摘要

以异麦芽寡糖为主要原料的醋酸发酵产物由异麦芽寡糖和醋酸组成。本文研究表明,该发酵产物能增强水稻抗病基因的表达,其主要功能成分是乙酸。目前已有报道称乙酸能增强茉莉酸信号通路,而异麦芽寡糖在植物防御信号通路中的作用尚不清楚。在本研究中,我们证明了异麦芽寡糖可能将醋酸增强的茉莉酸信号途径的一部分转移到水杨酸信号途径,而水杨酸信号途径是另一条主要的防御途径。此外,异麦芽低聚糖的单糖成分葡萄糖和二糖麦芽糖对信号通路的影响很小,但三糖麦芽三糖对防御信号通路的影响与异麦芽低聚糖相似。

Effects of acetic acid fermentation product and its components on defense signaling in rice.

Acetic acid fermentation product made from isomalto-oligosaccharide as the main raw material is composed of isomalto-oligosaccharide and acetic acid. In this paper, we have shown that the fermentation product enhanced the expression of disease resistance genes in rice, and that its main functional component was acetic acid. It has been reported so far that acetic acid enhances the jasmonic acid signaling pathway, while the role of isomalto-oligosaccharide in plant defense signaling remains unclear. In this study, we demonstrated the possibility that isomalto-oligosaccharide shifted part of the jasmonic acid signaling pathway, which is enhanced by acetic acid, to the salicylic acid signaling pathway, which is the other major defense pathway. Furthermore, glucose, a constituent monosaccharide of isomalto-oligosaccharide, and a disaccharide maltose had little effect on the signaling pathway, but a trisaccharide maltotriose tended to have a similar effect to isomalto-oligosaccharide on the defense signaling pathway.

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
