Evolutionary relationships among Pinus (Pinaceae) subsections inferred from multiple low-copy nuclear loci

Creator:: Syring, John, Willyard, Ann, Cronn, Richard, and Liston, Aaron
Abstract:: Sequence data from nrITS and cpDNA have failed to fully resolve phylogenetic relationships among Pinus species. Four low‐copy nuclear genes, developed from the screening of 73 mapped conifer anchor loci, were sequenced from 12 species representing all subsections. Individual loci do not uniformly support either the nrITS or cpDNA hypotheses...

Incompatibility reactions and nuclear condition of three Phellinus species

Creator:: Hennon, Paul E.
Abstract:: Phellinus arctostaphyli (Long) Niemela, P. igniarius (L. ex Fr.) Quel., and P. tremulae (Bond.) Bond. et Boriss., heartrotting hymenomycetes in the family Hymenochaetaceae (Aphyllophorales), all conform to a multi-allelic heterothallic mating system. Both compatible and incompatible reactions result from pairings of homokaryons from the same basidiocarp. Homokaryons isolated from different...

Systematics of the genus Rhizopogon inferred from nuclear ribosomal DNA large subunit and internal transcribed spacer sequences

Creator:: Grubisha, Lisa C.
Abstract:: Rhizopogon is a hypogeous fungal genus that forms ectomycorrhizae with genera of the Pinaceae. The greatest number and species of Rhizopogon are found in coniferous forests of the Pacific Northwestern United States, where members of the Pinaceae are also concentrated. Rhizopogon spp. are host-specific primarily with Pinus spp. and Pseudotsuga...

Internal transcribed spacer region evolution in Larix and Pseudotsuga (Pinaceae)

Creator:: Gernandt, David S. and Liston, Aaron
Abstract:: The nuclear ribosomal DNA (nrDNA) internal transcribed spacer (ITS) region has been characterized in the sister genera Larix and Pseudotsuga (Pinaceae). Complete sequences were obtained for seven species of Larix from North America and Eurasia and five species of Pseudotsuga from western North America and eastern Asia. ITS region lengths...

Repeat intercontinental dispersal and Pleistocene speciation in disjunct Mediterranean and desert Senecio (Asteraceae)

Creator:: Coleman, Max, Liston, Aaron, Kadereit, Joachim W., and Abbott, Richard J.
Abstract:: To explore the biogeographic history of Mediterranean/arid plant disjunctions, Old and New World Senecio sect. Senecio were analyzed phylogenetically using nuclear ribosomal DNA sequences (ITS). A clade corresponding to sect. Senecio was strongly supported. Area optimization indicated this clade to be of southern African origin. The Mediterranean and southern African...

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...

Progress report II: Restoring prairies: A synthesis of studies on vegetation and invasive species in support of effective management (Year two)

Creator:: Clark, Deborah Louise, 1950- and Wilson, Mark V.
Abstract:: Willamette Valley wetland and upland prairies are some of the most endangered ecosystems in the United States, and provide habitat for many federally listed species. Because these are dynamic systems, subject to ecological succession and invasion by aggressive non-native species, prairies require active management to maintain management goals. This is...

Preliminary Genomic Characterization of Ten Hardwood Tree Species from Multiplexed Low Coverage Whole Genome Sequencing

Creator:: Staton, Margaret, Best, Teodora, Khodwekar, Sudhir, Owusu, Sandra, Xu, Tao, Xu, Yi, Jennings, Tara, Cronn, Richard, Arumuganathan, A. Kathiravetpilla, Coggeshall, Mark, Gailing, Oliver, Liang, Haiying, Romero-Severson, Jeanne, Schlarbaum, Scott, and Carlson, John E.
Abstract:: Forest health issues are on the rise in the United States, resulting from introduction of alien pests and diseases, coupled with abiotic stresses related to climate change. Increasingly, forest scientists are finding genetic/genomic resources valuable in addressing forest health issues. For a set of ten ecologically and economically important native...

The effects of univalent cations on the inductive formation of nitrate reductase

Creator:: Nitsos, Ronald Eugene
Abstract:: An investigation was undertaken to determine whether potassium is indeed necessary for the in vivo synthesis of a specific protein. The effects of univalent cations on the inductive formation of nitrate reductase and on the level of activity of representative non-adaptive enzyme are presented. Cultures of Neurospora crassa were grown...

Influence of site, soil, and inoculum density on dwarf bunt (Tilletia controversa Kühn) of winter wheat

Creator:: Clark, Deborah Ann, 1954-
Abstract:: Field microplot studies conducted over two seasons (1982-1984) evaluated the influence of four physically and chemically diverse soils collected from Pacific Northwest wheat fields on the incidence of dwarf bunt of winter wheat caused by Tilletia controversa Kuhn. These soils were placed at Flora and Pendleton, Oregon to determine the...
