µCT videos for: A water droplet lands on the leaf surface: What happens next?

µCT videos of data collected at the DANMAX beamline of MAX IV. Data shows how hydraulic activation of stomata can be achieved using a controlled system with high humidity and low CO2 content. Waterfilms containing iohexole for contrast were applied to barley and potato leaves at varying surface tensions and then scanned at times ranging from 30 min to 14 hours after application. All plants are scanned in a custom build sample holder keeping the plants in a controlled atmosphere and exposed to as little radiation as possible.

本数据集为在马克斯四世（MAX IV）同步辐射光源的DANMAX光束线采集的显微计算机断层扫描（µCT）视频数据。数据展示了如何通过高湿度、低二氧化碳浓度的可控系统实现气孔的水力激活。研究人员以不同表面张力将搭载碘海醇（iohexole）作为造影剂的水膜涂布于大麦与马铃薯叶片，随后于涂布后30分钟至14小时的多个时间节点开展扫描。所有植株均置于定制样品架中完成扫描，该样品架可维持植株处于可控大气环境，并尽可能降低辐射暴露量。
