S. Sakai et Y. Maniwa, INHIBITION OF ETHYLENE SYNTHESIS IN MUNG BEAN HYPOCOTYL SEGMENTS BY THE PROTEINACEOUS INHIBITORS OF ETHYLENE SYNTHESIS, Plant physiology and biochemistry, 32(3), 1994, pp. 385-389
The effects of proteinaceous inhibitors of ethylene synthesis isolated
from etiolated mung bean hypocotyls and from mung bean seeds were inv
estigated using both indole-3-acetic acid (IAA)-treated and 1-aminocyc
lopropane-1-carboxylic acid (ACC)-treated mung bean hypocotyl segments
. These inhibitory proteins reversibly inhibited ethylene synthesis by
IAA-treated mung bean segments. Similar reversible inhibitory effects
were also observed for ethylene synthesis from ACC by the segments. T
he inhibitory proteins had no effect on induction of ACC synthase by I
AA. These results indicate that the inhibitory effects are caused by i
nhibition of ethylene-forming enzyme activity.
