The family Potyviridae includes plant viruses with single-stranded, positive-sense RNA genomes of 8-11 kb and flexuous filamentous particles 650-950 nm long 11-20 wide. Genera in the are distinguished by host range, genomic features phylogeny member viruses. Most monopartite, but those members genus Bymovirus bipartite. Some cause serious disease epidemics cultivated plants. This is a summary International Committee on Taxonomy Viruses (ICTV) Report Potyviridae, which available at...
A panel of monoclonal antibodies (MAbs) generated against an admixture 12 potyvirus isolates was used to compare and differentiate diverse potyviruses. Both native denatured virions strains bean yellow mosaic (BYMV), potato virus Y, tobacco etch, pea seed-borne mosaic, iris severe mild asparagus virus-1 potyviruses were as immunogen antigen for screening the hybridoma cell lines. Thirty lines secreting potyvirus-specific reactive in indirect antigen-coated plate (ACP-) ELISA selected...

It is known that four common inbred mouse strains show defects of the forebrain commissures. The BALB/cJ strain has a low frequency abnormally small corpus callosum, whereas 129 have many animals with deficient callosum. I/LnJ and BTBR T+ tf/J never half almost all severely reduced size hippocampal commissure. Certain F1 hybrid crosses among these are to be less abnormal than parents, suggesting parent different genetic causes commissure defects. In this study, were investigated. × I/Ln...
1-Aminocyclopropane-1-carboxylic acid (ACC) synthase (EC 4.4.1.14) is a key enzyme regulating ethylene biosynthesis in higher plants. A monoclonal antibody (mAb T20C) that immunoprecipitates the ACC activity from tomato pericarp tissue extracts revealed mAb T20C immunodecorates an ≈67-kDa polypeptide. On isoelectric focusing gels, cell-free preparations was resolved into three distinct peaks with pI values 5.3, 7, and 9. specifically recognized 7 form of on electrophoretic transfer (Western)...
This collaborative work by over 180 researchers from 40+ countries addresses the challenges posed “phantom agents”—putative pathogenic agents named in literature without supporting data on their existence. Those remain regulatory lists, creating barriers trade and plant certification. Historically identified based solely symptoms, these lack isolates or sequence data, making reliable detection risk assessment impossible. After reviewing 120 such across 10 key genera, we recommend removal...
ABSTRACT Sunflower mosaic is caused by a putative member of the family Potyviridae. virus (SuMV) was characterized in terms host range, physical and biological characteristics, partial nucleotide amino acid sequence. Cells infected with SuMV had cytoplasmic inclusion bodies typical potyviruses. Of 74 genera tested, only species Helianthus, Sanvitalia, Zinnia, all Asteraceae, were systemic hosts. Commercial sunflower hybrids from United States, Europe, South Africa equally susceptible. The...
One major dsRNA of molecular weight (MW) 13.3 × 106 and two others (MW 1.9 0.8 106) were routinely detected by polyacrylamide gel electrophoresis in extracts from sweet orange {Citrus sinensis) or citron (Citrus medica) infected with each 66 isolates citrus tristeza virus (CTV). Several additional also commonly detected, usually as weakly stained bands reproducible positions gels, but some very prominent, e.g., a MW 1.7 associated seedling yellows isolate (sy-1). No was equivalent...
Abstract Viral, bacterial, and fungal diseases of ornamental plants cause major losses in productivity quality. Chemical methods are available for control diseases, to a lesser extent bacterial but there no economically effective chemical controls viral except vector species. Host plant resistance is an means controlling minimizing the necessity application pesticides; however, many ornamentals which natural disease available. It possible introduce derived from other species, or even...
Multiple forms of homoserine dehydrogenase (HSDH) from carrot (Daucus carota L.) have been identified. One form HSDH (T-form) has a relative molecular weight 240,000 and is strongly inhibited by threonine. Another (K-form) 180,000 insensitive to inhibition The interconversion these two dependent upon the presence or absence threonine potassium. Polyacrylamide electrophoretic gels stained for activity protein, paralleled with Western blot analysis, verified T- K-forms in 5 millimolar 100...
