Ethylene production from eto1-1 grown in horizontal and vertical conditions

One hundred eto1-1 seedlings were placed on a dialysis membrane-covered agar plate in a sealed plastic container (6 × 4 × 1.8 cm). After 3-d incubation in horizontal or vertical conditions in the light, ethylene accumulation in the plastic container was measured.

Condition	Ethylene Accumulation/100 Seedlings	Ethylene Accumulation/g Fresh Weight
	nL	nL g−1
Horizontal	0.179 ± 0.023	7.10 ± 1.30
Vertical	0.165 ± 0.009	7.15 ± 0.59
