Outline of Final Research Achievements	I explored the transposases that contribute to the mobility of long-lived nonautonomous transposons, T2-A1 and T2-C, in the Western clawed frog Xenopus tropicalis. In that process, I created an in silico pipeline to analyze the evolution of transposases, and analyzed the evolution of transposases in X. tropicalis and X. laevis. In addition, I elucidated the dynamics of transposable elements in Xenopus evolution, especially in the allopolyploidization of X. laevis.
