摘要

揭示植物对干旱的反应和随后的恢复所涉及的代谢和分子机制，对于确定可用于改善作物植物的耐旱机制至关重要。在这里，我们将植物生理学和生物化学，基因表达，定量蛋白质组学和代谢物分析相结合，以确定在植物经历和从干旱中恢复过程中起作用的遗传和代谢网络。转录本、蛋白质和代谢物的网络分析表明，三羧酸循环和脂质代谢等生物过程对叶片对干旱和恢复的响应具有重要影响。碳水化合物氧化途径的刺激被证明是产生能量和前体的关键节点，这些能量和前体是支持多种防御生存途径所需的。

Metabolism and Signalling in Pea (Pisum sativum) Leaves Exposed to Drought and Subsequent Recovery.

Uncovering the metabolic and molecular mechanisms involved in plant responses to drought and subsequent recovery, is essential to identify drought tolerance mechanisms that can be used to improve crop plants. Here we combine plant physiology and biochemistry, with gene expression, quantitative proteomics and metabolite profiling to identify the genetic and metabolic networks that operate in plants experiencing and recovering from drought. Network analysis of transcripts, proteins and metabolites revealed that certain biological processes such as the tricarboxylic acid cycle and lipid metabolism had a strong impact on the overall control of leaf responses to drought and recovery. The stimulation of carbohydrate oxidation pathways is demonstrated to be a key node in the generation of energy and precursors required to support diverse survival pathways of defence.
