Abstract

Strigolactones (SLs) are a class of carotenoid-derived terpenoid lactones. Recent studies have revealed the mechanisms by which endogenous SLs control numerous aspects of plant architecture formation and growth, including shoot branching, root architecture development, and the responses to various environmental stresses such as drought, cold, and low-phosphorus and low-nitrogen levels. As a relatively newly discovered type of plant hormone, SLs are gaining attention for their exceptional development value and application potential in the fields of agricultural science and forestry biology. In this review, we initially summarize the discovery history and structural characteristics of SLs. Then, we introduce the physiological regulatory patterns and molecular regulatory mechanisms of SLs in plant growth and development regulation, abiotic stress adaptation, and the interactions of SLs with other hormones. Finally, we discuss recent advances in SL research in forest trees and outline future research frontiers and emerging techniques involving SLs. Thus, this review provides theoretical guidance and technical support for the physiological and molecular basis of SL use in regulating plant growth and development and offers new perspectives for investigating the genetic regulatory networks of important traits for improved plant breeding via molecular design.

独角子内酯在一年生和多年生植物中的多方面功能：发育调控、植物激素串扰和非生物胁迫

独角孤内酯（SLs）是一类类胡萝卜素衍生的萜类内酯。最近的研究揭示了内源SLs控制植物构型形成和生长的许多方面的机制，包括茎枝分枝、根构型发育以及对干旱、寒冷、低磷低氮等各种环境胁迫的响应。SLs作为一种较新发现的植物激素，因其在农业科学和林业生物学领域的特殊开发价值和应用潜力而备受关注。本文首先对SLs的发现历史和结构特征进行了综述。然后介绍了SLs在植物生长发育调控、非生物胁迫适应、与其他激素相互作用等方面的生理调控模式和分子调控机制。最后，我们讨论了森林树木SL研究的最新进展，概述了未来的研究前沿和涉及SL的新兴技术。本研究为SL调控植物生长发育的生理和分子基础提供理论指导和技术支持，为通过分子设计研究植物重要性状的遗传调控网络提供新的视角。

期刊介绍： The journal Plant Stress deals with plant (or other photoautotrophs, such as algae, cyanobacteria and lichens) responses to abiotic and biotic stress factors that can result in limited growth and productivity. Such responses can be analyzed and described at a physiological, biochemical and molecular level. Experimental approaches/technologies aiming to improve growth and productivity with a potential for downstream validation under stress conditions will also be considered. Both fundamental and applied research manuscripts are welcome, provided that clear mechanistic hypotheses are made and descriptive approaches are avoided. In addition, high-quality review articles will also be considered, provided they follow a critical approach and stimulate thought for future research avenues. Plant Stress welcomes high-quality manuscripts related (but not limited) to interactions between plants and: Lack of water (drought) and excess (flooding), Salinity stress, Elevated temperature and/or low temperature (chilling and freezing), Hypoxia and/or anoxia, Mineral nutrient excess and/or deficiency, Heavy metals and/or metalloids, Plant priming (chemical, biological, physiological, nanomaterial, biostimulant) approaches for improved stress protection, Viral, phytoplasma, bacterial and fungal plant-pathogen interactions. The journal welcomes basic and applied research articles, as well as review articles and short communications. All submitted manuscripts will be subject to a thorough peer-reviewing process.
