Search of tandem repeats with insertion and deletions in the A. thaliana genome

Abstract

A new mathematical method was used for the first time to search for tandem repeats with insertions and deletions in the full-length sequence of the A. thaliana genome. The method is based on a new algorithm for multiple alignment of sequences of certain periods without using paired comparisons of sequences. We identified 13997 periodic sites 2 to 50 characters long, only approximately 30% of which were known earlier. The possible origin and use of the identified sites with tandem repeats are discussed.
