A liberibacter (isolate NZ082226) was detected in a symptomatic tomato plant and subsequently in five other members of the family Solanaceae: capsicum, potato, tamarillo, cape gooseberry and chilli. Phylogenetic analyses of the 16S rRNA gene sequence, the deduced amino acid sequence of the rplJ gene and a partial nucleotide sequence of the beta operon(More)
The Amsterdam Declaration on Fungal Nomenclature was agreed at an international symposium convened in Amsterdam on 19-20 April 2011 under the auspices of the International Commission on the Taxonomy of Fungi (ICTF). The purpose of the symposium was to address the issue of whether or how the current system of naming pleomorphic fungi should be maintained or(More)
Indigenous to Europe, the blackberry rust fungus Phragmidium violaceum was introduced to Australia and subsequently appeared in New Zealand, with the most recent authorised introductions to Australia specifically for the biological control of European blackberry. Markers for 'selective amplification of microsatellite polymorphic loci' (SAMPL) were developed(More)
It is proposed that Agrobacterium radiobacter has priority as the earlier heterotypic (subjective) synonym when it is united with Agrobacterium tumefaciens. The nomenclatural status of A. tumefaciens as a later heterotypic synonym of the united species is not lost and it remains the type species of the genus. Request for an opinion.
Ustilago is a polyphyletic genus of smut fungi found mainly on Poaceae. The development of a taxonomy that reflects phylogeny requires subdivision of Ustilago into smaller monophyletic genera. Several separate systematic analyses have determined that Macalpinomyces mackinlayi, M. tubiformis, Tolyposporella pachycarpa, Ustilago bouriquetii and U. maydis,(More)
