The ITS1 and ITS2 regions of rDNA were similar among populations of G. rostochiensis and

differed in 1–3% of 1000-bp sequence. The analysis of populations polymorphism based on the RAPD technique also showed differences among populations of G. rostochiensis, indicating that climatic conditions of the mountainous area might have influence on genetic variability. “
“In 2012, dark brown spots were BVD-523 solubility dmso observed on leaves of Ledebouriella seseloides (Fang Feng) in several research plots located at the Goseong Agricultural Research Extension services in Gyeongam Province, Republic of Korea. A fungus was isolated from the infected plants which produced pink-coloured spores in mucilage on PDA and conidial morphology suggested that the causal

agent was Colletotrichum gloeosporioides. Internal transcribed spacer sequences of the pathogen showed 99% identity to those of C. gloeosporioides. Pathogenicity of the isolate was proved by Koch’s postulates. This is the first report of anthracnose in L. seseloides caused by Aurora Kinase inhibitor C. gloeosporioides. “
“Some lignivorous hymenomycete fungi are capable of causing both cankers and decay in stemwood of adult trees. Recently in Tuscany (Italy), Platanus x acerifolia trees were found colonized by Sarcodontia pachydon (Polyporales, Meruliaceae), a fungus associated with white rot and stem cankers on different host tree species. Because the relationship S. pachyodon-plane-tree was only preliminary studied, we decided to investigate whether isolates obtained from this host are distinct from those commonly collected from oaks. For this purpose, isolates obtained from plane-tree and from holm oak (Quercus ilex) were compared by in vitro test and molecular markers. Results showed that fungal isolates did not differ in growth nor in wood degradation, also molecular tests revealed Lonafarnib ic50 relative similarity among fungal samples. “
“A stem blight disease was observed on the lower portions of Brassica juncea stems during the cropping season (2010–2011). In advanced stages, the lesions were up to 120 cm in length on the stems and also spread to petioles

and midribs of leaves. The purified fungus was identified as Nigrospora oryzae (Berk. & Br.) Petch (teleomorph Khuskia oryzae), which produced similar symptoms when healthy B. juncea plants were inoculated, thus proving Koch’s postulates. This is the first report of the occurrence of N. oryzae on B. juncea. “
“Aster yellows phytoplasma was detected for the first time in goldenrain tree (Koelreuteria paniculata) growing in Sinpyeong-myeon, Jeollabuk-do, South Korea. DNA was extracted from the infected leaf samples and part of the 16S rDNA, rp operon and tuf gene were amplified using R16F2n/R2 and gene-specific primers. The sequence analysis showed that the phytoplasma was closely related (99%) to members of the Aster Yellows (AY) group, and belonging to 16Sr I, subgroup B.
