RESites corresponding to mined Arabidopsis elements. (A) Examples of RESites for different groups of mined elements. All of the RESites illustrated were identified by computer-assisted database searches. In total, 34 RESites were found by computer-assisted database searches, and 13 were identified by cross-ecotype PCR analysis. The target sequences are underlined, and the TSDs are shaded. GenBank geninfo identifier (gi) numbers and nucleotide position on clones are indicated. *, Inserted into a Basho III element; †, inserted into a Basho III element; ‡, inserted into a MITE IX element. (B) RESites found for Basho insertions confirm mononucleotide TSD (shaded). §, Inserted into a Basho V element.
