Mobile inverted-repeat elements of the Tourist familyare associated with the genes of many cereal grasses.
Open accessAbstract
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. Six of 35 rice and 5 of 8 sorghum complete gene sequences reported to date contain Tourist elements. Furthermore, 11 additional maize genes have been found to contain Tourist elements, bringing the current total of elements associated with maize genes to 23. Sequence comparison of Tourist elements has led to the identification of four subfamilies, designated A-D. Evidence is presented for the recent mobility of elements in three of these subfamilies and in three of the four grass species. These data suggest that Tourist elements are highly repetitive in the genomes of some and perhaps all members of the grasses.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
