morphological, cultural and pathogenic characteristics of coniothyrium zuluense isolates from different plantation regions in south africa.	coniothyrium canker caused by coniothyrium zuluense, is a serious stem canker disease of eucalyptus species in sub-tropical regions of south africa. this disease is typified by necrotic bark lesions that coalesce to form large kino-impregnated cankers along the stems of trees. the strategy currently used to manage coniothyrium canker in plantations is to deploy eucalyptus species or clones that are resistant to the disease. considerable success has already been achieved in this regard, but the l ...	2002	12617501
first record of colletogloeopsis zuluense comb. nov., causing a stem canker of eucalyptus in china.	coniothyrium zuluense causes a serious canker disease of eucalyptus in various parts of the world. very little is known regarding the taxonomy of this asexual fungus, which was provided with a name based solely on morphological characteristics. in this study we consider the phylogenetic position of c. zuluense using dna-based techniques. distance analysis using 18s and its regions revealed extensive sequence divergence relative to the type species of coniothyrium, c. palmarum and species of para ...	2006	16378717
multiple gene genealogies reveal important relationships between species of phaeophleospora infecting eucalyptus leaves.	the majority of eucalyptus species are native to australia, but worldwide there are over 3 million ha of exotic plantations, especially in the tropics and subtropics. of the numerous known leaf diseases, three species of phaeophleospora can cause severe defoliation of young eucalyptus; phaeophleospora destructans, phaeophleospora eucalypti and phaeophleospora epicoccoides. phaeophleospora destructans has a major impact on seedling survival in asia and has not, as yet, been found in australia whe ...	2007	17250757
multi-gene phylogenies and phenotypic characters distinguish two species within the colletogloeopsis zuluensis complex associated with eucalyptus stem cankers.	colletogloeopsis zuluensis, previously known as coniothyrium zuluense, causes a serious stem canker disease on eucalyptus spp. grown as non-natives in many tropical and sub-tropical countries. this stem canker disease was first reported from south africa and it has subsequently been found on various species and hybrids of eucalyptus in other african countries as well as in countries of south america and south-east asia. in previous studies, phylogenetic analyses based on dna sequence data of the ...	2006	18490975
microsatellite markers for the eucalyptus stem canker fungal pathogen kirramyces gauchensis.	ten microsatellite markers were developed for the fungus kirramyces gauchensis, which causes an important stem canker disease of eucalyptus trees in plantations. primers for 21 microsatellite regions were designed from cloned fragments. fourteen of the primer pairs provided single amplicons and 10 of these were polymorphic for k. gauchensis. allelic diversity ranged from 0.21 to 0.76 with a total of 30 alleles. none of the markers was able to amplify in the phylogenetically distinct but morpholo ...	2008	21585841
