Effects of plant movements on free fatty acid levels and jasmonic acid accumulation. (A) Effect of shaking on free fatty acid levels in corn leaves. Plants were shaken for 15 s (upper panel); Free fatty acids were extracted and measured at times indicated in upper panel after treatment; (B) Effect of shaking on jasmonic acid accumulation after treatment with insect elicitor (IE, volicitin) or mechanical wounding (MW) for 1 h. Plants were shaken as above and then left standing for 30 min before treatment with IE or MW. (C) Effect of simulated rain on free fatty acid levels in corn leaves. Plants were treated with simulated rain for 30 s Free fatty acids were analyzed 30 min after rain treatment. Displayed are the ratios between linolenic acid (LnA) and stearic acid (StA). StA levels did not change upon treatments described herein. (D) Effects of rain on jasmonic acid accumulation after treatment with insect elicitor (IE) or mechanical wounding (MW) for 60 min. Different letters above each bar indicate statistical difference determined by ANOVA analysis followed by Tukey tests where appropriate (p < 0.05). * denotes significant differences (t-test, p ≤ 0.05). N = 6, error bars represent standard deviation.
