Abstract

 A foxtail millet-rice comparative genetic map was constructed using mapped rice RFLP markers and wheat genomic and cDNA clones with known map position in rice. About 74% and 37% of the cDNA and genomic clones, respectively, were transferable to foxtail millet, confirming that conservation at the DNA level is greatest in genic regions. A high degree of conserved colinearity was observed between the two genomes. Five entire foxtail millet chromosomes appear to be colinear with five entire rice chromosomes. The remaining four foxtail millet linkage groups each show colinearity with segments of two rice chromosomes. The rearrangements of rice chromosomes 3 and 10 to form foxtail millet chromosome IX, and 7 and 9 to form chromosome II are very similar to those required to form maize chromosomes 1 and 7 and sorghum linkage groups C and B, indicating Setaria’s clear taxonomic position within the subfamily of the Panicoideae.
