Diversity of long terminal repeat retrotransposon genome distribution in natural populations of the wild diploid wheat Aegilops speltoides.

ABSTRACT: The environment can have a decisive influence on the structure of the genome, changing it in a certain direction. Therefore, the genomic distribution of environmentally sensitive transposable elements may vary measurably across a species area. In the present research, we aimed to detect and evaluate the level of LTR retrotransposon intraspecific variability in Aegilops speltoides (2n = 2x = 14), a wild cross-pollinated relative of cultivated wheat. The interretrotransposon amplified polymorphism (IRAP) protocol was applied to detect and evaluate the level of retrotransposon intraspecific variability in Ae. speltoides and closely related species. IRAP analysis revealed significant diversity in TE distribution. Various genotypes from the 13 explored populations significantly differ with resp
