Abstract
Plant lipids have an important role in plant life processes, such as membrane component, energy source in seeds, signal molecular in stress response, and anti-fungal/bacterial compounds in defense response. A specific organelle, oil body, stores plant lipids. Oil bodies are accumulated in seeds, anthors and stressed leaves. Leaf-oil bodies are located in cytosol, in contrast to plastoglobules in plastid. Leaf-oil bodies are increased in the number by senescence and various stresses including fungal infection. Colletotrichum higginsianum is a hemibiotrophic fungal pathogen and causes anthracnose disease on Arabidopsis thaliana and other crucifer hosts. Interestingly, Colletotrichum higginsianum infection induced a leaf-oil-body related protein around the fungal lesion. The leaf-oil-body related protein might contribute to defense response against Colletotrichum higginsianum infection. We suppose that leaf-oil bodies and the leaf-oil-body related protein inhibit fungal spread.
