Table 2. In Vivo Phosphorylation Stoichiometry (Percentage of Phosphorylation) for the PSII Core Proteins from Wild-Type and pbcp-1 Leaves.

	Blue Light		Far-Red Light
Protein	Wild Type	pbcp-1	t Test	Wild Type	pbcp-1	t Test
P-D1	42 ± 4	60 ± 6	**	20 ± 3	45 ± 4	**
P-D2	42 ± 7	56 ± 9	*	17 ± 4	32 ± 2	**
P-PsbH	35 ± 6	40 ± 2		20 ± 3	42 ± 3	**
PP-PsbH	23 ± 9	37 ± 4	**	12 ± 6	19 ± 5

A single asterisk and a double asterisk represent statistically significant differences between the pbcp-1 mutant and the wild type at P < 0.05 and P < 0.01, respectively, in the Student’s t test.
