AB  - In order to analyze the conservation of maize centromeric satellite DNA (CentC) 
      and centromeric retrotransposon (CRM) in the subspecies and relatives of Zea 
      mays, dual fluorescence in situ hybridization (FISH) was used to detect the 
      existence and distribution of the above two repetitive sequences in Zea mays ssp. 
      mexicana, Z. diploperennis, Z. perennis, Tripsacum dactyloides, Coix 
      lacryma-jobi, and Sorghum bicolor. In Z. mays ssp. mexicana, Z. diploperennis, 
      and Z. perennis, both CentC and CRM probes produced strong or relatively strong 
      signals in the centromeric regions of all chromosomes. There was an obvious 
      variation in the intensity of hybridization signals on different chromosomes, 
      indicating that different centromeres have different amounts of CentC and CRM 
      sequences. In some centromeres, the intensity of CentC signals differed from that 
      of CRM signals and was free from overlapping. In T. dactyloides, only weak CentC 
      and CRM signals were detected in the centromeric regions of most chromosomes, 
      while in C. lacryma-jobi and S. bicolor only relatively strong or strong CRM 
      signals primarily located in the centromeric regions were detected. This result 
      indicates that CentC is highly conserved among the subspecies of Z. mays and the 
      species of Zea, and has high conservation in Tripsacum, a genus that is most 
      closely related to Zea, and CRM is conserved among the species of grass family 
      either closely or distantly related to Zea.
