Organization of retro-element and stem-loop repeat families in the genomes and nuclei of cereals.
Sequences homologous to the retro-element BIS-1 and the stem-loop repeat Hi-10 are present in the genomes of a number of cereal species. A detailed characterization of these elements indicated that they are non-randomly organized in the genomes of at least two of these species, namely barley and rye. In contrast to the BIS-1 retro-elements, the stem-loop repeats are also non-randomly organized into discrete domains in interphase nuclei from barley and rye. Features of the organization of these repeats along chromosomes and within interphase nuclei of rye, barley and rice are discussed.
