Phytophthora root rot, caused by sojae, is one of the most damaging diseases soybean and introgression Rps (Resistance to P. sojae) genes into elite lines arguably best way manage this disease. Current bioassays phenotype gene-for-gene relationship are hampered with respect reproducibility long-term stability isolates, do not accurately predict horizontal resistance individually. The aim our study was investigate a new phenotyping sojae isolates vertical in that relies on zoospores...
Phytophthora root rot (PRR), caused by the oomycete sojae, is a devastating disease of soybean worldwide, and has been present in Canada since 1950s. Major resistance to P. sojae (Rps) genes have deployed breeders mitigate yield losses, which shifts pathogen population more complex pathotypes emergence new races. This study reports on survey races throughout 203 commercial fields two PRR nurseries province Ontario, Canada, first extensive be conducted late 1980s. A total 22 one intermediate...
Production of soybean in short-season areas Canada is affected by Pythium species causing seed rot, seedling damping-off and root rot under the cool, moist conditions prevalent early growing season. To determine which infect plants these conditions, soil samples were collected 2010, 2011 2012 from fields Ontario where symptoms or observed. spp. isolated using a baiting approach selective media. PCR amplification sequencing internal transcribed spacer nuclear ribosomal DNA allowed for...
Xue, A. G., Chen, Y., Marchand, Guo, W., Ren, C., Savard, M. and McElroy, R. B. 2015. Timing of inoculation Fusarium species affect the severity head blight on oat. Can. J. Plant Sci. 95: 517–524. The influence timing pathogenicity four spp. (F. culmorum, F. graminearum, sporotrichioides, avenaceum) causing (FHB) were examined 12 oat genotypes under controlled environmental conditions in two separate sets experiments. In first set, early inoculations with graminearum at or before complete...
Flocculosin is an antifungal cellobiose lipid linked to the biocontrol activity of Pseudozyma flocculosa and whose structure very similar that ustilagic acid produced by Ustilago maydis. In this work, homologs U. maydis cyp1 gene, involved in biosynthesis acid, were isolated sequenced from P. fusiformata, latter species being also known produce acid. Interestingly, no found four other closely related spp. which evidence production has ever been obtained, thus supporting specificity with...
Two Pseudomonas strains (H346-M and H346-S) were isolated from hazelnut trees showing symptoms of shoot dieback necrosis. The draft genome sequences H346-M H346-S consist 66 51 contigs, respectively, with total sizes 5,693,988 5,889,925 bp 4,885 5,045 protein-coding sequences, respectively.
