多倍体是由基因组复制引起的，在真核生物的整个历史中都有发生，尽管它在植物中特别常见。由此产生的基因组的大小、杂合性和复杂性的增加可能是一个进化的机会，促进多样化、适应性和功能新颖性的进化。另一方面，当多倍体首次出现时，它们面临着许多挑战，其中最大的挑战之一是减数分裂配对、重组和分离，每条染色体突然超过两个拷贝，这可能会限制它们的生育能力。为了开发多倍体作为作物改良工具（由于多倍体具有高度和持久的多逆境适应能力，多倍体具有很大的前景），以及为了我们对减数分裂和植物进化的基本理解，我们需要知道多倍体面临挑战的具体性质，以及如何在进化中克服它们。近年来，我们对多倍体适应减数分裂挑战的分子基础的理解有了显著的提高，这是本综述的重点。
Polyploidy, which arises from genome duplication, has occurred throughout the history of eukaryotes, though it is especially common in plants. The resulting increased size, heterozygosity, and complexity of the genome can be an evolutionary opportunity, facilitating diversification, adaptation and the evolution of functional novelty. On the other hand, when they first arise, polyploids face a number of challenges, one of the biggest being the meiotic pairing, recombination and segregation of the suddenly more than two copies of each chromosome, which can limit their fertility. Both for developing polyploidy as a crop improvement tool (which holds great promise due to the high and lasting multi-stress resilience of polyploids), as well as for our basic understanding of meiosis and plant evolution, we need to know both the specific nature of the challenges polyploids face, as well as how they can be overcome in evolution. In recent years there has been a dramatic uptick in our understanding of the molecular basis of polyploid adaptations to meiotic challenges, and that is the focus of this review.
