摘要
从第一个模式植物拟南芥被测序,植物基因组测序已经有21年的历史。随着科学技术的不断发展进步,测序成本大幅降低,基因组的组装质量显著提升。本文统计了2000-2020年间植物参考基因组从头测序的进展,分析了植物基因组测序数量变化与测序技术发展之间的联系,以及测序基因组大小与倍性及重复序列的关系,总结了历年来测序物种的主要分类及其在系统发生树的分布,最后讨论了未来植物基因组潜在的研究方向。
Since the first model plant,Arabidopsis thaliana(L.)Heynh,was sequenced in 2000,significant advances have been made in the sequencing of plant genomes over the last 21 years.With continuous development of technology,the cost of sequencing has greatly reduced and genome quality has significantly improved.The tremendous information hidden in these sequences should provide valuable resources for biological research.Here,we summarized and discussed the advances in plant reference genome de novo sequencing that have occurred over the last 21 years.We analyzed dynamic changes between the annual amount of sequenced plant genomes and sequencing technology,explored the relationship between sequenced genome size and chromosome ploidy and repetitive sequences,and summarized the main species classifications and distributions of sequenced plant genomes in the species phylogenetic tree.Finally,potential research hotpots of plant genomes were discussed.
