Infection of susceptible mouse strains with BeAn, a less virulent strain of Theiler's murine encephalomyelitis virus (TMEV), results in immune system-mediated demyelinating lesions in the central nervous system (CNS) similar to those in multiple sclerosis. Since macrophages appear to carry the major detectable antigen burden in vivo, and purification of sufficient cell numbers from the CNS for ...

WU, FANG-SHENG, and H. H. MURAKISHI. 1978. Infection and synthesis rate of southern bean mosaic virus in soybean callus cells under selected cultural conditions. Phytopathology 68:1389-1392. Soybean (Glycine max 'Harosoy 63') callus cells grown in with that of Prince bean callus treated identically or with either Eriksson's or Linsmaier and Skoog's media were infected soybean plants grown in th...

Cucumber mosaic virus (CMV) is a tripartite, positive-sense RNA plant virus in the genus Cucumovirus, family Bromoviridae. This virus is one of the most economically important viruses affecting several crop plant species and it has one of the widest host ranges among the characterized viruses. Recently, snap bean (Phaseolus vulgaris L.) and pepper (Capsicum annuum L.) crops in Wisconsin have ex...

Two types of inclusion bodies were consistently observed under light microscopy in bean (Phaseolus vulgaris) leaf tissue infected with Bean rugose mosaic virus (BRMV), a species of the genus Comovirus, family Comoviridae. One type consisted of vacuolated inclusions found mainly in the cytoplasm of epidermal cells. The other type consisted of abundant crystalloid inclusions of different sizes an...

Improving digestibility of roughage cell walls will improve ruminant animal performance and reduce loss of nutrients to the environment. The main digestibility impediment for dicotyledonous plants is highly lignified secondary cell walls, notably in stem secondary xylem, which become almost non-digestible. Digestibility of grasses is slowed severely by lignification of most tissues, but these c...

In a greenhouse experiment, two strains of plant growth promoting rizobacteria (PGPR) mixture of (ICARDA-441 and ARC-202) as seed inoculants, and white willow (Salix alba) extract as foliar and seed treatment were tested for induction systemic acquired resistance (SAR) in faba bean plants against Bean yellow mosaic virus (BYMV). The results demonstrated that BYMV challenged plants emerged from ...

Over 200 diseases with different etiologies have been determined in dry beans and green beans. However, viral seem to cause the greatest economic da-mage legume production most parts of world. Dry can be infected by 44 viruses including Bean common mosaic virus (BCMV), necrosis (BCMNV), yellow (BYMV) Cucumber (CMV). Transmission through seeds and/or spread aphids non-persistent manner play impo...
