Fire effects on wetland prairie species : final report

Creator:: Clark, Deborah L., Wilson, Mark V., and Clark, Deborah Louise, 1950-
Abstract:: Wetland prairies of the Willamette Valley, considered among the rarest of Oregon’s ecosystems, are threatened by invasion of woody species and non-native species. Because of its historical importance, fire is a top choice of managers for preventing the encroachment of woody species. However, the effects of prescribed burning on present...

Kinetic and Spectroscopic Analysis of the Inactivating Effects of Nitric Oxide on the Individual Components of Azotobacter vinelandii Nitrogenase

Creator:: Hyman, Michael R., Seefeldt, Lance C., Morgan, Vance, Arp, Daniel J., and Mortenson, Leonard E.
Abstract:: The effects of nitric oxide (NO) on the individual components of Azotobacter vinelandii nitrogenase have been examined by kinetic and spectroscopic methods. Incubation of the Fe protein (Av2) for 1 h with stoichiometries of 4- and 8-fold molar excesses of NO to Av2 dimer resulted in a complete loss of...

Acetylene Inhibition of Azotobacter vinelandii Hydrogenase: Acetylene Binds Tightly to the Large Subunit

Creator:: Sun, Jin-Hua, Hyman, Michael R., and Arp, Daniel J.
Abstract:: Acetylene is a slow-binding inhibitor of the Ni- and Fe-containing dimeric hydrogenase isolated from Azotobacter vinelandii. Acetylene was released from hydrogenase during the recovery from inhibition. This indicates that no transformation of acetylene to another compound occurred as a result of the interaction with hydrogenase. However, the release of C2H2...

Debilitation of Plant Potyvirus Infectivity by P1 Proteinase-Inactivating Mutations and Restoration by Second-Site Modifications

Creator:: Verchot, Jeanmarie and Carrington, James C.
Abstract:: Tobacco etch virus (TEV) encodes three proteinases that catalyze processing of the genome-encoded polyprotein. The P1 proteinase originates from the N terminus of the polyprotein and catalyzes proteolysis between itself and the helper component proteinase (HC-Pro). Mutations resulting in substitution of a single amino acid, small insertions, or deletions were...

Complementation of tobacco etch potyvirus mutants by active RNA polymerase expressed in transgenic cells

Creator:: Li, Xiao Hua and Carrington, James C.
Abstract:: A genetic complementation system was developed in which tobacco etch virus (TEV) polymerase (NIb)- expressing transgenic plants or protoplasts were inoculated with NIb-defective TEV mutants. A β-glucuronidase (GUS) reporter gene integrated into the genomes of parental and four mutant viruses was used to assay RNA amplification. Two mutants (termed VNN...

Cap-Independent Enhancement of Translation by a Plant Potyvirus 5' Nontranslated Region

Creator:: Carrington, James C. and Freed, Deon D.
Abstract:: The RNA genome of tobacco etch virus (TEV), a plant potyvirus, functions as an mRNA for synthesis of a 346-kilodalton polyprotein that undergoes extensive proteolytic processing. The RNA lacks a normal 5' cap structure at its terminus, which suggests that the mechanism of translational initiation differs from that of a...

Evidence that the Potyvirus P1 Proteinase Functions in trans as an Accessory Factor for Genome Amplification

Creator:: Verchot, Jeanmarie and Carrington, James C.
Abstract:: The tobacco etch potyvirus (TEV) polyprotein is proteolytically processed by three viral proteinases (NIa, HC-Pro, and P1). While the NIa and HC-Pro proteinases each provide multiple functions essential for viral infectivity, the role of the P1 proteinase beyond its autoproteolytic activity is understood poorly. To determine if P1 is necessary...

Analysis of the VPg-Proteinase (NIa) Encoded by Tobacco Etch Potyvirus: Effects of Mutations on Subcellular Transport, Proteolytic Processing, and Genome Amplification

Creator:: Schadd, Mary C., Haldeman-Chahill, Ruth, Cronin, Stephen, and Carrington, James C.
Abstract:: A mutational analysis was conducted to investigate the functions of the tobacco etch potyvirus VPgproteinase (NIa) protein in vivo. The NIa N-terminal domain contains the VPg attachment site, whereas the C-terminal domain contains a picornavirus 3C-like proteinase. Cleavage at an internal site separating the two domains occurs in a subset...

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...
