Maize Stress DIESI-MS Data and R Script

Climatic change is an increasing challenge for agriculture that is driving the development of suitable crops in order to ensure supply for both human nutrition and animal feed. In this context, it is increasingly important to understand the biochemical responses of cells to environmental cues at the whole system level, an aim that is being brought closer by advances in high throughput, cost-efficient plant metabolomics. To support molecular breeding activities, we have assessed the economic, technical and statistical feasibility of using direct mass spectrometry methods to evaluate the physiological state of maize (Zea mays L.) plants grown under different stress conditions.

气候变化对农业而言是日益严峻的挑战，这推动了适配型作物的研发，以保障人类膳食营养与动物饲料的供应。在此背景下，从全系统层面解析细胞对环境信号的生化响应愈发重要，而高通量、低成本植物代谢组学（plant metabolomics）技术的进步正逐步推动这一研究目标的实现。为支撑分子育种工作，本研究评估了采用直接质谱（mass spectrometry）分析法评估不同胁迫条件下生长的玉米（Zea mays L.）植株生理状态的经济、技术与统计可行性。
