	Plant height (cm)	Panicle per plant	Panicle length (cm)	Seed-set rate	Weight per 1,000 grains (g)	Yield/plant (g)
ME1-P	110.50 ± 3.36	12.30 ± 2.00	25.75 ± 0.39	0.73 ± 0.02	23.36 ± 1.13	32.11 ± 2.70
ME1-N	112.00 ± 1.30	12.70 ± 0.44	27.33 ± 1.33	0.70 ± 0.03	22.76 ± 1.10	32.20 ± 1.74
ME2-P	107.05 ± 3.20	12.73 ± 1.76	24.80 ± 0.44*	0.71 ± 0.06	23.86 ± 1.13	30.27 ± 9.22
ME2-N	112.87 ± 2.66	14.63 ± 1.14	25.94 ± 0.40	0.74 ± 0.01	24.29 ± 1.01	38.72 ± 2.54

ME1-P and ME2-P represent homozygous transgenic lines of ME1 and ME2, while ME1-N and ME2-N are their corresponding negative transgenic lines.

^aThe parameters were given as means (±standard deviation) for data collected from 10 plants in triplicate for each plant type.

^*Means significantly different from the control (P < 0.05).
