| Abstract |
Rye chromosome 1R contains many agronomically useful genes. Physical dissection of chromosome 1R into segments would be useful in mapping 1R-specific DNA markers and in assembling DNA clones into contig maps. We applied the gametocidal system to produce rearranged 1R chromosomes of Imperial rye (1R(i)) added to common wheat. We identified rearranged 1R(i) chromosomes and established 55 1R(i) dissection lines of common wheat carrying a single rearranged 1R(i) chromosome. Fifty-two of the rearranged 1R(i) chromosomes had single breakpoints and three had double breakpoints. The 58 breakpoints were distributed in the short arm excluding the satellite (12 breakpoints), in the satellite (4), in the long arm (28), and in the centromere (14). Out of the 55 lines, nine were homozygous for the rearranged 1R(i) chromosomes, and the remaining lines were hemizygous. We developed 26 PCR-based EST markers that were specific to the 1R(i) chromosome, and nine of them amplified 1R(i) arm-specific PCR products without restriction-enzyme digestion. Using the nine EST markers and two previously reported 1R-specific markers, we characterized the 55 1R(i) dissection lines, and also proved that we can select critical progeny plants carrying specific rearranged 1R(i) chromosomes by PCR, without cytological screening, in 48 out of the 55 hemizygous dissection lines. |
