The field of plant genome sequencing has grown rapidly in the past 20 years, leading to increases in the quantity and quality of publicly available genomic resources. The growing wealth of genomic data from an increasingly diverse set of taxa provides unprecedented potential to better understand the genome biology and evolution of land plants. Here we provide a contemporary view of land plant genomics, including analyses on assembly quality, taxonomic distribution of sequenced species and national participation. We show that assembly quality has increased dramatically in recent years, that substantial taxonomic gaps exist and that the field has been dominated by affluent nations in the Global North and China, despite a wide geographic distribution of study species. We identify numerous disconnects between the native range of focal species and the national affiliation of the researchers studying them, which we argue are rooted in colonialism-both past and present. Luckily, falling sequencing costs, widening availability of analytical tools and an increasingly connected scientific community provide key opportunities to improve existing assemblies, fill sampling gaps and empower a more global plant genomics community.
在过去的 20 年中,植物基因组测序领域发展迅速,导致可公开获得的基因组资源的数量和质量都有所增加。越来越多样化的分类群的基因组数据不断丰富,为更好地理解陆地植物的基因组生物学和进化提供了前所未有的潜力。本文提供了对陆地植物基因组学的现代观点,包括对组装质量、测序物种的分类分布和国家参与情况的分析。结果表明,近年来组装质量有了显著提高,仍然存在大量的分类差距,而且该领域主要由富裕的北方国家和中国主导,尽管研究物种的地理分布广泛。我们发现研究物种的起源地与研究它们的研究人员的国家归属之间存在许多脱节,我们认为这些脱节是过去和现在的殖民主义的根源。幸运的是,测序成本的降低、分析工具的广泛可用性以及日益紧密联系的科学界为改进现有组装、填补采样空白和增强更全球化的植物基因组学社区提供了关键机会。
