The phenomenon of intercellular migration of nuclei in plant tissues (cytomixis) was discovered over a century ago, which has been followed by numerous attempts to clarify the essence of this process as well as to determine its causes and consequences. Most attention of researchers has been paid to cytomixis in microsporogenesis, since the transfer of part of genetic material between microsporocytes may influence the ploidy level of the produced pollen and, presumably, have an evolutionary significance. This review compiles the data on cytological pattern of cytomixis and proposes a scheme as to how cytomictic channels are formed and function in angiosperms. The prevalence of cytomixis in different plant taxa is analyzed using the published data. The causes, mechanisms, and consequences of the nuclear migration between cells in plant tissues are discussed.
细胞间核迁移现象（胞质杂交）在一个多世纪前就被发现了，此后人们进行了大量尝试来阐明这一过程的本质，以及确定其原因和后果。由于在小孢子发生过程中部分遗传物质的转移可能会影响产生花粉的倍性水平，并可能具有进化意义，因此大多数研究人员都关注胞质杂交。本综述汇总了胞质杂交的细胞学模式数据，并提出了一个关于有花植物中胞质通道形成和功能的方案。利用已发表的数据分析了胞质杂交在不同植物类群中的普遍性。讨论了植物组织中细胞间核迁移的原因、机制和后果。
