Mycelial compatibility of 62 isolates of Valsa malicola from different hosts and areas of Iran were investigated on potato dextrose agar (PDA) and oat meal agar (OMA). Four mycelial compatibility groups (MCGs) on PDA, 14, including three single membered (13) and a 58 membered (4) were ...
mali (Yin et al. 2016). However, experimental inoculation tests indicated that it was less virulent on apple than on pear (Wang et al. 2011). Cytospora schulzeri Sacc. & P. Syd. 1899 The telemorph of this species was formerly known as Valsa malicola. This species is commonly found on...
technical support for forecast and prevention of trees Valsa canker.【Method】Based on r DNA-ITS conservative sequence of the Valsa genus,a pair of genus-specific primers and four pairs of species-specific primers were designed for Valsa mali,Valsa sordida,Leucostoma niveum and Valsa malicola....
A real-time quantitative PCR assay using a species-specific primer pair was developed to rapidly and accurately quantifyValsa mali, the causative pathogen of apple Valsa canker (AVC), in crabapple seeds, crabapple seedlings, apple twigs and apple seeds. Surveys were conducted in different regions, ...
The telemorph of this species was formerly known asValsa malicola. This species is commonly found on dead or dying twigs ofMalusspecies in Asia, Europe, North America and South Africa (Hayova and Minter1998a; Adams et al.2005). It has been associated with dieback of twigs, with symptoms...
malicola indicates the eligibility of the marker to investigate ranks below the species level. The results of cluster analysis indicated that isolates are related to each other with 45.63% similarity and four groups (1, 2, 3 and 4) were identified in the dendrogram. Group 3 included 37 ...
Genetic diversity of 40 isolates of Valsa malicola in Iran was investigated by MP-PCR. Isolates were obtained from different host plants in diverse regions during 2004-2010. Of the six microsatellite primers tested, only four primers; (ACTG)(4), (GACA)(4), (AC)(8) and (CGA)(5,) ...

Here, we report genome assemblies of Valsa malicola, Valsa persoonii, and Valsa sordida which represent close relatives of Valsa mali and Valsa pyri with different host preferences. Comparative genomics analysis revealed that segmental rearrangements, inversions, and transloca...
Valsa malicolaValsa canker is a destructive disease on apple that causes serious economic losses in eastern Asia. In the present study fungal isolates from cankered apple and pear bark were examined and compared with morphology and rDNA-ITS sequences. Valsa mali was confirmed to be an ...
