氢气(hydrogen,H2)是一种新的气体信号分子。藻类和微生物的氢酶可以产生并释放H2,高等植物也可能存在类似于氢酶的蛋白催化H2的合成。同时,各种非生物胁迫和激素也可诱导产生H2。与动物中H2通过选择性抗氧化预防和辅助治疗多种疾病所不同的是,植物中H2的生理作用可能还与其通过迅速诱导活性氧信号,从而调动抗氧化防护系统有关。H2具有多种植物学效应,包括调控生长发育和提高对生物胁迫和非生物胁迫的抗/耐性,其分子机制涉及对miRNA、基因表达、激素水平和蛋白质修饰的调控,并可能与一氧化氮(nitric oxide,NO)和一氧化碳(carbon monoxide,CO)等气体信号转导有关。H2的研究掀起了新一轮健康革命,"氢农业"的发展也已初具规模。本文主要综述了H2产生、生理功能以及与激素等信号分子互作的研究进展,并对H2植物学效应和"氢农业"进行了展望。
Hydrogen(H2)is a new gas signal molecule, and hydrogen enzymes from the algae and microorganism can produce and release H2. Higher plants may have hydrogen-like protein(s)that catalyze the production of H2, and the production of H2 is also induced by abiotic stresses and phytohormones. As a novel antioxidant, H2 has been proven effective in adjutant therapy. Importantly, the role of H2 in plants may also be related to the first rapidly induced reactive oxygen species signals, thus triggering antioxidant defense. H2 plays multiple biological roles, including regulating plant growth, development, and increasing plant tolerance/resistance against abiotic and biotic stresses;its molecular mechanisms involve in the regulation of miRNA, gene expression, phytohormone levels, and protein modification. In addition, nitric oxide(NO)and carbon monoxide(CO)are involved in the biological effects induced by H2. Recently, researches of H2 had set off a new round of healthy revolution, and the development of hydrogen agriculture was just a beginning. This paper mainly reviewed the research progress of H2 production, physiological functions, and interactions with hormones and other signaling molecules. Finally, the prospect of botanical effects of H2 and hydrogen agriculture was suggested.
