The importance of angiosperms to sustaining humanity by providing a wide range of 'ecosystem services' warrants increased exploration of their genomic diversity. The nearly completed sequences for two species representing the major angiosperm subclasses, specifically the dicot Arabidopsis thaliana and the monocot Oryza sativa, provide a foundation for comparative analysis across the angiosperms. The angiosperms also exemplify some challenges to be faced as genomics makes new inroads into describing biotic diversity, in particular polyploidy (genome-wide chromatin duplication), and much larger genome sizes than have been studied to date.
被子植物通过提供广泛的“生态系统服务”对维持人类生存至关重要，这使得对其基因组多样性的探索亟待加强。代表主要被子植物亚纲的两个物种，即双子叶植物拟南芥和单子叶植物水稻，其近乎完成的序列为跨被子植物的比较分析奠定了基础。被子植物也体现了基因组学在描述生物多样性方面取得新进展时所面临的一些挑战，特别是多倍体（全基因组染色质复制）以及比迄今为止研究的基因组大得多的基因组规模。
