| Comparative analysis of nucleotide sequences of the genomic region located around 100 map unit of chromosome 1 using two accessions, Columbia (Col) and Landsberg erecta (Ler), of Arabidopsis thaliana was performed. High divergence was detected between them, and the length of the Ler sequence was half of corresponding sequence of Col. This divergence occurred by tandem duplication, deletion of large regions, and insertion of unrelated sequences. These events led to the high polymorphism of plant disease resistant genes, which are located in the analyzed region. It is highly probable that two-round duplication occurred, and the insertion sequences are transposable elements. The data suggest that the analyzed region had been evolving until quite recently. |
