摘要

竹子以其惊人的生长速度和经济意义，为研究快速生长植物器官发生的分子基础提供了一个理想的系统，尤其是在单子叶植物中，关于笋尖和闰分生组织的维持和分化的基因调控网络仍然是一个有争议的主题。我们在 10× 平台上采用了空间和单核转录组测序技术，精确剖析了竹笋不同组织和早期发育阶段的基因功能。我们的综合分析揭示了笋发育过程中独特的细胞轨迹，发现了参与原鳞茎分化、闰分生组织形成和维管组织发育的关键基因和通路。关键调控基因的空间和时间表达模式，特别是与激素信号转导和脂质代谢相关的基因，有力地支持了髓间分生组织起源于被包围的实质细胞的假说。髓间分生组织中特定基因的表达呈现有规律的分散分布模式，为了解驱动竹笋快速生长的复杂分子机制提供了线索。单个细胞核和空间转录组分析揭示了基因活动的全貌，加深了对器官发生的分子结构的理解，并为未来依赖特定细胞类型身份的基因组和遗传学研究提供了宝贵的资源。

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.
