A review of several microinstabilities have been suggested as possible anomalous transport mechanisms in current sheets is presented. The specific application is to a field reversed plasma which is relevant to the so-called diffusion region of a reconnection process. The linear and nonlinear properties of the modes are discussed, and each mode is assessed as to its importance in reconnection processes based upon these properties. It is concluded that the two most relevant instabilities are the ion acoustic instability and the lower-hybrid-drift instability. However, each instability has limitations as far as reconnection is concerned, and more research is needed in this area. Author
