Table II. Occurrence of different photoprotection mechanism in the genomes of representative strains of cyanobacteria and photosynthetic eukaryotes

The D1:2 copy homology analysis was performed with BLASTP ( Part of the data were imported from Zhang et al. (2012). LHCII/I, Light-harvesting complex II/I; Pcb, chlorophyll a/b binding light-harvesting protein; LL, low light ecotype; HL, high light ecotype.
