| 为了解独脚金内酯生物合成最新研究进展，本研究以“独脚金内酯”为关键词，检索了2000—2020年NCBI数据库发表的相关文献资料，综述了近20年来独脚金内酯的生物合成通路和相关基因的功能研究进展，并对独脚金内酯在非生物胁迫作用中的功能以及与其他激素的相互作用进行概括。结果表明:1)独脚金内酯生物合成的通路是保存的，并可能与其他通路有交互作用；2)独脚金内酯的功能是多样的，在植物生长和发育的多个阶段发挥作用；3)独脚金内酯生物合成相关基因不仅是生物合成的关键基因，还可以与其他激素互作参与调控作用。在独脚金内酯生物合成及其调控作用的研究取得了重要突破的基础上，今后着重的研究方向可能是在产量形成机制、形态建成以及激素的调控作用机理等方面的研究。 |

| Abstract: |
| To further describe the latest research progress on strigolactone biosynthesis, by taking “trigolactone” as the keyword, the literatures published in the NCBI database from 2000 to 2020 are retrieved and summarized. The progress in the biosynthesis pathway and the functions of related genes of strigolactone in the past two decades are reviewed. The functions of strigolactone in abiotic stress and its interaction with other hormones are also summarized. The results show that: 1)The pathway of strigolactone biosynthesis is preserved and may interact with other pathways; 2)The functions of strigolactone are diverse and play a role in multiple stages of plant growth and development; 3)Genes related to the biosynthesis of strigolactone are not only the key genes of biosynthesis, but also interact with other hormones participating in the regulation. Therefore, on the basis of important breakthroughs in the studies on the biosynthesis and regulatory effects of strigolactone, future studies may focus on the yield formation mechanism, morphological formation and regulatory mechanism of hormones. |
