Real-time PCR detection of Phaeomoniella chlamydospora and Phaeoacremonium aleophilum.
Phaeomoniella chlamydospora and Phaeoacremonium aleophilum are the two main fungal causal agents of Petri disease and esca. Both diseases cause significant economic losses to viticulturalists. Since no curative control measures are known, proactive defensive measures must be taken. An important aspect of current research is the development of sensitive and time-saving protocols for the detectio...
متن کاملXylem Vessel Diameter Affects the Compartmentalization of the Vascular Pathogen Phaeomoniella chlamydospora in Grapevine
Fungal wilt diseases are a threat to global food safety. Previous studies in perennial crops showed that xylem vessel diameter affects disease susceptibility. We tested the hypothesis that xylem vessel diameter impacts occlusion processes and pathogen compartmentalization in Vitis vinifera L. We studied the interaction between four grape commercial cultivars with the vascular wilt pathogen Phae...
متن کاملDevelopment of an isolate-specific marker for tracking Phaeomoniella chlamydospora infection in grapevines.
Petri disease causes decline of grapevines worldwide. The grapevine endophyte Phaeomoniella chlamydospora is the most important fungal pathogen associated with this disease. Epidemiological studies of this pathogen have been hampered by its common occurrence in the internal tissue of apparently healthy vines. Development of a molecular marker for a single strain would overcome this limitation a...
متن کاملDraft Genome Sequence of Phaeomoniella chlamydospora Strain RR-HG1, a Grapevine Trunk Disease (Esca)-Related Member of the Ascomycota
The Ascomycota species Phaeomoniella chlamydospora, in concert with other fungi, is a causal agent for grapevine trunk diseases. Here, we present the first draft of the P. chlamydospora genome sequence, which comprises 355 scaffolds, with a total length of 26.59 Mb and 7,279 predicted protein-coding genes.
متن کاملVariations in Early Response of Grapevine Wood Depending on Wound and Inoculation Combinations with Phaeoacremonium aleophilum and Phaeomoniella chlamydospora
Defense mechanisms in woody tissue are poorly understood, especially in vine colonized by trunk pathogens. However, several investigations suggest that molecular mechanisms in the central tissue of Vitis vinifera L. may be involved in trunk-defense reactions. In this work, the perception of Phaeoacremonium aleophilum and Phaeomoniella chlamydospora alone or together were investigated in cutting...
