Biochemical and histological investigations of viral localisation in the hypersensitive reaction of Phaselous vulgaris L. var Pinto to tobacco mosaic virus infection

STOBBS, Lorne,W ABSTRACT Biochemical and Histological Investigations of viral localisation in the hypersensitive reaction of Phaseolus vulgaris L. var Pinto to tobacco mosaic virus infection. The infection of Phaseolus vulgaris L. var Pinto with tobacco mosaic virus (TMV) results in the production of distinct necrotic lesions confining the virus to restricted areas of the leaf surface. Biochemical and histological changes in the leaf tissue as a result of infection have been described. Trace accumulations of fluorescent metabolites, detected prior to lesion expression represent metabolites produced, by the cell in response to virus infection. These substances, are considered to undergo oxidation and in diffusing into adjacent cells, react with cellular constituents causing the death of these cells. Such cellular necrosis in advance of infection effectively limits virus spread. Chromatographic studies on extracts from TMV infected Pinto bean leaf tissue suggests that a number of extra-fluorescent metabolites produced on lesion'expression represent end products of phenolic oxidation r,eactionsoccurring earlier in these cells. Inhibition of phenolic oxidation by ascorbate infiltration or elevated temperature treatment resulted in the absence of extra-fluorescent metabolites and the continued movement of virus in the absence of necrosis. Further studies with i ascorbate infiltration indicated that irreversible necrotic events were determined as early as 12 tci 18 hrs after viral inoculation. Histochemical tests indicated that callose formation was initiated at this time, and occurred in response to necrotisation. Inhibition of necrosis by either ascorbate infiltration or elevated temp8rature treatment resulted in the absence of callose deposition. Scanning electron'micrographs of infected tissue revealed severe epidermal and palisade cell damage. Histochemical tests indicated extensive callose formation in cells bordering the lesion, and suggested the role of callose iTh the blockage of intercellular connections limiting virus movement. The significance of these cellular changes is discussed. ii

Bell Family Bible, Deaths, Tyrrell, 1886-1908

The Deaths page from the Bell Family Bible listing the deaths of Jane Tyrrell in 1886, William C. Tyrrell in 1898, and Lewis Tyrrell in 1908. This Bible was in the possession of the Rick Bell family of St. Catharines, Ontario. Relatives of the Bell family were former Black slaves from the United States who settled in Canada.The handwritten entry appears to read as follows: "Jane Tyrrell, died March 1st 1886 age 64 yrs. William C. Tyrrell died January 15th 1898 by accident in Albany N.Y. age 33 yrs 3 months Lewis Tyrrell died September 25th 1908 at his late residence Vine and Welland Ave. St. Catharines age 81 yrs 5 months." There are various spellings of the Tyrrell name within the Bell family archive. Other forms of the name include Tyrell, Tyrrill, and Terrell.

Niagara Postcards, 1902, 1908, 1910, undated.

Consists of 33 postcards featuring various scenes and landmarks in the Niagara region. The postcards feature the Great Gorge Route, the Niagara River and Falls, Queenston Heights, Ridley College, military camps in Niagara-on-the-Lake, and a Catholic Church in Port Colborne. Most of the postcards are blank, but four have been postmarked. One of these is addressed to Miss Ada Misner, Espanola, Ont., from M.G. and is postmarked August 18, 1908. Another postcard is addressed to Mr. Alfred H. Smith, Stamford Hill, London N., from Hedley Smith, France and is postmarked 1902. Another is addressed to Miss Annabel Bishop, Buffalo, N.Y. from Irene Lalour(?), and is postmarked April 30, 1908. The last postcard is addressed to Miss Edna Lackie, Toronto, from R.M. and is postmarked August 1, 1910.
