Definition of syntenic in English:

syntenic

adjectivesɪnˈtɛnɪksinˈtenik
  • (of genes) occurring on the same chromosome.

    syntenic sequences
    Example sentencesExamples
    • A way to diagram this is to color code all the syntenic regions from each chromosome in one organism, and see how those regions are distributed in a second organism.
    • Consider the ancestral genome with all of its chromosomes concatenated and with the ancestral genes blocked by their syntenic groups that will be conserved between the two daughter species.
    • However, the vast majority of duplicated genes are not clustered tandemly, but instead are dispersed in syntenic regions on different chromosomes, most likely as a result of genome-wide duplications and rearrangements.
    • Conserved linkage occurs when two or more homologous genes are syntenic and are in the same order on the chromosome in two or more species.
    • The syntenic genes are displayed as black boxes and linked by lines.

Derivatives

  • synteny

  • noun
    • Because synteny had been previously established, it was possible to evaluate whether homologous genomic regions were involved in regulation of expression of the same genes.
      Example sentencesExamples
      • For each paralogous set with perturbed synteny, it was determined which locus was the ancestral locus of the paralogous set.
      • Mammals also show an extensive conserved synteny of chromosome X, even though translocations have often rearranged the genome of mammalian species.
      • Twenty-six linkage groups were identified and synteny of duplicated microsatellite markers was used to confirm 13 homeologous chromosome pairs.
      • To address this conserved synteny in much more detail, a high-resolution human-chicken comparative map was constructed from human chromosome 15.

Origin

1970s: from syn- 'together' + Greek tainia 'band, ribbon' + -ic.
