1In Vivo Phenotyping for the Early Detection of Drought Stress in Tomato显示文摘Drought stress imposes a major constraint over a crop yield and can be expected to grow in importance if the climate change predicted comes about.Improved methods are needed to facilitate crop management via the prompt detection of the onset of stress.Here,we report the use of an in vivo OECT(organic electrochemical transistor)sensor,termed as bioristor,in the context of the drought response of the tomato plant.The device was integrated within the plant’s stem,thereby allowing for the continuous monitoring of the plant’s physiological status throughout its life cycle.Bioristor was able to detect changes of ion concentration in the sap upon drought,in particular,those dissolved and transported through the transpiration stream,thus efficiently detecting the occurrence of drought stress immediately after the priming of the defence responses.The bioristor’s acquired data were coupled with those obtained in a high-throughput phenotyping platform revealing the extreme complementarity of these methods to investigate the mechanisms triggered by the plant during the drought stress event.Michela Janni Nicola Coppede Manuele Bettelli Nunzio Briglia Angelo Petrozza Stephan Summerer Filippo Vurro Donatella Danzi Francesco Cellini Nelson Marmiroli Domenico Pignone Salvatore Iannotta Andrea Zappettini 2019Plant Phenomics2019,1,1:1
