Abstract	Transposable elements (TEs) represent an important fraction of plant genomes and play a significant role in gene and genome evolution. Among all TE superfamilies discovered in plants, Mutator from maize (Zea mays) is the most active and mutagenic element. Mutator-like elements (MULEs) were identified in a wide range of plants. However, only few active MULEs have been reported, and the transposition mechanism of the elements is still poorly understood. In this study, an active MULE named Os3378 was discovered in rice (Oryza sativa) by a combination of computational and experimental approaches. The four newly identified Os3378 elements share more than 98% sequence identity between each other, and all of them encode transposases without any deletion derivatives, indicating their capability of autonomous transposition. Os3378 is present in the rice species with AA genome type but is absent in other non-AA genome species. A new insertion of Os3378 was identified in a rice somaclonal mutant Z418, and the element remained active in the descendants of the mutant for more than ten generations. Both germinal and somatic excision events of Os3378 were observed, and no footprint was detected after excision. Furthermore, the occurrence of somatic excision of Os3378 appeared to be associated with plant developmental stages and tissue types. Taken together, Os3378 is a unique active element in rice, which provides a valuable resource for further studying of transposition mechanism and evolution of MULEs.
