| two new species of botryosphaeria with brown, 1-septate ascospores and dothiorella anamorphs. | botryosphaeria sarmentorum sp. nov. and b. iberica sp. nov. are described and illustrated. these two species are unusual in this genus because of their brown, 1-septate ascospores. phylogenetic analysis based on its and ef1-alpha sequences place them within the clade containing species with fusicoccum anamorphs. the brown, 1-septate conidia, however, do not conform to fusicoccum. therefore phylogenetically and morphologically the anamorphs of these two species belong in a genus distinct from any ... | 2005 | 16396358 |
| dna phylogeny, morphology and pathogenicity of botryosphaeria species on grapevines. | several species of botr yosphaeria are known to occur on grapevines, causing a wide range of disorders including bud mortality, dieback, brown wood streaking and bunch rot. in this study the 11 botryosphaeria spp. associated with grapevines growing in various parts of the world, but primarily in south africa, are distinguished based on morphology, dna sequences (its-1, 5.8s, its-2 and ef1-α) and pathological data. botryosphaeria australis, b. lutea, b. obtusa, b. parva, b. rhodina and a diplodia ... | 2004 | 21148899 |
