A middle repetitive sequence NPR18 was isolated from Nicotiana plumbaginifolia nuclear genome [8]. Sequences homologous to the repeat are dispersed through genomes of several Nicotiana species. Computer-assisted data analysis of NPR18 primary sequence reveals several features attributed to mobile genetic elements: an AT content higher than average for nuclear DNA of genus Nicotiana plants; a number of direct and inverted repeats. Some of the repeats displayed homology to the terminal and subterminal repeats of Ac/Ds-like plant elements.
从烟草（Nicotiana plumbaginifolia）核基因组中分离出一个中等重复序列NPR18[8]。与该重复序列同源的序列分散在几个烟草物种的基因组中。对NPR18一级序列进行计算机辅助数据分析，揭示了一些可归因于移动遗传元件的特征：AT含量高于烟草属植物核DNA的平均水平；存在一些正向和反向重复序列。其中一些重复序列与Ac/Ds类植物元件的末端和亚末端重复序列具有同源性。
