HGT 获取基因的转移后适应以及对陆生植物鸟嘌呤代谢多样化的贡献。

水平基因转移（HGT）是原核生物和真核生物基因组进化的主要驱动力。尽管最近在分布和生态重要性方面取得了进展，但陆生植物中 HGT 获得基因的广泛模式（尤其是在种子植物中）和转移后的适应性仍然难以捉摸。我们系统地鉴定了 522 个陆生植物基因组中的 1150 个外来基因，这些基因可能是通过至少 322 次不同的非植物供体转移获得的，并证实最近的 HGT 事件在无籽和有籽植物中分布不均。由于内含子增殖，HGT获得的基因在平均内含子长度方面与本地基因更为相似，而且含有内含子的HGT获得的基因比缺乏内含子的基因表现出更高的表达水平，这表明内含子增殖可能参与了陆生植物HGT转移后的适应过程。细菌衍生基因 GuaD 在苔藓植物和裸子植物中的功能验证表明，外来基因的入侵引入了一种新的鸟嘌呤降解旁路，并导致一些裸子植物中原生途径基因的缺失，最终形成了陆生植物鸟嘌呤代谢的三大类型。我们的结论是，HGT 在陆生植物进化中发挥了关键作用。

期刊介绍： New Phytologist is an international electronic journal published 24 times a year. It is owned by the New Phytologist Foundation, a non-profit-making charitable organization dedicated to promoting plant science. The journal publishes excellent, novel, rigorous, and timely research and scholarship in plant science and its applications. The articles cover topics in five sections: Physiology & Development, Environment, Interaction, Evolution, and Transformative Plant Biotechnology. These sections encompass intracellular processes, global environmental change, and encourage cross-disciplinary approaches. The journal recognizes the use of techniques from molecular and cell biology, functional genomics, modeling, and system-based approaches in plant science. Abstracting and Indexing Information for New Phytologist includes Academic Search, AgBiotech News & Information, Agroforestry Abstracts, Biochemistry & Biophysics Citation Index, Botanical Pesticides, CAB Abstracts®, Environment Index, Global Health, and Plant Breeding Abstracts, and others.
