Agricultural traits of bz1 plants and transgenic rice lines overexpressing BZ1. a Phenotypic differences of wild-type (WT), bz1, and transgenic line BZ1ox2, BZ1ox3, and BZ1ox7 at the grain-filling stage grown in paddy fields. b qRT-PCR analysis of the expression of BZ1 in WT and BZ1 overexpressing lines. c-e Plant height (c), dry biomass (d) and dry spike (e) were increased in transgenic plants overexpressing BZ1. * and ** indicates significant differences between WT and bz1, BZ1 overexpressing lines by t-test at P < 0.05 and 0.01, respectively
