Abstract

Meiotic prophase movement and chromosome bouquet formation are highly conserved processes and essential features of meiosis, yet their functional components and dependencies vary among organisms. A key feature of meiotic prophase is that chromosome regions like telomeres or centromeres become physically tethered to the inner nuclear membrane through a hierarchical and sequential arrangement of proteins. Telomeres or their analogs further interact with the cytoskeletal machinery, which provides the necessary mechanical force to execute the chromosomal movements that enable homologous pairing, synapsis, and meiotic recombination. Despite decades of research, our understanding of these processes, their interdependencies, and their precise role remains incomplete. Here, we summarize the current mechanistic understanding and describe avenues for further exploration.

摘要

减数分裂前期运动和染色体花束形成是高度保守的过程,也是减数分裂的基本特征,但其功能成分和依赖性在不同生物体中有所不同。减数分裂前期的一个关键特征是,端粒或着丝粒等染色体区域通过蛋白质的分层和顺序排列与内核膜物理相连。端粒或其类似物进一步与细胞骨架机制相互作用,细胞骨架机制提供必要的机械力来执行染色体运动,从而实现同源配对、联会和减数分裂重组。尽管经过了数十年的研究,但我们对这些过程、它们的相互依赖性以及它们的确切作用的理解仍然不完整。在这里,我们总结了当前的机制理解,并描述了进一步探索的途径。
