Current methods for detecting ethylene in plants (Invited Review)

Ethylene plays critical roles in developmental and physiological processes and is thus an important subject of research. Cristescu et al. review current methods available for ethylene monitoring in plants, including gas chromatography, electrochemical sensing and laser-based detection, and compare them in terms of sensitivity, selectivity, time response and cost. Guidelines are provided for proper selection and application of the methodologies described, and some specific applications of laser-based detection of ethylene are illustrated using responses of Arabidopsis thaliana to nutritional treatments as an example.
