FIG. 8.

Nonphotochemical quenching of fluorescence under DCMU (A) and DBMIB (B) treatments. Modulated fluorescence traces (Fig. 2) were measured under the growth light intensity of 50 μmol of photons m⁻² s⁻¹. Results are means and standard errors of measurements on the same culture at 37°C (n = 3). Modified from reference 22 with permission of the publisher.
