Description Metabolites are important regulators of plant stress responses. The genetic architecture of metabolome variation underlying plant drought response (DR) and tolerance (DT) remains elusive. Here, we performed non-targeted metabolic profiling of 385 maize natural inbred lines grown under well-watered (WW) and drought-stressed (DS) conditions. The 385 maize inbred lines were sown and grown in two growth pools at Huazhong Agricultural University, Wuhan, China. Each pool was divided into 400 plots with equal area, and 14 plants of each inbred line were grown in the plot. Maize plant in one pool were well-watered and the soil moisture was kept at around 25% and plants in the other pool were stop irrigation at 4-leave stage. Soil moisture were monitored by using a Delta-T HH2 soil moisture meter. Once the soil moisture of drought-treated pool reached 10%, the top fully expanded leaves of at least three plants (at around 6-leaf stage) were pooled and snap-frozen in liquid nitrogen and stored at -80°C for later metabolite extraction. 20mg freeze-dried powder of each sample was extracted followed the Methanol/MTBE protocol, and analyzed on an ACQUITY UPLC HSS T3 1.8 µm 2.1x100mm Waters Column on a Waters Acquity UPLC system coupled to a Thermo Fisher Q Extractive.
