| Research Abstract |
We have isolated Arabidopsis orthologs, constans (CO) and flowering locus T (FT) genes from Japanese beech tree, which are mainly function in flower transition, and their full sequences were identified. Real-Time PCR analysis revealed that CO transcripts are closely related to flowering initiation with high expression level of CO mRNAs during the period in May, a year before flowering. Transgenic Arabidopsis overexpressing CO product represented early flowering phenotype, this is a result of revealing its flowering enhancement function of CO. Their comparisons of nucleotide sequences were performed among 38 clones collected from Tohoku area. It seemed likely that there are possibilities of insertion/deletion including nucleotide polymorphisms (SNPs) within several FT genes that might influence its function, while there are no differences among CO sequences. Further analyses of FT including SNPs and producing overexpressing lines are ongoing.
