The predicted ORF has a putative transposase domain and should concern with tranposition of Rice Mutator element. Homology search gives high score to this ORF to say this is a homolog of mudrA gene of maize autonoumous MuDR regulatory element. However, we have not yet know this element is an true autonoumous one or not. At least, this element should be one of derivatives from autonomous element of Rice Mutator.
