摘要

诱导高光合能力是许多草本双子叶植物对强光（HL）的关键适应反应；然而，控制这种反应的信号通路在很大程度上仍是未知的。在此，利用系统生物学方法来表征强驯化和弱驯化拟南芥材料对高光合能力的诱导。植物生长了5年在弱光（LL）条件下工作，并在随后暴露于HL期间测量时间分辨的光合生理、代谢组学和转录组学反应。在HL转移早期诱导高氮（N）同化率强烈预测了HL转移后期光合能力的诱导。氮同化速率的加快取决于现有有机酸（OA）储量的调动，以及在诱导高光合能力期间增加的从头OA合成。蔗糖生物合成能力的增强与高光合能力的诱导同时增加，淀粉生物合成能力的增加与淀粉分解代谢的增加相平衡。该系统分析支持一个模型，在该模型中，在HL转变的早期对N同化的有效诱导开始了诱导HL中高光合能力驯化所需的一连串事件。

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.
