Monoclonal Antibodies to Identify Tomato Mosaic Tobamovirus (tomv)
Monoclonal antibodies were obtained against Tomato mosaic tobamovirus (ToMV) isolated in Brazil. One antibody (8G7G2) isotyped as IgG2b (κ light chain) showed strong specificity and very low cross reaction with the Tobacco mosaic virus (TMV). It can be used in identification of tomato mosaic virus (ToMV).
متن کاملIdentification of Tomato Mosaic Virus Infection in Jasmine
Virus-like symptoms were recently observed on leaves of landscape and nursery downy and star jasmine (Jasminum multijlorum) and wax jasmine (J. gracile) in southeast Florida. Foliar symptoms included mottling, chlorotic ring spots and chlorotic line patterns. An agent was mechanically transmitted with difficulty from symptomatic leaves of downy jasmine to Nicotiana debneyi and N. tabacum 'Xanth...
متن کاملCarboxylate interactions involved in the disassembly of tobacco mosaic tobamovirus.
Structural studies of tobacco mosaic tobamovirus (TMV) have identified two coat protein (CP) intersubunit carboxyl-carboxylate interactions and one CP carboxylate-RNA phosphate interaction whose electrostatic repulsion is believed to drive virion disassembly. In this study, the involvement of each interaction in the disassembly process was examined. Site-directed mutagenesis was used to replace...
متن کاملChanges in Foliar Elements in Red Spruce Seedlings after Exposure to Sulfuric and Nitric Acid Mist
Red spruce (Picea rubens Sarg.) seedlings were exposed repeatedly at a field site or in a greenhouse~to acidic mist containing the major sulfur and nitrogen pollutants of wet deposition in the eastern U.S.: sulfate alone, nitrate alone or with ammonium ion, and a combination of these ions. Acidities and ion concentrations ranged from below the mean to above the maximum concentration for cloudwa...
متن کاملNitrate reductase of primary roots of red spruce seedlings : effects of acidity and metal ions.
Nitrate reductase activity (NRA) was found in primary roots, but not in foliage of red spruce (Picea rubens Sarg.) seedlings. Nitrate induced NRA:NH(4) (+) did not induce and slightly depressed NRA in older seedlings. Induction required 8 hours and, once induced, NRA decreased slowly in the absence of exogenous NO(3) (-). Seedlings were grown in perlite with a complete nutrient solution contain...
