摘要
植物物种形成和多样化过程中,多倍化发挥着重要作用,它汇聚了新的等位基因,产生了多倍体.自然界中有许多重要作物是多倍体,相关研究发现,与二倍体植物相比,多倍体具有更强的抗逆性,能够适应更广泛的生态环境.本文简要介绍了植物多倍化及其影响,并总结了近几年来多倍体植物基因组组装、起源与演化、三维基因组和甲基化修饰的最新研究进展,同时就多倍体端粒到端粒(T2T)基因组、图泛基因组等进行了讨论和展望.
Abstract
Polyploidization plays a crucial role in the formation and diversification of plant species,facilitating the accumulation of novel alleles and the emergence of polyploids.Many important agricultural crops are polyploids,and research suggests that they ex-hibit enhanced stress resistance and adaptability to diverse ecological environments compared to diploid plants.This article provides an overview of plant polyploidization and its implications,summarizing recent advancements in various aspects such as polyploid plant genome assembly,origins and evolution,as well as three-dimensional genomes,and methylation modifications over the past several years.Additionally,it explores the current status and future prospects of polyploid telomere-to-telomere(T2T)genomes and graph pangenomes.
