Rice grain yields of wild‐type (WT), OsmiR530‐overexpressing (miR530‐OE) and OsmiR530 target mimic (MIM530) rice lines, and knockout PLUS3‐domain‐containing protein (PL3‐KO) plants grown in a paddy field.

Traits	WT	miR530‐OE	MIM530	PL3‐KO
Yield per plot (kg)	1.64 ± 0.06	0.93 ± 0.09 (P < 0.001)	1.77 ± 0.08 (P = 0.018)	1.31 ± 0.07 (P < 0.001)
Yield comparison with WT (%)	—	−43.29	+7.93	−20.12

Plants were arranged in plots according to a randomized complete block design with four replicates. Three transgenic lines were mixed and grown in one plot. Nipponbare (WT) was used as a control. Plants were grown under natural conditions in Jinan, China in 2018. The planting density was 20 cm × 25 cm, with one plant per hill. Data are presented as the mean ± SD (n = 4 plots, 3.0 m² per plot). Significant differences were determined with Student's t‐test.
