Phylogenetic results are generally consistent with prior phylogenetic hypotheses. Key results: Phylogenies estimated from both data sets had nearly identical topologies.Finally, evolution of root architecture, flower color, and ergot alkaloid presence was examined. Divergence times were estimated using three fossil calibration points.
Phylogenies were estimated using alignments of 82 plastid genes and whole plastomes. Methods: Whole plastomes were sequenced for 29 morning glory species, representing major lineages.We used whole plastomes to infer relationships across Ipomoeeae. Therefore, systematic research is focused on the monophyletic tribe Ipomoeeae (ca. Phylogenetic studies demonstrated that the largest morning glory genus, Ipomoea, is not monophyletic, and nine other genera are derived from within Ipomoea. Premise of the study: Morning glories are an emerging model system, and resolving phylogenetic relationships is critical for understanding their evolution.Please refer to the Comparison sheet for details.

SEQUENCHER UGA FREE
This keeps the pump free from water and other contaminants present in air. Measuring high concentrations of low mass gases (hydrogen, helium, etc.) is no longer a problem.Īn optional valve and inlet to the turbo pump's exhaust is available for users who wish to vent with dry nitrogen (or other inert gases). This architecture allows corrosive gases (chlorine, fluorine, etc.) to be analyzed without damaging the RGA and turbo pump, and virtually eliminates the problem of back streaming. Separate diaphragm pumps are used to handle the bypass flow and backing of the turbo pump. During bakeout, the system can be heated to 120 ☌. The UGA system is equipped with individual heaters for the vacuum chamber (including RGA), the turbo pump connector, and the vacuum inlet assembly. The U LT series is a simplified design for less demanding applications.Īn optional multi-port sampling inlet consists of 16 manifold-mounted valves that can be used with a variety of capillaries.
The chassis design allows the instrument to be operated vertically or horizontally, and both front-panel and computer operation are supported.
These analyzers are also simple to operate and maintain. UGA applications include semiconductor exhaust gas monitoring, glove box analysis, fuel cell studies, Freon detection, pollution monitoring, fermentation studies and general R&D vacuum analysis. Whether you're measuring trace-level contaminants, solvents, hydrocarbons, refrigerants or corrosive gases, your Universal Gas analyzer is up to the task. They are ideal for on-line monitoring and analysis of gas mixtures. The UGA and U LT Series Universal Gas Analyzers are state-of-the-art bench top mass spectrometers that operate from above atmospheric pressure to UHV.
