We have characterised a new family of repetitive sequences that we have named Mrs (maize repetitive sequences). Mrs elements are associated with different maize genes and seem to be specific for the genome of Zea species. Mrs elements are short, AT-rich and contain terminal inverted repeats (TIRs). The sequence of their TIRs, as well as the fact that they are flanked by short repetitions that tend to be TAA, allows us to propose Mrs as a new subfamily of Tourist transposable elements.

Tourist was originally described as a 128-bp insertion mutation in the maize wx-B2 allele. Subsequent analysis revealed that Tourist elements are in the introns or flanking sequences of 11 maize genes and a single barley gene. In this study we report that Tourist elements are frequently associated with the wild-type genes of two other grasses, rice and sorghum.
