| 内容記述 | We observed chromosome behavior during meiosis of Arabidopsis thaliana just after polyploidization. Two strains of A. thaliana, Columbia (Col) and Landsberg erecta (Ler), were treated with colchicine to induce polyploid lines, and the treated generations were analyzed. Flow cytometric analysis revealed that a tetraploid line was obtained from the treated Col and an octoploid line from the treated Ler. Meiotic chromosomes of pollen mother cells of these polyploid lines were visualized by DAPI staining and observed. Both lines underwent meiosis as normal, as did most of the established tetraploid lines on the whole. At metaphase I, however, their numbers of bivalent chromosomes were fewer than expected and chromosome alignment of the octoploid was occasionally disturbed. There was no significant difference between the fertility of diploid and tetraploid, but that of octoploid was significantly reduced, which might be correlated with the disturbance of chromosome configuration. |
