以阿勃小麦为材料,对其减数分裂前期I的细胞学行为和细胞凋亡情况进行了研究,观察到在其减数分裂前期的凝线期存在明显的染色质胞间转移现象,并发现从偶线期到粗线期均存在细胞凋亡现象,而在此前或此后两者均几乎不发生。结合已有的资料分析认为花粉母细胞发育过程中的细胞凋亡尤其是粗线期的细胞凋亡主要是由异常的染色质胞间转移引起的。
Aberdeen wheat was used as a material to study the cytological behavior and apoptosis of pre-meiotic phase I, and it was observed that there was a clear phenomenon of intercellular transfer of chromatin during the pre-meiotic phase of meiosis The phenomenon of apoptosis was found from the even line to the thick line, and hardly occurred either before or after. Combined with existing data analysis that the apoptosis of pollen mother cells during the development of pachytene apoptosis is mainly caused by abnormal intercellular transfer of chromatin.
