produce substantial amounts of swainsonine were A. mollissimus, A. cibarius, and O. sericea.
Journal ArticleDOI
Production of the alkaloid swainsonine by a fungal endosymbiont of the Ascomycete order Chaetothyriales in the host Ipomoea carnea.
Daniel Cook,Wesley T. Beaulieu,Ivan W. Mott,Franklin Riet-Correa,Dale R. Gardner,Daniel Grum,James A. Pfister,Keith Clay,Clairton Marcolongo-Pereira +8 more
TL;DR: It is demonstrated that I. carnea plants are infected with a fungal endosymbiont that was cultured from its seeds and which produced swainsonine in pure culture but not the calystegines, which are glycosidase inhibitors.
Journal ArticleDOI
Production of the alkaloid swainsonine by a fungal endophyte in the host Swainsona canescens.
Daniel Grum,Daniel Cook,Deana L. Baucom,Ivan W. Mott,Dale R. Gardner,Rebecca Creamer,Jeremy G. Allen +6 more
TL;DR: Swainsona canescens is shown to harbor an endophyte that is closely related to Undifilum species previously cultured from locoweeds of North America and Asia, and was characterized as an UndifILum species using morphological and phylogenetic analyses.
Journal ArticleDOI
Norditerpene alkaloid concentrations in tissues and floral rewards of larkspurs and impacts on pollinators
Daniel Cook,Jessamyn S. Manson,Jessamyn S. Manson,Dale R. Gardner,Kevin D. Welch,Rebecca E. Irwin,Rebecca E. Irwin +6 more
TL;DR: It is suggested that nectar with low alkaloid concentrations may be beneficial to plant fitness by limiting adverse effects on pollinator activity and optimal defense theory.
