TI  - A New Nomenclature of Xenopus laevis Chromosomes Based on the Phylogenetic 
      Relationship to Silurana/Xenopus tropicalis.

AB  - Xenopus laevis (XLA) is an allotetraploid species which appears to have undergone 
      whole-genome duplication after the interspecific hybridization of 2 diploid 
      species closely related to Silurana/Xenopus tropicalis (XTR). Previous cDNA 
      fluorescence in situ hybridization (FISH) experiments have identified 9 sets of 
      homoeologous chromosomes in X. laevis, in which 8 sets correspond to chromosomes 
      1-8 of X. tropicalis (XTR1-XTR8), and the last set corresponds to a fusion of 
      XTR9 and XTR10. In addition, recent X. laevis genome sequencing and BAC-FISH 
      experiments support this physiological relationship and show no gross chromosome 
      translocation in the X. laevis karyotype. Therefore, for the benefit of both 
      comparative cytogenetics and genome research, we here propose a new chromosome 
      nomenclature for X. laevis based on the phylogenetic relationship and chromosome 
      length, i.e. XLA1L, XLA1S, XLA2L, XLA2S, and so on, in which the numbering of XLA 
      chromosomes corresponds to that in X. tropicalis and the postfixes 'L' and 'S' 
      stand for 'long' and 'short' chromosomes in the homoeologous pairs, which can be 
      distinguished cytologically by their relative size. The last chromosome set is 
      named XLA9L and XLA9S, in which XLA9 corresponds to both XTR9 and XTR10, and 
      hence, to emphasize the phylogenetic relationship to X. tropicalis, XLA9_10L and 
      XLA9_10S are also used as synonyms.
