Lhcb1 mRNA accumulation in photobleached pOCA107–2 (WT), gun, cch, cs, and ch42 mutants. (A) cs is not a gun mutant. Wild-type and mutant plants were photobleached for 6 days as described in Materials and Methods, and Lhcb1 mRNA levels were determined as described in Fig. 1B. (B) ch42 is not a gun mutant. Seedlings were grown on Murashige–Skoog media for 3 days. After 3 days, albino ch42 homozygotes, wild-type, and gun mutant seedlings were transferred to media containing Nf and grown for 4 days under strong continuous light. Lhcb1 mRNA levels were determined as described in Materials and Methods.
