Abstract

When diverse lineages repeatedly adapt to similar environmental challenges, the extent to which the same genes are involved (gene reuse) varies across systems. We propose that divergence time among lineages is a key factor driving this variability: as lineages diverge, the extent of gene reuse should decrease due to reductions in allele sharing, functional differentiation among genes, and restructuring of genome architecture. Indeed, we show that many genomic studies of repeated adaptation find that more recently diverged lineages exhibit higher gene reuse during repeated adaptation, but the relationship becomes less clear at older divergence time scales. Thus, future research should explore the factors shaping gene reuse and their interplay across broad divergence time scales for a deeper understanding of evolutionary repeatability.

分歧时间决定了重复适应过程中的基因再利用。
当不同的品系反复适应类似的环境挑战时,相同基因参与的程度(基因重复使用)在不同的系统中会有所不同。我们认为,种系间的分化时间是导致这种变异的关键因素:随着种系的分化,等位基因共享的减少、基因间的功能分化以及基因组结构的重组,基因重复使用的程度应该会降低。事实上,我们的研究表明,许多关于重复适应的基因组研究发现,在重复适应过程中,较新分化的世系表现出较高的基因重复使用程度,但在较早分化的时间尺度上,这种关系就不那么明显了。因此,未来的研究应该探索影响基因重复使用的因素及其在广泛的分化时间尺度上的相互作用,以加深对进化重复性的理解。

期刊介绍: Trends in Ecology & Evolution (TREE) is a comprehensive journal featuring polished, concise, and readable reviews, opinions, and letters in all areas of ecology and evolutionary science. Catering to researchers, lecturers, teachers, field workers, and students, it serves as a valuable source of information. The journal keeps scientists informed about new developments and ideas across the spectrum of ecology and evolutionary biology, spanning from pure to applied and molecular to global perspectives. In the face of global environmental change, Trends in Ecology & Evolution plays a crucial role in covering all significant issues concerning organisms and their environments, making it a major forum for life scientists.
