- Key message
- Using rice expression-microarray and northern blot analyses, we found that a large number of nucleus-encoded genes involved in chloroplast functions were highly expressed and transcripts of plastid-encoded genes, psaA, psbA and rbcL, increased in the OsGLK1-FOX calli
- Transmission electron microscopy showed the existence of differentiated chloroplasts with grana stacks in OsGLK1-FOX calli cells
- Furthermore, we found developed chloroplasts in vascular bundle and bundle sheath cells of coleoptiles and leaves from OsGLK1-FOX seedlings
- The OsGLK1-FOX calli exhibited high photosynthetic activity and were able to grow on sucrose-depleted media, indicating that developed chloroplasts in OsGLK1-FOX rice calli are functional and active
- These results strongly suggest that OsGLK1 regulates chloroplast development under the control of light and phytohormones, and that it is a key regulator of chloroplast development
- Ectopic overexpression of the transcription factor OsGLK1 induces chloroplast development in non-green rice cells
- In both lines, OsGLK1 cDNA encoding a GARP transcription factor was ectopically overexpressed
- Connection
- OsGLK1, OsPIL13~OsPIL1, Rice Phytochrome-Interacting Factor-Like1 OsPIL1 is involved in the promotion of chlorophyll biosynthesis through feed-forward regulatory loops., In addition, OsPIL1 directly up-regulates the expression of two transcription factor genes, GOLDEN2-LIKE1 (OsGLK1) and OsGLK2
