  • Gossypium mitochondrial genomes integrated three nuclear retrotransposons and eight chloroplast tRNA genes, and incorporated chloroplast DNA prior to divergence between the diploids and allopolyploid formation. (springer.com)
  • We compared homoeolog (genes duplicated by polyploidy) contributions to the transcriptome of a natural allopolyploid and a synthetic interspecific F1 hybrid, both derived from a merger between diploid species from the Gossypium A-genome and D-genome groups. (nih.gov)
  • Within allopolyploid Gossypium, approximately 24% of the genes with biased (unequal contributions from the two homoeologous copies) expression patterns are inferred to have arisen as a consequence of genomic merger, indicating that a substantial fraction of homoeolog expression biases occur instantaneously with hybridization.

  • In addition, homologs of nearly 1,000 S. cerevisiae ORFs, presently annotated as hypothetical, were found in A. gossypii at syntenic positions and can therefore be considered as authentic genes. (biomedcentral.com)
  • However, 95% of the 4,700 A. gossypii protein-coding genes were found to have a homolog in S. cerevisiae and 90% of these homologous genes map at syntenic positions. (biomedcentral.com)
  • We carried out an extensive search for homology at the amino-acid level between A. gossypii coding regions and S. cerevisiae 'annotation-free' regions: stretches of sequence bearing no annotated genomic features such as ORFs, RNA genes, or transposable elements. (biomedcentral.com)
  • Through allopolyploidization, several modern Gossypium (cotton) species contain two divergent, although largely redundant genomes. (nih.gov)
  • Although, the S. cerevisiae genome is rightly considered as one of the most accurately sequenced and annotated eukaryotic genomes, we have shown that it still benefits substantially from comparison to the completed sequence and syntenic gene map of A. gossypii , an evolutionarily related fungus. (biomedcentral.com)

  • The above studies from Gossypium and other model plant systems highlight the dynamic nature of polyploid genomes and the relatively poorly understood and some times non-Mendelian mechanisms that often characterize gene and genome evolution in polyploids ( 5 , 13 , 24 ). (pnas.org)
