In response to the vast loss of prairie area in western and southern Minnesota and the concern over plant genetic loss and soil erosion that resulted, this study set to determine the success of prairie reconstruction along Minnesota roadways. Areas around rest stops on major highways were seeded with prairie plants. As nitrogen is commonly limited in natural environments, legumes-known for thei...

HSU, S., and R. N. GOODMAN. 1978. Production of host-specific, wilt-inducing toxin in apple cell suspension cultures inoculated with Erwinia amylovora. Phytopathology 68: 351-354. A wilt-inducing toxin was detected in filtrates prepared of the virulent bacteria paralleled production of the toxin in from apple cell suspension cultures (ACSC) which had been the suspension cultures. The virulent s...

The use of selected starter culture is widely diffused in winemaking. In pure fermentation, the ability of inoculated Saccharomyces cerevisiae to suppress the wild microflora is one of the most important feature determining the starter ability to dominate the process. Since the wine is the result of the interaction of several yeast species and strains, many studies are available on the effect o...

Visna virus inoculation of mice before immunization with unrelated antigens caused suppression of humoral and cell-mediated immune responses. The immunosuppressive effect was dependent on the virus dose and time of administration. The number of "background" antibody-producing spleen cells increased slightly after inoculation of Visna virus. Heat treatment of Visna virus abolished its immunosupp...

Transmissible viral proventriculitis (TVP) was experimentally reproduced in 2-wk-old specific-pathogen-free chickens and commercial broiler chickens by eyedrop inoculation of adenovirus-like virus (AdLV), isolate R1 1/3. No clinical signs and no weight gain depression were observed in chickens inoculated with AdLV (R11/3); however, gross and microscopic lesions characteristic of TVP were presen...

Background: Groundnut bud necrosis virus (GBNV) (Tospovirus genus, Bunyaviridae family) infects the major crops of solanaceae, leguminosae and cucurbitaceae in India. Temperature is an important factor which influences the plant growth and development under diseased conditions.Objective: In the present study, we evaluated the effect of four different temp...
