Ethylene-Mediated Production and Emission of Limonene Influence Brown Planthopper Preference for Rice Plants.

Volatile organic compounds (VOCs) play a key role in plant communication with other organisms in the natural environment. However, the regulatory role of the phytohormone ethylene in volatile production in plants remains unclear. In this study, we demonstrated that the application of an ethylene precursor and amplification of ethylene signaling make rice plants more attractive to brown planthopper (BPH) females for feeding and oviposition.

Adsorption Mechanism of Benzene Alkylation System Catalyzed by an Acid Catalyst: Effect of Pressure.

Alkylbenzene is an important chemical intermediate, and its industrial production is mainly through the alkylation reaction of benzene and olefin under the action of an acid catalyst. In this article, the adsorption mechanism of benzene/propylene binary in HY zeolite was first revealed by Monte Carlo molecular simulation. It was found that the adsorption mechanism of benzene and propylene changes at the adsorbate loading of 36 molecules/UC, and benzene plays a dominant role.
