Abstract

Crop wild relatives of perennial fruit crops have a wealth of untapped genetic diversity that can be utilized for cultivar development. However, barriers such as linkage drag, long juvenility, and high heterozygosity have hindered their utilization. Advancements in genome sequencing technologies and assembly methods, combined with the integration of chromosome conformation capture have made it possible to construct high-quality reference genomes. These genome assemblies can be combined into pan-genomes, capturing inter- and intraspecific variations across coding and non-coding regions. Pan-genomes of perennial fruit crops are being developed to identify the genetic basis of traits. This will help overcome breeding challenges, enabling faster and more targeted development of new cultivars with novel traits through breeding and biotechnology.

在泛基因组学时代发掘多年生水果作物野生近缘植物的多样性。
多年生水果作物野生近缘种具有丰富的未开发遗传多样性,可用于栽培品种的开发。然而,连接阻滞、幼年期长和杂合度高等障碍阻碍了对它们的利用。基因组测序技术和组装方法的进步,再加上染色体构象捕捉技术的整合,使得构建高质量的参考基因组成为可能。这些基因组组装可以组合成泛基因组,捕捉编码区和非编码区的种间和种内变异。目前正在开发多年生水果作物的泛基因组,以确定性状的遗传基础。这将有助于克服育种方面的挑战,通过育种和生物技术更快、更有针对性地开发具有新性状的新栽培品种。
