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.
Transmission electron microscopy analysis
- Several striking features were observed in the thylakoid membrane structure in osstn8 chloroplasts
- Transmission electron microscopy analysis revealed that stacking of the grana is significantly reduced and the length of grana is dramatically increased in the chloroplasts of osstn8 mutants under natural growth conditions (Figure 6b,d,f).
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).
