TI  - Physical mapping of the 5S and 45S rDNA in teosintes.
PG  - 16-9
AB  - The physical locations of the 5S and 45S rDNA sequences were examined in three 
      types of teosinte, Zea mays ssp. mexicana (2n = 20), Zea diploperennis (2n = 20) 
      and Zea perennis (2n = 40) by biotinylated fluorescence in situ hybridization 
      (FISH). The tested materials only showed one hybridization site of 5S rDNA on 
      their genomes, but they were different in the position of the signals. The 
      hybridization site of Zea mays ssp. mexicana was located on the long arm of 
      chromosome 2, indicating that it is the same as the cultivated maize in the 
      position of 5S rDNA, while the sites of Zea diploperennis and Zea perennis were 
      on the short arms of other chromosomes. For 45S rDNA, one hybridization site was 
      detected at secondary constriction region of the satellite chromosomes in Zea 
      mays ssp. mexicana and Zea diploperennis, while in Zea perennis, besides the site 
      located at the secondary constriction region, a second site on the short arm of 
      another chromosome pair was observed. Our results provide additional evidence for 
      Zea mays ssp. mexicana being a subspecies of Zea mays.
