A Nest of LTR Retrotransposons Adjacent the Disease Resistance-Priming Gene NPR1 in Beta vulgaris L. U.S. Hybrid H20

Figure 2

A detailed schematic of Beta vulgaris retrotransposons SCHULTE and SCHMIDT in red. Various numbered inverted repeat (IR) sequences in either light or dark blue or violet have arrows indicating relative direction. Green lines show the location of the DNA sequence motif CACTATAA. Heavily dotted ovular regions depict the size and position of the LTRs. The lightly dotted region shows the size of the whole retroelement. A green box shows the location of the polymerase binding site. Boxes show the position and size of exons. Lines between exons indicate introns. A centrally located small yellow box depicts the active site of the retroelement. An orange box shows the location of the polypurine tract. Scale is in Kb and is located underneath the illustrations in increments of 2 Kb per tick. Names of putative genes are located above the illustrations.
