متن کاملOccurrence 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 کاملVariability in morphology and aggressiveness among North American vegetative compatibility groups of Colletotrichum coccodes.
North American isolates of Colletotrichum coccodes, representing six vegetative compatibility groups (NA-VCG), were used to study morphological and pathogenic variability. The objective was to determine if variability in conidial and microsclerotial size was related to pathogenicity. Significant differences were detected in length, width, and length/width ratios of conidia as well as in the len...
متن کاملOnion Routing for Resistance to Traffic Analysis
Using encryption on a packet-switched network can hide the content of messages, much like placing the messages inside a physical envelope. However, by itself encryption does not hide who is talking to whom, and how often. Onion Routing is a general purpose infrastructure for private communication over a widely shared network such as the internet or the SIPRNET. It provides anonymous connections...
