Coe1 in Beta vulgaris L. Has a Tnp2-Domain DNA Transposase Gene within Putative LTRs and Other Retroelement-Like Features

Figure 5

A schematic diagram of an Arabidopsis Coe1-like composite Class II transposon within a Class I LTR-retrotransposon. A central gene colored blue encodes a CACTA-superfamily transposase between retrotransposon genes colored red, all within retrotransposon LTRs. Light green lines depict the DNA sequence motif CACTA. Heavily dotted regions show LTRs. The lightly and darkly red and blue dotted box regions show the composite. A red box with downward (backward) slanting lines shows a RNA polymerase binding site (PBS). Darker red or blue boxes show exons. Dark red retrotransposon ORFs (dark) are interrupted by lighter red introns. A central DNA transposase gene is dark blue with light blue introns. A red box with upward (forward) slanting lines is a polypurine tract. Scale is in kilobases located below has 2 Kb increments. Names assigned putative genes are above their representations.
