Bamboo mosaic virus before that. The natural host of this virus is bamboo. It is known to infect at least 12 different species in 7 different genera. In host range studies it has been shown to cause local lesions on "Chenopodium amaraticolor" and "Gomphrena globosa" and a systemic infection in barley ("Hordeum vulgare"), another member of the grass family, "Poaceae" or "Gramineae". Symptoms in bamboo include chlorotic mottling/mosaic patterns on the leaves which run parallel with the veins (Typical symptoms on leaves), necrotic streaking on the shoots and stem abortion. However, not all susceptible plants show recognizable symptoms. Bamboo mosaic virus "Bamboo mosaic
Detection of genetically modified organisms GMOs. In 2012, 12% of the samples analysed contained detectable amounts of GMOs (including 2.4% of GMOs forbidden in Switzerland). Except one, all the samples tested contained less than 0.9% of GMOs; which is the threshold that impose labelling indacating the presence of GMOs. Detection of genetically modified organisms The detection of genetically modified organisms in food or feed is possible by biochemical means. It can either be qualitative, showing which genetically modified organism (GMO) is present, or quantitative, measuring in which amount a certain GMO is present. Being able to detect a GMO is an important part of GMO
