Phylogeny, cospeciation, and host switching in the evolution of the ascomycete genus Rhabdocline on Pseudotsuga and Larix (Pinaceae)

Creator:: Gernandt, David S.
Abstract:: The relative role of cospeciation and host switching in the phylogenetic history of ascomycete foliar symbionts is addressed in the orders Leotiales and Rhytismatales, fungi associated predominantly with Pinaceae (Coniferales). Emphasis is placed on comparing the evolution of the sister genera Pseudotsuga and Larix (Pinaceae) with that of the pathogenic...

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...

Multiplex sequencing of plant chloroplast genomes using Solexa sequencing-by-synthesis technology

Creator:: Cronn, Richard, Liston, Aaron, Parks, Matthew, Gernandt, David S., Shen, Rongkun, and Mockler, Todd
Abstract:: Organellar DNA sequences are widely used in evolutionary and population genetic studies, however, the conservative nature of chloroplast gene and genome evolution often limits phylogenetic resolution and statistical power. To gain maximal access to the historical record contained within chloroplast genomes, we have adapted multiplex sequencing-by-synthesis (MSBS) to simultaneously sequence...

Creator:: Parker, David Bill
Abstract:: Data from the southern Cascade Mountains of Oregon has been collected for application in computer analysis of snowfields. Vegetation type, canopy cover, slope, aspect, insolation, and snowfield ground truth delineation are given consideration. In addition, a procedure for transferral of data onto Landsat imagery was derived.

Creator:: Raju, Vadivukarasi, Rains, Jordan, Gates, Cooper, Luo, Wei, Wang, Xingfeng, Stickle, William F., Stucky, Galen D., and Ji, Xiulei
Abstract:: We, for the first time, demonstrate that orthorhombic V₂O₅ can exhibit superior electrochemical performance in sodium ion batteries when uniformly coated inside nanoporous carbon. The encapsulated V₂O₅ shows a specific capacity as high as 276 mAh/g, while the whole nanocomposite exhibits a capacity of 170 mAh/g. The V₂O₅/C composite was...

Creator:: Wang, Xingfeng, Raju, Vadivukarasi, Luo, Wei, Wang, Bao, Stickle, William F., and Ji, Xiulei
Abstract:: Despite the considerable advances of deposition technologies, it remains a significant challenge to form conformal deposition on surface of nanoporous carbons. Here, we introduce a new ambient hydrolysis deposition method that employs and controls pre-adsorbed water vapor on nanoporous carbons to define the deposition of TiO₂. We converted the deposited...

Use of simultaneous analyses to guide fossil-based calibrations of Pinaceae phylogeny

Creator:: Gernandt, David S., Magallon, Susana, Lopez, Gretel Geada, Flores, Omar Zeron, Willyard, Ann, and Liston, Aaron
Abstract:: Uncertainties in the age and phylogenetic position of Pinaceae fossils present significant obstacles to our understanding of the timing of diversification in the family. We demonstrate that simultaneous phylogenetic analyses of chloroplastDNA(matK and rbcL) and nonmolecular characters that include both extant genera and a limited number of fossil taxa provide...

Abstract:: Na-ion batteries are emerging as one of the most promising energy storage technologies, particularly for grid-level applications. Among anode candidate materials, hard carbon is very attractive due to its high capacity and low cost. However, hard carbon anodes often suffer a low first-cycle Coulombic efficiency and fast capacity fading. In...
