Comparative Genomics of a Plant-Pathogenic Fungus, Pyrenophora tritici-repentis, Reveals Transduplication and the Impact of Repeat Elements on Pathogenicity and Population Divergence

Creator:: Manning, Viola A., Pandelova, Iovanna, Dhillon, Braham, Wilhelm, Larry J., Goodwin, Stephen B., Berlin, Aaron M., Figueroa, Melania, Freitag, Michael, Hane, James K., Henrissat, Bernard, Holman, Wade H., Kodira, Chinnappa D., Martin, Joel, Oliver, Richard P., Robbertse, Barbara, Schackwitz, Wendy, Schwartz, David C., Spatafora, Joseph W., Turgeon, B. Gillian, Yandava, Chandri, Young, Sarah, Zhou, Shiguo, Zeng, Qiandong, Grigoriev, Igor V., Ma, Li-Jun, and Ciuffetti, Lynda M.
Abstract:: Pyrenophora tritici-repentis is a necrotrophic fungus causal to the disease tan spot of wheat, whose contribution to crop loss has increased significantly during the last few decades. Pathogenicity by this fungus is attributed to the production of host-selective toxins ( HST), which are recognized by their host in a genotype-specific...

A Lower Cretaceous (Valanginian) seed cone provides the earliest fossil record for Picea (Pinaceae)

Creator:: Klymiuk, Ashley A. and Stockey, Ruth A.
Abstract:: Premise of study: Sequence analyses for Pinaceae have suggested that extant genera diverged in the late Mesozoic. While the fossil record indicates that Pinaceae was highly diverse during the Cretaceous, there are few records of living genera. This description of an anatomically preserved seed cone extends the fossil record for...

The Seed Cone Eathiestrobus gen. nov.: Fossil Evidence for a Jurassic Origin of Pinaceae

Creator:: Rothwell, Gar W., Mapes, Gene, Stockey, Ruth A., and Hilton, Jason
Abstract:: Premise of the study: Pinaceae and nonpinoid species are sister groups within the conifer clade as inferred from molecular systematic comparisons of living species and therefore should have comparable geological ages. However, the fossil record for the nonpinoid lineage of extant conifer families is Triassic, nearly 100 million years older...

Response of the nitrogen-fixing lichen Lobaria pulmonaria to phosphorus, molybdenum, and vanadium

Creator:: Marks, Jade A., Pett-Ridge, Julie C., Perakis, Steven S., Allen, Jessica L., and McCune, Bruce
Abstract:: Nitrogen-fixing lichens (cyanolichens) are an important source of nitrogen (N) in Pacific Northwest forests, but limitation of lichen growth by elements essential for N fixation is poorly understood. To investigate how nutrient limitation may affect cyanolichen growth rates, we fertilized a tripartite cyanobacterial lichen (Lobaria pulmonaria) and a green algal...

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...

Developing Models for the Forage Ratios of Culiseta melanura and Culex erraticus using Species Characteristics for Avian Hosts

Creator:: Estep, Laura K., McClure, Christopher J. W., Burkett-Cadena, Nathan D., Hassan, Hassan K., Unnasch, Thomas R., and Hill, Geoffrey E.
Abstract:: Studies of mosquito preferences for avian hosts have found that some bird species are at greater risk than others of being fed upon by mosquitoes. The ecological factors that determine this interspecific variation in avian host use by mosquitoes have been little studied, despite the possibility that such variation may...

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...

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...

Burial increases seed longevity of two Artemisia tridentata (Asteraceae) subspecies

Creator:: Wijayratne, Upekala C. and Pyke, David A.
Abstract:: • Premise of the study: Seed longevity and persistence in soil seed banks may be especially important for population persistence in ecosystems where opportunities for seedling establishment and disturbance are unpredictable. The fire regime, an important driver of population dynamics in sagebrush steppe ecosystems, has been altered by exotic annual...

Abandoning Sverdrup’s critical depth hypothesis on phytoplankton blooms

Creator:: Behrenfeld, Michael J.
Abstract:: The Critical Depth Hypothesis formalized by Sverdrup in 1953 posits that vernal phytoplankton blooms occur when surface mixing shoals to a depth shallower than a critical depth horizon defining the point where phytoplankton growth exceeds losses. This hypothesis has since served as a cornerstone in plankton ecology and reﬂects the...
