  • Key message
    • The knock down or knock out of OsUCL8 also increases grain yield, while the overexpression of OsUCL8 results in an opposite phenotype
    • 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
    • Spatial and temporal expression analyses showed that OsUCL8 was highly expressed in pistils, young panicles, developing seeds and inflorescence meristem, and was nearly complementary to that of OsmiR408
    • Interestingly, the OsUCL8 protein was localized to the cytoplasm, distinctive from a majority of phytocyanins which localize to the plasma membrane
