Cuticular Lipids in Plant-microbe Interactions
Cuticle constitutes the boundary between higher plants and their environment. Therefore, this layer might be expected to play an important role in the interaction of the plant with environmental factors. The plant cuticle is composed almost entirely of lipids and the role of some of these lipids in the interaction between plants and microbes has become clear in the recent years. In this brief review, we shall confine our discussion to two specific examples of such interactions: a detrimental one with pathogenic fungi and a beneficial one with phyllospheric bacteria which might provide fixed nitrogen in return for the use of some of the cuticular components as the carbon source. In this context, we will deal only with the role of the insoluble 1ipid-derived polymer, cutin, but not the role of soluble waxes that are always constituents of the cuticle.
