Sequence Organization on Two BACs from the rp1 Complex.

The four Rp1 homologs were named rp1-1 through rp1-4. Arrows indicate genes and arrowheads indicate truncated genes, plus their size and proposed direction of transcription. Asterisks indicate simple sequence repeats (SSRs) that contain eight or more tandem repeats. Lines connecting the two BACs indicate the 43-kb duplicated region. Grande, Ji, Opie, and PREM-1 are maize retrotransposons. Miniature inverted repeat transposable elements (MITEs) are indicated by small triangles. The two large arrowheads indicate inverted repeat sequences of 2283 and 2284 bp that are 96% identical to each other (ignoring indels) and separated by 199 bp.
