Meiosis I spindle formation can be partially rescued in <i>trem^F9</i> by X-ray treatment.

aA lemon shaped spindle is the characteristic shape of a metaphase I spindle [24]. The average spindle length was 8.32 µm for wild type, 7.98 µm for tremF9 (no X-ray), and 9.18 µm for tremF9 (X-ray). bThe average spindle length for a prometaphase spindle was 19 µm for wild type, 18.02 µm for tremF9 (no X-ray), and 17.04 for tremF9 (X-ray). cTotal number of prometaphase and metaphase figures analyzed. dtremF9 single spindles did not necessarily display the proper chromosome configuration.a 减数分裂I中期纺锤体（metaphase I spindle）的典型形态为柠檬形纺锤体[24]。野生型样本的纺锤体平均长度为8.32 μm，未接受X射线照射的tremF9组为7.98 μm，接受X射线照射的tremF9组为9.18 μm。 b 前中期纺锤体的平均长度：野生型为19 μm，未接受X射线照射的tremF9组为18.02 μm，接受X射线照射的tremF9组为17.04 μm。 c 本次分析所纳入的前中期与中期分裂相总数。 d tremF9突变株的单个纺锤体未必呈现正常的染色体构型。
