Exploring the fossil history of pleurocarpous mosses: Tricostaceae fam. nov. from the Cretaceous of Vancouver Island, Canada

Creator:: Shelton, Glenn W. K., Stockey, Ruth A., Rothwell, Gar W., and Tomescu, Alexandru M. F.
Abstract:: PREMISE OF THE STUDY: Mosses, very diverse in modern ecosystems, are currently underrepresented in the fossil record. For the pre-Cenozoic, fossil mosses are known almost exclusively from compression fossils, while anatomical preservation, which is much more taxonomically informative, is rare. The Lower Cretaceous of Vancouver Island (British Columbia, Canada) hosts...

Middle Jurassic evidence for the origin of Cupressaceae: A paleobotanical context for the roles of regulatory genetics and development in the evolution of conifer seed cones

Creator:: Spencer, Alan R. T., Mapes, Gene, Bateman, Richard M., Hilton, Jason, and Rothwell, Gar W.
Abstract:: Premise of the study: Triassic and Jurassic fossils record structural changes in conifer seed cones through time, provide the earliest evidence for crown-group conifer clades, and further clarify sister-group relationships of modern conifer families. A new and distinct seed-cone from the Isle of Skye in western Scotland provides the oldest...

Fragaria: A genus with deep historical roots and ripe for evolutionary and ecological insights

Creator:: Liston, Aaron, Cronn, Richard, and Ashman, Tia-Lynn
Abstract:: The cultivated strawberry, Fragaria Xananassa, is one of the youngest domesticated plants. Its 18th century origin via hybridization in Europe between the North American F. virginiana and the South American F. chiloensis was documented by the botanist Antoine Nicolas Duchesne. His 1766 “Natural History of Strawberries” is an extraordinary work...

Sequencing and De Novo Transcriptome Assembly of Brachypodium sylvaticum (Poaceae)

Creator:: Fox, Samuel E., Preece, Justin, Kimbrel, Jeffrey A., Marchini, Gina L., Sage, Abigail, Youens-Clark, Ken, Cruzan, Mitchell B., and Jaiswal, Pankaj
Abstract:: PREMISE OF THE STUDY: We report the de novo assembly and characterization of the transcriptomes of Brachypodium sylvaticum (slender false-brome) accessions from native populations of Spain and Greece, and an invasive population west of Corvallis, Oregon, USA. METHODS AND RESULTS: More than 350 million sequence reads from the mRNA libraries...

Bioclimatic, ecological, and phenotypic intermediacy and high genetic admixture in a natural hybrid of octoploid strawberries

Creator:: Salamone, Isabella, Govindarajulu, Rajanikanth, Falk, Stacey, Parks, Matthew, Liston, Aaron, and Ashnam, Tia-Lynn
Abstract:: Premise of the Study: Hybrid zones provide "natural laboratories" for understanding the processes of selection, reinforcement, and speciation. We sought to gain insight into the degree of introgression and the extent of ecological-phenotypic intermediacy in the natural hybrid strawberry, Fragaria x ananassa subsp. cuneifolia. Methods: We used whole-plastome sequencing to...

Honeggeriella complexa gen. et sp. nov., a heteromerous lichen from the lower cretaceous of Vancouver Island (British Columbia, Canada)

Creator:: Matsunaga, Kelly K. S., Stockey, Ruth A., and Tomescu, Alexandru M. F.
Abstract:: • Premise of the study: Colonists of even the most inhospitable environments, lichens are present in all terrestrial ecosystems. Because of their ecological versatility and ubiquity, they have been considered excellent candidates for early colonizers of terrestrial environments. Despite such predictions, good preservation potential, and the extant diversity of lichenized...

Contrasting Hydraulic Strategies in Two Tropical Lianas and Their Host Trees

Creator:: Johnson, Daniel M., Domec, Jean-Christophe, Woodruff, David R., McCulloh, Katherine A., and Meinzer, Frederick C.
Abstract:: • Premise of the Study: Tropical liana abundance has been increasing over the past 40 yr, which has been associated with reduced rainfall. The proposed mechanism allowing lianas to thrive in dry conditions is deeper root systems than co-occurring trees, although we know very little about the fundamental hydraulic physiology...

Do Ray Cells Provide a Pathway for Radial Water Movement in the Stems of Conifer Trees?

Creator:: Barnard, David M., Lachenbruch, Barbara, McCulloh, Katherine A., Kitin, Peter, and Meinzer, Frederick C.
Abstract:: • Premise of the study: The pathway of radial water movement in tree stems presents an unknown with respect to whole-tree hydraulics. Radial profi les have shown substantial axial sap fl ow in deeper layers of sapwood (that may lack direct connection to transpiring leaves), which suggests the existence of...

Ontologies as Integrative Tools for Plant Science

Creator:: Walls, Ramona L., Athreya, Balaji, Cooper, Laurel, Elser, Justin, Gandolfo, Maria A., Jaiswal, Pankaj, Mungall, Christopher J., Preece, Justin, Rensing, Stefan, Smith, Barry, and Stevenson, Dennis W.
Abstract:: Premise of the study: Bio-ontologies are essential tools for accessing and analyzing the rapidly growing pool of plant genomic and phenomic data. Ontologies provide structured vocabularies to support consistent aggregation of data and a semantic framework for automated analyses and reasoning. They are a key component of the semantic web....

Arbutus menziesii (Ericaceae) facilitates regeneration dynamics in mixed evergreen forests by promoting mycorrhizal fungal diversity and host connectivity

Creator:: Kennedy, Peter G., Smith, Dylan P., Horton, Tom R., and Molina, Randy J.
Abstract:: • Premise of study: In the mixed evergreen forests in the western United States, Arbutus menziesii is able to quickly resprout following disturbance and, as such, act as a nurse tree during forest regeneration. The mechanism for this nurse tree effect has frequently been ascribed to mycorrhizal fungi, but no...
