Abstract The Mutator (Mu) system of transposable elements is highly mutagenic and can maintain high levels of activity through multiple generations due to frequent transpositions of both its autonomous and nonautonomous components. This family also shows pronounced developmental regulation. Most notable is the very low frequency of germinal reversions, despite the high levels of somatic transpositions and excisions, and the high frequency of germinally transmitted duplication events. Here, we report the production of antibodies raised against MURB, one of two proteins encoded by MuDR, the autonomous regulator of the Mu family. Immunolocalizations performed using anti-MURB antibodies reveal that this protein is present in specific tissues during male inflorescence development. Throughout much of development, MURB is detected at the highest levels in cell lineages that may find themselves in the germ line, but no MURB is detected in microspore mother cells. These cells are the direct precursors to pollen. Based on these observations as well as previous data, we discuss the relationship between the expression of MURB and developmental regulation of Mu activity.
