Abstract:
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. compute-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.
