Erratum to: Electrochromism: a useful probe to study algal photosynthesis

In the original publication, Fig. 2e reports an incorrect spectrum of the Electrochromic Shift (ECS) signal in plants. The spectrum erroneously presented in this figure (obtained by Jean Alric, Institut de Biologie Physico Chimique, Paris) was measured under nonoptimum conditions to assess the ECS features. The new spectrum of the electrochromic signal in Arabidopsis thaliana leaves presented as a new panel (e) of Fig. 2 has been measured 100 ls after a flash and therefore represents a pure ECS contribution.
