Occurrence of Anthracnose on Welsh Onion Caused by Colletotrichum circinans
Anthracnose occurred frequently on leaf sheaths of Welsh onions grown in Gangwha island, Korea in November, 2007. The disease incidence was as high as 30% in five fields investigated. A total of 20 single spore isolates of Colletotrichum species were obtained from the affected plants, and all the isolates were identified as Colletotrichum circinans based on their morphological and cultural char...
متن کاملGenetic Variability in the Potato Pathogen Colletotrichum coccodes as Determined by Amplified Fragment Length Polymorphism and Vegetative Compatibility Group Analyses.
ABSTRACT Amplified fragment length polymorphism (AFLP) using three primer sets was used to characterize 211 Colletotrichum coccodes isolates from North America, 112 of which were assigned to six vegetative compatibility groups (VCGs) using nitrate nonutilizing (nit) mutants. These isolates clustered into five corresponding groups by unweighted pairgroup method with arithmetic means-based cluste...
متن کاملCan denaturing gradient gel electrophoresis (DGGE) analysis of amplified 16s rDNA of soil bacterial populations be used in forensic investigations?
In criminal investigations, information on the origin of soils may be crucial for solving cases. The biological complexity of soil may potentially be used for sorting and differentiating between soil samples. Nucleic-acid based analyses of soil microbial populations are powerful tools, routinely used in studies of this habitat. Application of such approaches in forensics implies that a standard...

متن کاملColletotrichum Circinans as a Semiquantitative Test Unit for the Growth Substance Produced by Rhizopus Suinus.
COLLETOTRICHUM CIRCINANS AS A SEMIQUANTITATIVE TEST UNIT FOR THE GROWTH SUBSTANCE PRODUCED BY RHIZOPUS SUINUS WHILE testing the filtrate of Rhizopus suinus Nielson on the growth of various species of fungi, it was noted that Colletotrichum circinans (Berk.) Vogl. gave consistent increments in yield over a limited range of concentrations. This characteristic response of the organism mentioned su...
