False-Color Image of NPQ Generated by Video Imaging of Chlorophyll Fluorescence.

(A) Wild-type Chlamydomonas cells and a mutant strain defective in thermal dissipation.

(B) Wild-type Arabidopsis seedlings and seedlings of a mutant defective in thermal dissipation.

(C) Wild-type Chlamydomonas, the npq5 mutant strain, and the npq5 mutant strain complemented with the Lhcbm1 gene.

In (A) and (B), the mutant cells and seedlings appear dark blue, indicating a decrease in NPQ relative to the wild type, which appear green with some yellow-orange specks (as indicated on the false-color scale). (Figure courtesy of Dafna Elrad.)
