Description | The gene plays an essential role in establishment of homologous chromosome pairing and cytokinesis in male and female meiocytes. The encoded protein contains putative coiled-coil motifs in the middle, two basic regions at both termini, and a potential nuclear localization signal at the C terminus. In the mutant, tagged by the endogenous retrotransposon Tos17, during prophase I all the chromosomes became entangled to form a compact sphere adhered to a nucleolus, and homologous pairing failed to occur. This resulted in complete sterility of male and female gametes. At anaphase I and telophase I, chromosome nondisjunction and degenerated spindle formation resulted in multiple uneven spore production. It is expressed in the early stages of flower development. |
