Yumi Eguchi, Ani Widiastuti, Hiromitsu Odani, Yufita Dwi Chinta, Maki Shinohara, Hideyuki Misu, Haruna Kamoda, Tomofumi Watanabe, Morifumi Hasegawa, Tatsuo Sato. Physiological and Molecular Plant Pathology 94, 83-89 2016/05/19 doi:10.1016/j.pmpp.2016.05.004 Enhanced antifungal activity by hot water treatment at 50 °C 20 s against Botrytis cinerea Pers. ex Fr., a gray mold pathogen was evaluated in thyme (Thymus vulgaris L.) Thymol, p-cymene, and γ-terpinene were detected as the main volatile compounds in thyme plants. Emission of p-cymene and γ-terpinene from thyme increased after treatment, whereas amount of thymol released did not change, suggested that existence of a thermo-dependent synthesis pathway of p-cymene and γ-terpinene. Volatile p-cymene inhibited mycelial growth of pathogen at 0.50 μL/ml, whereas γ-terpinene had an inhibitory effect at 0.05, 0.10, and 0.50 μL/ml. Transcript level of γ-terpinene gene increased after 24 h of treatment. As a conclusion, heat treatment enhanced antifungal activity by volatile terpenoids synthesized by thermo-dependent synthesis pathway of them in thyme.
  2. Research paper (scientific journal) Joint Organic hydroponics induces systemic resistance against the air-borne pathogen, Botrytis cinerea (gray mould) Yufita D. Chinta, Yumi Eguchi, Ani Widiastuti, Makoto Shinohara, Tatsuo Sato Journal of Plant Interactions 10/ 1, 243-251 2015/08/27 1742-9145 10.1080/17429145.2015.1068959 Here, we propose that organic hydroponics trigger induced systemic resistance (ISR) in lettuce against air-borne Botrytis cinerea, which causes gray mold. We compared effects of organic and chemical hydroponics, assessed presence of ISR elicitors in the hydroponic nutrient solution, and investigated molecular mechanism of ISR. Organic hydroponics significantly reduced gray mold lesions in lettuce (cultivated hydroponically) and cucumber (cultivated in soil and foliar sprayed with nutrient solution). The 1-aminocyclopropane-1-carboxylic acid synthase gene in lettuce and lipoxygenase and ethylene receptor-related gene in cucumber showed heightened expression, suggesting that the jasmonic acid/ethylene (JA/ET)-signaling pathway was involved in ISR for both crops. Low salicylic acid β-glucoside levels confirmed role of the ISR signaling pathway. ISR in both lettuce and cucumbers indicated that elicitors in organic hydroponics were nonhost-specific and that the JA/ET pathway was activated without microbe–root interaction. Thus, organic hydroponics can be an effective method for both soil-borne and air-borne disease control.
