Abstract:
During a survey of gardens in Shiraz County, Iran, aimed at identifying oomycetes associated with roots of ornamental trees, a species of Globisporangium with distinctive morphological characters separating it from other known species in this genus was recovered from conifers and occasionally from a Quercus sp. Five isolates of this species were characterised. Phylogenetic analyses of nuclear (ITS and βtub) and mitochondrial (cox1 and cox2) loci using Bayesian inference and maximum likelihood analyses as well as their distinct morphological and cultural characteristics (e.g., abundant production of chlamydospores; globose, ellipsoid to ovoid sporangia; amorphous oogonia with a smooth wall; paragynous to rarely hypogynous antheridia and 1-5 antheridia per oogonium; mostly plerotic oospores) revealed that these isolates belong to a new Globisporangium species grouping in the phylogenetic clade G of Pythium sensu lato. This paper formally describes Globisporangium coniferarum sp. nov. as a new species and compares it with other phylogenetically related and already known Globisporangium species, including G. nagaii, G. violae, G. paddicum, G. okanoganense, G. iwayamae and G. canariense.
