- 32. Isolation of substances that trigger stomatal opening
抄録
Opening and closing of stomata are controlled by various conditions. The substance controlling stomatal closing is elucidated to be an abscisic acid. However, the substance controlling the stomatal opening is not completely clear. The aim of our study is to search for the endogenous substance that triggers stomatal opening in higher plants. We searched the active compound in several plants extracts using bioassay with epidermal strips of Commelina communis. Bioassay-guided fractionation of a 50% MeOH extract of Ipomoea tricolor enabled the isolation of two active compounds, cis-12-oxophytodienoic acid (OPDA) and sn-1-O-(cis-12-oxophytodienoyl)-sn-3-O-(β-galactopyranosyl)glyceride. These compounds enhanced stomatal opening of Commelina communis in darkness at micromolar concentrations. These results suggest that these compounds play a crucial role in stomatal opening. OPDA is a known precursor of jasmonic acid. Now, we examine the stomatal opening activity of other jasmonates.
