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

Figure 3

Amino acid residue alignment of SCHULTE’s integrase (top) and reverse transcriptase (bottom) domains. The active site of the RT domain from Beta vulgaris is boxed in along with corresponding sections of other reverse transcriptase proteins from different plants. Amino acids matching the consensus sequence are shaded. Numbers indicate cumulative amino acid positions; Arabidopsis thaliana (AAG50698), Beta vulgaris (ABM55238), Glycine max (AAO73521), Medicago truncatula (ABD32582), Oryza sativa japonica (AAR87335), Phaseolus vulgaris (AAR13298), Solanum demissum (AAT38797), Vitis vinifera (CAN74951), Zea mays (ABF67921).
