Atspoll-2 mutant was used with other meiotic mutants to examine the regulatory system of centromere roles during meiosis in this research. Yeast and Arabidopsis centromeres have been shown to couple with each other at early prophase I to promote homolog pairing, and to direct the polarity of sister chromatids at metaphase I. The present research revealed that centromere coupling at early prophase I was independent of meiotic homologous recombination, but that the decision of sister centromere polarity was dependent on recombination.}, pages = {61--69}, title = {シロイヌナズナの生殖過程に異常のある変異体の染色体解析II}, volume = {18}, year = {2007} }
