| Severe decline of almond trees has recently been observed in several orchards on the island of Mallorca (Balearic Islands, western Mediterranean Sea). However, the identity of the causal agents has not yet been investigated. Between August 2008 and June 2010, wood samples from branches of almond trees showing internal necroses and brown to black vascular streaking were collected in the Llevant region on the island of Mallorca. Several fungal species were subsequently isolated from the margin between healthy and symptomatic tissue. Five species of Botryosphaeriaceae (namely Botryosphaeria dothidea, Diplodia olivarum, D. seriata, Neofusicoccum australe and N. parvum), Eutypa lata, Phaeoacremonium iranianum and Phomopsis amygdali were identified based on... |

| Petri disease and esca are very destructive grapevine decline diseases that occur in most countries where grapevine (Vitis vinifera) is cultivated. Phaeoacremonium species are among the principal hyphomycetes associated with symptoms of the two diseases, producing a range of enzymes and phytotoxic metabolites. The present study compared the phylogeny of a global collection of 118 Phaeoacremonium isolates from grapevines, in order to gain a better understanding of their involvement in Petri disease and esca. Phylogenetic analyses of combined DNA sequence datasets of actin and β-tubulin genes revealed the presence of 13 species of Phaeoacremonium solated from esca diseased grapevines. Phaeoacremonium aleophilum was the most frequently isolated species with... |
