- Key message
- As a conserved microRNA (miRNA) family in plants, miR408 is known to be involved in different abiotic stress responses, including drought
- Interestingly, some studies indicated a species- and/or cultivar-specific drought-responsive characteristic of miR408 in plant drought stress
- These findings implied that miR408 could serve as a potential target for genetic manipulations to engineer perennial grass plants for improved water stress tolerance
- Analyses of gene expression patterns and functions indicated OsmiR408 is an embryo-specific miRNA that positively regulates grain size
- MiR408 Regulates Grain Yield and Photosynthesis via a Phytocyanin Protein.
- Further studies revealed that the cleavage of OsUCL8 by miR408 affects copper homeostasis in the plant cell, which, in turn, affects the abundance of plastocyanin proteins and photosynthesis in rice
- Connection
- miR408~OsMIR408~OsmiR408, OsmiR396, OsmiR396/Growth Regulating Factor modulate rice grain size through direct regulation of embryo-specific miR408, Our findings suggest that genetic regulatory networks comprising various miRNAs, such as OsmiR396 and OsmiR408, may be crucial for controlling rice grain size
- miR408~OsMIR408~OsmiR408, OsGRF8, OsmiR396/Growth Regulating Factor modulate rice grain size through direct regulation of embryo-specific miR408, Moreover, we revealed the direct regulatory effects of OsGRF8 on OsMIR408 expression
- miR408~OsMIR408~OsmiR408, OsUCL8, MiR408 Regulates Grain Yield and Photosynthesis via a Phytocyanin Protein., Further studies revealed that the cleavage of OsUCL8 by miR408 affects copper homeostasis in the plant cell, which, in turn, affects the abundance of plastocyanin proteins and photosynthesis in rice
