FlyBase curator comment: TI{TI} represents DNA inserted into the genome via any technique (such as homologous recombination or other targeted mutagenesis) which results in the inserted DNA not being flanked by transposable element ends. The precise sequence inserted may differ for different insertions of the construct. For details of what is inserted into the genome for an individual insertion of TI{TI}, see the description in the insertion report and in any allele reports associated with that insertion.
