Functional complementation of OscpSRP54a. a Phenotype of WT, pgl14 and complementary line C-pgl14. Bar = 20 cm; b Sequence analysis of the mutation site (red arrow) in WT, pgl14 and C-pgl14; cOscpSRP54a transcripts in WT, pgl14 and C-pgl14; d Pigment contents in WT, pgl14 and C-pgl14 in 8-week-old leaves. Data are means ± SD (n = 3). Means with different letters indicate significant differences according to One-way ANOVA and Duncan’s test (p ≤ 0.01).
