- Key message
- In the paddy field, the bright green leaf (bgl) mutants of rice (Oryza sativa) exhibit a luminous green color that is clearly distinguishable from the normal green of wild-type plants
- Transmission and scanning electron microscopy revealed that small cuticular papillae (or small papillae; SP), nipple-like structures, are absent on the adaxial and abaxial leaf surfaces of bgl mutants, leading to more direct reflection and less diffusion of green light
- The rice bright green leaf (bgl) locus encodes OsRopGEF10, which activates the development of small cuticular papillae on leaf surfaces
- In agreement with the timing of SP initiation on the leaf epidermis, OsRopGEF10 is most strongly expressed in newly developing leaves before emergence from the leaf sheath
- The RAC/ROP GTPase Activator OsRopGEF10 functions in crown root development by regulating cytokinin signaling in rice.
- Loss of OsRopGEF10 function reduced the expression of the response regulator gene OsRR6, a repressor of cytokinin signaling, and impaired crown root development
- Mutations in OsAHP1/2 led to increased crown root production and rescued the crown root defect of Osropgef10
- Mutations of OsRopGEF10 induced hypersensitivity to cytokinin, whereas overexpressing this gene reduced the cytokinin response
- Connection
- OsRac1, OsRopGEF10~BGL, The rice bright green leaf bgl locus encodes OsRopGEF10, which activates the development of small cuticular papillae on leaf surfaces, In yeast two-hybrid assays, OsRopGEF10 interacts with OsRac1, one of seven OsRac proteins; consistent with this, both proteins are localized in the plasma membrane
- OsRac1, OsRopGEF10~BGL, The rice bright green leaf bgl locus encodes OsRopGEF10, which activates the development of small cuticular papillae on leaf surfaces, These results suggest that OsRopGEF10 activates OsRac1 to turn on the molecular signaling pathway for SP development
- OsRopGEF10~BGL, OsRR6, The RAC/ROP GTPase Activator OsRopGEF10 functions in crown root development by regulating cytokinin signaling in rice., Loss of OsRopGEF10 function reduced the expression of the response regulator gene OsRR6, a repressor of cytokinin signaling, and impaired crown root development
