This review summarizes the published data on their identification, taxonomy, ecology, modes of action and biocontrol efficacy, and the results obtained with the two products already registered, AQ10 Biofungicide and Sporodex are discussed.
Identification of two powdery mildew fungi, Oidium neolycopersici sp. nov. and O. lycopersici, infecting tomato in different parts of the world
A phylogenetic analysis of the internal transcribed spacer sequences of the ribosomal DNA (rDNA) indicated that O. neolycopersici is closely related to Erysiphe macleayae, E. aquilegiae and other Pseudoidium species.
Dual Roles of Reactive Oxygen Species and NADPH Oxidase RBOHD in an Arabidopsis-Alternaria Pathosystem1[W]
It is proposed that functional RBOHD triggers death in cells that are damaged by fungal infection but simultaneously inhibits death in neighboring cells through the suppression of free salicylic acid and ethylene levels.
Nuclear and Chloroplast Microsatellites Show Multiple Introductions in the Worldwide Invasion History of Common Ragweed, Ambrosia artemisiifolia
The results indicate that the expansion in Europe mostly occurred through long-distance dispersal, explaining the absence of isolation by distance and the weak influence of geography on the genetic structure in this area in contrast to the native range.
Biology and biocontrol potential of Ampelomyces mycoparasites, natural antagonists of powdery mildew fungi
Ampelomyces mycoparasites have now become one of the most advanced in terms of commercial development of a fungal biocontrol agent, although there is still a need for more development work to produce a product with reliability approaching that of conventional chemical treatments.
First comprehensive phylogenetic analysis of the genus Erysiphe (Erysiphales, Erysiphaceae) I. The Microsphaera lineage
A comprehensive phylogenetic analysis of the Microsphaera-lineage, a monophyletic group including species of sects, supports the previous hypothesis that tree-parasitic powdery mildews are phylogenetically primitive in the Erysiphaceae in general, and host-shift from trees to herbs occurred many times independently during the evolution of powderY mildews.
First comprehensive phylogenetic analysis of the genus Erysiphe (Erysiphales, Erysiphaceae) II: the Uncinula lineage
Molecular clock analysis suggests that the major seven clades appeared 50–30 million years ago (Ma) in the Paleogene Period, and the Microsphaera lineage may have split from the Uncinula lineage at the boundary of the Paleocene and Neogene, when appendages with dichotomously branched tips appeared.
Distinct invasion sources of common ragweed (Ambrosia artemisiifolia) in Eastern and Western Europe
It is found that A. artemisiifolia from Eastern Europe did not originate from the earlier established French populations but rather represents multiple independent introductions from other sources, or Introductions from a not yet identified highly diverse native population.
Early distribution and spread of Ambrosia artemisiifolia in Central and Eastern Europe
The herbarium records back-date the first known introduction of this noxious weed to Central and Eastern Europe as well as its early spread on the Danube-Tisza Plain, and in the North-Eastern part of Hungary.
