Effect of protistan grazing on the frequency of dividing cells in bacterioplankton asemblages

Creator:: Sherr, Barry F., Sherr, Evelyn, and McDaniel, Julie
Abstract:: Grazing by phagotrophic flagellates and ciliates is a major source of mortality for bacterioplankton in both marine and freshwater systems. Recent studies have demonstrated a positive relationship between clearance rate and prey size for bacterivorous protists. We tested the idea that, by selectively grazing the larger (more actively growing or...

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...

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...

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...

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...

Reproductive Failure of Landlocked Atlantic Salmon from New York's Finger Lakes: Investigations into the Etiology and Epidemiology of the “Cayuga Syndrome”

Creator:: Fisher, Jeffrey P., Spitsbergen, Jan M., Getchell, Rodman, Symula, John, Skea, Jack, Babenzein, Mark, and Chiotti, Thomas
Abstract:: We describe a disease syndrome that afflicts larval, landlocked Atlantic salmon Salmo salar from Cayuga Lake, one of central New York's Finger Lakes. Mortality associated with the “Cayuga syndrome” is 98–100%. Death usually occurs between 650 and 850 centigrade degree-days after fertilization, approximately 2–4 weeks before yolk resorption is complete....

Naturally Occurring Thiamine Deficiency Causing Reproductive Failure in Finger Lakes Atlantic Salmon and Great Lakes Lake Trout

Creator:: Fisher, Jeffrey P., Fitzsimons, John D., Combs, Gerald F. Jr., and Spitsbergen, Jan M.
Abstract:: A maternally transmitted, noninfectious disease known as the Cayuga syndrome caused 100% mortality in larval offspring of wild-caught landlocked Atlantic salmon Salmo salar from several of New York's Finger Lakes. Survival of lake trout Salvelinus namaycush from Lakes Erie and Ontario was also impaired, but not until yolk absorption was...

Pathological and Behavioral Manifestations of the “Cayuga Syndrome,” a Thiamine Deficiency in Larval Landlocked Atlantic Salmon

Creator:: Fisher, Jeffrey P., Spitsbergen, Jan M., Iamonte, Tina, Little, Edward E., and Delonay, Aaron
Abstract:: The “Cayuga syndrome” is a maternally transmitted, naturally occurring thiamine deficiency that causes 100% mortality of larval landlocked Atlantic salmon Salmo salar in several of New York's Finger Lakes, Results of multiyear studies to qualify and quantify the neurobehavioral and gross pathological signs of this condition are described, Affected sac...
