Abstract

Perennial crops are promising candidates for building climate resilient agricultural systems because they can sustain production in challenging environments and their deep roots mitigate soil erosion, nutrient leaching and preserve soil carbon. However, these plants are challenging to breed with classical approaches due to self-incompatibility, polyploidy, and large complex genomes. These factors have been a barrier to cultivar development, but with the advances in genomic technologies, this can change. The possibility of assembling genomes and generating molecular markers in a cost-effective way means that cultivars can be developed faster with marker-assisted selection similarly to major crops. Here, we describe a pathway to accelerate domestication, starting from the establishment of a diversity collection, assembly of a reference genome, the development of breeding populations, and use of sequencing to identify relevant alleles. We provide recommendations to successfully use genomics to accelerate domestication given an entirely new era of DNA sequencing technologies.

加速多年生植物基因组化驯化
多年生作物是建立气候适应性农业系统的有希望的候选者,因为它们可以在具有挑战性的环境中维持生产,而且它们的深根可以减轻土壤侵蚀、养分淋失和保存土壤碳。然而,由于这些植物具有自交不亲和、多倍体和大而复杂的基因组,用传统方法进行育种具有挑战性。这些因素一直是品种发展的障碍,但随着基因组技术的进步,这种情况可以改变。以经济有效的方式组装基因组和产生分子标记的可能性意味着,与主要作物类似,可以通过标记辅助选择更快地开发栽培品种。在这里,我们描述了一条加速驯化的途径,从建立多样性收集,组装参考基因组,培育育种群体,以及使用测序识别相关等位基因开始。在DNA测序技术的全新时代,我们提供了成功使用基因组学来加速驯化的建议。

期刊介绍: Science has many big remaining questions. To address them, we will need to work collaboratively and across disciplines. The goal of iScience is to help fuel that type of interdisciplinary thinking. iScience is a new open-access journal from Cell Press that provides a platform for original research in the life, physical, and earth sciences. The primary criterion for publication in iScience is a significant contribution to a relevant field combined with robust results and underlying methodology. The advances appearing in iScience include both fundamental and applied investigations across this interdisciplinary range of topic areas. To support transparency in scientific investigation, we are happy to consider replication studies and papers that describe negative results. We know you want your work to be published quickly and to be widely visible within your community and beyond. With the strong international reputation of Cell Press behind it, publication in iScience will help your work garner the attention and recognition it merits. Like all Cell Press journals, iScience prioritizes rapid publication. Our editorial team pays special attention to high-quality author service and to efficient, clear-cut decisions based on the information available within the manuscript. iScience taps into the expertise across Cell Press journals and selected partners to inform our editorial decisions and help publish your science in a timely and seamless way.
