| pcr-based strategy to detect and identify species of phaeoacremonium causing grapevine diseases. | species of phaeoacremonium (especially phaeoacremonium aleophilum) are associated with two severe diseases in grapevines, petri disease in young plants and esca disease in adult plants. phaeoacremonium species grow slowly on culture medium, and it is difficult to identify these species on the basis of morphological characteristics. primers pm1 and pm2 were designed in the ribosomal dna internal transcribed spacer (its) regions its1 and its2, respectively. they yielded a single amplicon of 415 bp ... | 2007 | 17463292 |
| molecular and phenotypic characterisation of novel phaeoacremonium species isolated from esca diseased grapevines. | 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 disea ... | 2008 | 20396582 |
