The ECS technique, based on absorbance shift of pigments, is used for quantitative studies on photosynthetic energy transduction. It is currently utilized to monitor post-illumination decay of proton-motive force and to analyze electron transmission along the photosynthetic chain.
The absorbance shift of pigments is proportional to the membrane potential (Delta psi) in plants, green algae, and many photosynthetic bacteria. It is currently denoted as ElectroChromic Shift (ECS) at 515-520 nm for plant carotenoids. It is increasingly being used for phenotyping plants for traits related to photosynthesis or chloroplast metabolism because it is a non-invasive technique and also because more instruments are now commercially available from various manufacturers. The ECS technique is currently used to monitor the post-illumination decay of the proton-motive force (pmf), but it has a more general use for quantitative studies on photosynthetic energy transduction. Here we briefly summarize the basic knowledge on ECS, emphasize the full potential of this technique, and propose a quantitative analysis of the photosynthetic performance with the definition of a transmission coefficient for electrons along the photosynthetic chain.
