Spatial regulation of strigolactone function

Strigolactones (独脚金内酯) are plant hormones that control many aspects of plant development and environmental responses. Despite recent and rapid progress in the biochemical and molecular understanding of strigolactone biosynthesis, transport, and signaling, our knowledge about where strigolactones are produced and where they act is fragmented (片断的). In this review, we summarize current knowledge about these aspects of strigolactones, obtained from mutant phenotypes, grafting experiments, gene expression patterns, and protein localization studies. We also discuss the potential of new imaging technologies to reveal the spatial regulation of strigolactone function.

独脚金内酯是一种植物激素，其参与植物多个方面的发育和环境响应过程。尽管近年来我们对于独脚金内酯生物合成的生化和分子方面有了更深的理解，然而我们对于独脚金内酯的合成和作用部位的了解还不够系统。本综述总结了现有的关于独脚金内酯的最新研究进展，这些主要通过表型突变、嫁接试验、基因表达模式及蛋白定位研究得到的结果。作者还讨论了一些潜在的可能用于揭示独脚金内酯功能空间调控的新成像技术。
