Annotated Information

Gene Symbol

• Os05g0480000 <=> OsSTN8,STN8

Function

• STN8 kinase is involved in photosystem II (PSII) core protein phosphorylation (PCPP).
• Loss-of-function of OsSTN8 suppresses the photosystem II core protein phosphorylation and interferes with the photosystem II repair mechanism in rice.

Phenotypic analysis

• The growth of osstn8 mutants was slower than that of WT (Figure S3a,c), and the growth retardation resulted in a flowering delay of approximately 7–10 days (Figure S3b).
• The contents of photosynthetic pigments were not significantly altered in osstn8 mutants compared with WT, but the chlorophyll a/b ratio was 3.2 in WT and 3.0 in osstn8 mutant leaves.

Expression

• The expression pattern of OsSTN8 was determined by real-time PCR analysis (Figure 1d). OsSTN8 was found to be highly expressed in leaves (photosynthetic organ).
• Its expression was much lower in roots, flowers and immature seeds.
