Teliospores were manually cracked under a stereo microscope prior to adding to the PCR reaction mixture. Amplification product was obtained using primers for either a portion of the nuclear ribosomal intergenic spacer region or a portion of the mitochondria) DNA. Collections of teliospores from Tilletia indica, Tilletia barclayana, Tilletia controversa, Tilletia tritici, Tilletia laevis and an unidentified Tilletia sp, from Lolium varied in the proportion of spores from which amplification product could be detected, with the success rate ranging from 100 to 10%. This technique avoids the difficulty and time delay in having to germinate teliospores prior to extracting DNA from a mycelial matte and thus will be of great value in the application of PCR methods for regulatory testing and phylogenetic studies of Tilletia species.","PeriodicalId":9607,"journal":{"name":"Canadian Journal of Plant Pathology-revue Canadienne De Phytopathologie","volume":"73 1","pages":"78-80"},"PeriodicalIF":0.0,"publicationDate":"1999-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72947867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The manures (chicken, 66 t/ha; swine, 55 hLJha; cattle, 100 t/ha) were spread in the spring of 1996 and incorporated with a Rototiller to a depth of 15 cm. Survival of Verticillium dahliae microsclerotia (MS) was determined by burying nylon mesh bags containing MS in the plots. After 4 weeks, the MS were plated on agaz medium. Soil samples collected after incorporation of manures were brought back to the laboratory and used for concurrent laboratory experiments. Ten-gram amounts of soil were placed into test tubes, bags of MS buried in the soil,and survival measured under controlled conditions. Potatoes were planted in the field 1 month after amendment. Potatoes were planted in 1997 and 1998 without any further treatment. verticillium wilt incidence was determined by isolation of V.dahliae from petioles.

Characterization of these isolates according to mating type and sensitivity to metalaxyl revealed the changing nature of P. infestans populations in Canada. In 1994, isolates of the traditional Al, metalaxyl-sensitive (MS) phenotype were common, but by 1996, they were no longer recovered from any tissue samples. Isolates of the A2 mating type, which were predominantly insensitive to metalaxyl (MI), were prevalent in 1996, except in British Columbia (B.C.). In B.C., Al isolates highly insensitive to metalaxyl predominated. Isolates of the Al, MI phenotype were also found in a sample of tomatoes from Ontario in 1996.

Five MAbs reacted with native PVA, three of them also with PVA-CP. MAb 534 gave no reaction in dot-blot tests. In Western blot analysis only MAbs 151, 290, and 328 reacted with PVA-CP. Competition binding test data confirm mutual spatial proximity of epitopes corresponding to these MAbs. Pepscan (SPOTs tests) with overlapping octapeptides representing the sequence of the first 60 amino acids from the N terminus of PVA-CP showed that the epitopes detected by MAb 151, 328, and 634 are located in this region. MAb 534 was deduced to react with discontinuous CP epitope. Results of analogic peptide synthesis for the MAb 151 epitope indicate that two lysine residues are essential for binding of this MAb to its epitope. Our polyclonal antibodies against PVA reacted with six different regions in this part of the CP.","PeriodicalId":9607,"journal":{"name":"Canadian Journal of Plant Pathology-revue Canadienne De Phytopathologie","volume":"5 1","pages":"221-226"},"PeriodicalIF":0.0,"publicationDate":"1998-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87328092","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The protein profiles of pooled and individual samples were analyzed. SDS-PAGE analysis showed the presence of a 19-kDa protein band in infected susceptible foliage. Partial N-terminal amino acid sequence analysis revealed that this band was a mixture of histone and a Cro r I protein. The Cro r I protein was fungus- derived, while the origin of histone was not clear. Utilizing fungal-specific monoclonal antibodies, we determined that about 90% of susceptible seedlings had fungal antigens, while only one resistant seedling showed the presence of fungal antigens. This illustrated the potential use of these monoclonal antibodies as probes in screening seedlings for susceptibility. In addition, significantly greater amounts of seasonally regulated Pin I I protein was found in the foliage of resistant versus susceptible seedling...","PeriodicalId":9607,"journal":{"name":"Canadian Journal of Plant Pathology-revue Canadienne De Phytopathologie","volume":"20 1","pages":"308-318"},"PeriodicalIF":0.0,"publicationDate":"1998-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81951807","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
