TI  - Microsatellite megatracts in the maize (Zea mays L.) genome.
PG  - 1061-9
AB  - Long tracts (megatracts) of (CAG)n, (TAG)n, and (GAA)n microsatellite sequences 
      capable of forming composite DNA segments were found in the maize (Zea mays L.) 
      genome. Some of the (CAG)n and (TAG)n megatracts were organized in clusters of up 
      to 1 Mb on several chromosomes, as detected by fluorescence in situ hybridization 
      (FISH), as well as on extended DNA fibers. Extensive polymorphism was found among 
      different maize inbred lines with respect to the number and size of 
      microsatellite megatract clusters on the A chromosomes. Polymorphism was also 
      common among B chromosomes of different nuclei in the inbred line Zapalote Chico. 
      Different retrotransposable elements were often inserted into the microsatellite 
      tracts. Size variation in some (TAG)n and (GAA)n megatracts was observed in 
      consecutive generations among siblings of the inbred lines, indicating that these 
      loci are highly unstable and predisposed to dynamic mutations similar to those 
      described in mammalian systems.
