图6 绿豆雄性不育突变体msm2015-1花粉早期发育阶段分析 A: 花粉早期发育的各个时期, 白色箭头指示msm2015-1四分体时期的不对称和不均等分裂导致形成的大小不一的小孢子; B: 四分体时期出现的异常多分裂, 图中数字表示msm2015-1分裂出的小孢子个数。PMC: 花粉母细胞; Tetrad: 四分体; Msp: 小孢子; Pollen: 花粉。图中标尺为20 µm。

Fig. 6 Developmental early stage analysis of msm2015-1’s pollen in mungbean A: the early stages of pollen development, the white arrows indicate the uneven-size microspores caused by the asymmetry and inhomogeneity meiosis during the tetrad stage; B: the anomalous more fission of meiosis happened during the tetrad stage, the numbers of msm2015-1’s microspores are indicated by the Arabic numbers. PMC: pollen mother cell; Msp: microspore. Bar = 20 µm.
