The role and proteomic analysis of ethylene in hydrogen gas-induced adventitious rooting development in cucumber (Cucumis sativus L.) explants.

ABSTRACT: Previous studies have shown that both hydrogen gas (H₂) and ethylene (ETH) play positive roles in plant adventitious rooting. However, the relationship between H₂and ETH during this process has not been explored and remains insufficiently understood. In this study, cucumber (Cucumis sativus L.) was used to explore the proteomic changes in ETH-H₂-induced rooting. Our results show that hydrogen-rich water (HRW) and ethylene-releasing compound (ethephon) at proper concentrations promote adventitious rooting, with maximal biological responses occurring at 50% HRW or 0.5 µM ethephon. ETH inhibitors aminoethoxyvinylglycine (AVG) and AgNO₃ cause partial inhibition of adventitious rooting induced by H₂, suggesting that ETH might be invo
