Some dispersed repeated sequences and their flanking regions from wheat and maize ctDNAs have been characterized. Two sets of wheat ctDNA repeats were found to be the chloroplast ribosomal protein genesrpl2 andrpl23, plus nonfunctional segments of them, designatedrpl2′ andrpl23′. Pairwise comparisons were made between the wheatrp123 andrpl23′, and the maizerp123′ sequences. The precise patterns of homology suggest that the divergence of the wheat and maize nonfunctional (rpl23′) sequences is… CONTINUE READING
