Synthesized allopolyploids are valuable materials for comparative analyses of two or more distinct genomes, such as the expression changes (activation, inactivation or differential expression) of orthologous genes following allopolyploidization. CENH3 is a centromere- specific histone H3 variant and has been regarded as a central component in kinetochore formation and centromere function. In this study, interspecific hybrids of Oryza genus (AA × CC, AA × CCDD) and their backcross progenies were produced, and the genome constitutions were identified as AC, ACC, ACD, AACD, or AA(CD) by Genomic in situ hybridization (GISH)...
