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
Ferric uptake regulator family Ferric uptake regulator family In molecular biology, the ferric uptake regulator family is a family of bacterial proteins involved in regulating metal ion uptake and in metal homeostasis. The family is named for its founding member, known as the ferric uptake regulator or ferric uptake regulatory protein (Fur). Fur proteins are responsible for controlling the intracellular concentration of iron in many bacteria. Iron is essential for most organisms, but its concentration must be carefully managed over a wide range of environmental conditions; high concentrations can be toxic due to the formation of reactive oxygen species.
