•The pdl1 mutant exhibits twisted leaves and malformed floral organs due to disrupted adaxial–abaxial polarity.•PDL1 encodes a cytoplasmic located SGS3 protein, which regulates tasiR-ARF synthesis to modulate OsARFs, while elevating abaxial miR165/166 and repressing adaxial OSHBs. Leaves and glumes...
