陆地植物及其后代的起源标志着对陆地环境中生活的关键适应的进化，如根、维管组织和气孔。尽管这些创新有很好的特点，但人们对它们的发展和功能背后的遗传工具包的进化知之甚少。我们分析了532个物种的分子数据，以调查参与这些适应的发展和调节的基因的进化起源和多样性。我们发现，最初陆地植物中的新基因导致了气孔的单一起源，但种子植物的气孔关闭是后来基因扩张的结果。相比之下，导致维管组织起源的主要机制是第一批陆地植物中出现的基因的共选，使整个祖先维管植物能够持续地进行水分运输。反过来，具有真叶的植物和种子植物的祖先中新的关键基因导致了根和侧根的出现。这项分析强调了使植物征服陆地的不同进化模式，表明基因扩张和共选是植物进化史上最常见的生物创新机制。另见Fürst-Jansen等人对本文的评论，235：380-383。
The origin of land plants and their descendants was marked by the evolution of key adaptations to life in terrestrial environments such as roots, vascular tissue and stomata. Though these innovations are well characterized, the evolution of the genetic toolkit underlying their development and function is poorly understood. We analysed molecular data from 532 species to investigate the evolutionary origin and diversification of genes involved in the development and regulation of these adaptations. We show that novel genes in the first land plants led to the single origin of stomata, but the stomatal closure of seed plants resulted from later gene expansions. By contrast, the major mechanism leading to the origin of vascular tissue was cooption of genes that emerged in the first land plants, enabling continuous water transport throughout the ancestral vascular plant. In turn, new key genes in the ancestors of plants with true leaves and seed plants led to the emergence of roots and lateral roots. The analysis highlights the different modes of evolution that enabled plants to conquer land, suggesting that gene expansion and cooption are the most common mechanisms of biological innovation in plant evolutionary history.
