Abstract

Rooting and root development in Acer rubrum have important effects on overall growth. A. rubrum does not take root easily in natural conditions. In this study, the mechanisms of the miR396b- GRF1 module underlying rooting regulation in A. rubrum were studied. The subcellular localization and transcriptional activation of miR396b and its target gene growth regulating factor 1 ( GRF1) were investigated. These experiments showed that GRF1 was localized in the nucleus and had transcriptional activation activity. Functional validation experiments in transgenic plants demonstrated that overexpression of Ar-miR396b inhibited adventitious root growth, whereas overexpression of ArGRF1 increased adventitious root growth. These results help clarify the molecular regulatory mechanisms underlying adventitious root growth in A. rubrum and provide some new insights into the rooting rate in this species.

红槭生根调控miR396b-GRF1模块的分子机制

红槭的生根和根系发育对其整体生长有重要影响。草属植物在自然条件下不容易生根。本研究研究了miR396b- GRF1模块在红草生根调控中的作用机制。研究了miR396b及其靶基因生长调节因子1 (GRF1)的亚细胞定位和转录激活。这些实验表明，GRF1定位于细胞核，具有转录激活活性。在转基因植物中的功能验证实验表明，Ar-miR396b过表达抑制不定根生长，而ArGRF1过表达促进不定根生长。这些结果有助于阐明红草不定根生长的分子调控机制，并为该物种的生根率提供一些新的认识。

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.
