Abstract

Clitellate genomes are the result of a profound genome reshaping compared to marine annelids, as if their genomes had exploded into thousands of atomic pieces and were reassembled in a different order by evolution. Recent studies not only revealed widespread gene order shuffling and massive rearrangements but also point to a potential adaptive rationale for this architectural chaos. What triggered such extreme rearrangements, and what molecular logic (if any) underlies their persistence? What is the role of spatial organization and regulatory rewiring in the maintenance of functional integrity in how the genome adjusts to this newly disordered architecture? By synthesizing current discoveries, this review outlines the mechanisms, consequences, and evolutionary paradoxes of genome rearrangement in clitellates, highlighting them as models of extreme yet functional genome plasticity.

绝命毒师:当纤毛虫基因组失控时。
与海洋环节动物相比,纤毛虫的基因组是一次深刻的基因组重塑的结果,就好像它们的基因组爆炸成数千个原子碎片,并在进化过程中以不同的顺序重新组装。最近的研究不仅揭示了广泛的基因顺序洗牌和大规模的重排,而且指出了这种建筑混乱的潜在适应性原理。是什么引发了这种极端的重排,又是什么分子逻辑(如果有的话)支撑着这种重排的持久性?在基因组如何适应这种新的无序结构中,空间组织和调节重新布线在维持功能完整性中的作用是什么?通过综合目前的发现,本文概述了纤毛虫基因组重排的机制、后果和进化悖论,强调了它们是极端但功能性基因组可塑性的模型。

期刊介绍: Launched in 1985, Trends in Genetics swiftly established itself as a "must-read" for geneticists, offering concise, accessible articles covering a spectrum of topics from developmental biology to evolution. This reputation endures, making TiG a cherished resource in the genetic research community. While evolving with the field, the journal now embraces new areas like genomics, epigenetics, and computational genetics, alongside its continued coverage of traditional subjects such as transcriptional regulation, population genetics, and chromosome biology. Despite expanding its scope, the core objective of TiG remains steadfast: to furnish researchers and students with high-quality, innovative reviews, commentaries, and discussions, fostering an appreciation for advances in genetic research. Each issue of TiG presents lively and up-to-date Reviews and Opinions, alongside shorter articles like Science & Society and Spotlight pieces. Invited from leading researchers, Reviews objectively chronicle recent developments, Opinions provide a forum for debate and hypothesis, and shorter articles explore the intersection of genetics with science and policy, as well as emerging ideas in the field. All articles undergo rigorous peer-review.
