Photoreceptor currents in the wild type and ChR2-enriched RNAi transformant of Chlamydomonas reinhardtii (upper panels), and the content of ChR1 and ChR2 in the respective cells (lower panels). The photoreceptor currents (black lines) were deconvoluted into two kinetically different components: an early receptor current without a delay and a decay time of 3 ms (red lines), and a delayed late receptor current with a decay time of 30 ms (blue lines). The changes in the amplitudes of the early and late photoreceptor currents in the transformant relative to the wild type closely correlate with the changes in the content of ChR1 (red columns) and ChR2 (blue columns) (modified from Sineshchekov et al. [21] and Govorunova et al. [25]).
