Analysis of ribosomal DNA sequences of Polymyxa species and related fungi and the development of genus- and species-specific PCR primers
Ward, Elaine; Adams, M. J. (1998-08)A region of about 800 bp of ribosomal DNA has been sequenced in 10 isolates of Polymyxa and one isolate each of Plasmodiophora brassicae and the chytrid Olpidium brassicae. This region consists of about 330 bp at the 3' ... -
Development and Application of Molecular Methods for the Study of Polymyxa betae
Mutasa-Gottgens, Euphemia; Chwarszczynska, D. M.; Williams, G.; Ward, E.; Adams, M. J.; Asher, M. J. C. (American Society of Sugar Beet Technologists, 1996)A simple method for cloning Polymyxa betae DNA from infected sugar-beet roots has been developed and used to isolate a multi-copy genomic DNA fragment, pPbKES-1, located on at least four different P. betae chromosomes. ... -
Emergence and partial characterization of rice stripe necrosis virus and its fungus vector in South America
Morales, F. J.; Ward, Elaine; Castano, M.; Arroyave, J. A.; Lozano, I.; Adams, M. J. (1999-10)A new disease of rice, known as 'entorchamiento' (crinkling), was first noticed in the Department of Meta, Colombia, in 1991. Symptoms include seedling death, foliar striping and severe plant malformation. Tissue extracts ... -
Polymyxa graminis and the cereal viruses it transmits : a research challenge
Kanyuka, K.; Ward, Elaine; Adams, M. J. (2003-09)Polymyxa graminis is a eukaryotic obligate biotrophic parasite of plant roots that belongs to a poorly studied discrete taxonomic unit informally called the 'plasmodiophorids'. P. graminis is nonpathogenic, but has the ... -
A sensitive DNA-probe for the detection of polymyxa-betae in sugar-beets roots
Mutasa-Gottgens, Euphemia; Ward, Elaine; Adams, M. J.; Collier, C. R.; Chwarszynska, D. M.; Asher, M. J. C. (1993-11)A Polymyxa betae genomic DNA fragment of 1·9 kb has been cloned from infected sugar beet roots and shown to contain DNA sequences that are repeated on at least four different chromosomes. A probe generated from this fragment ...
