| Outline of Final Research Achievements |
During meiosis in interspecific hybrids of T. fournieri (2n=2x=18) x T. baillonii (2n=2x=16), eight bivalents by interspecific pairing and a univalent of T. fournieri chromosome were observed, Phylogenetic analysis suggests a hypothesis that T. baillonii lost the chromosome during the speciation. In order to verily the hypothesis, comparative genome analysis of T. fournieri and T. baillonii was conducted. The results indicated that T. baillonii genomic DNAs can find on all nine of T. fournieri chromosomes and the loss of a chromosome pair might be not true during the speciation.
