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
Smallest organisms cetacean, which is also (as of 2006) the most endangered, is the vaquita. Male vaquitas grow to an average of around 135 cm (53 in); the females are slightly longer, averaging about 141 cm (55 in) in length. Duckweeds of the genus "Wolffia" are the world's smallest flowering plants. Fully grown, they measure only 300 µm by 600 µm and reach a mass of just 150 µg. Nanobes are thought by some scientists to be the smallest known organisms about one tenth the size of the smallest known bacteria. Nanobes, tiny filamental structures first found in some rocks and sediments,
