Strigolactones (SLs) control plant development, enhance symbioses, and act as germination stimulants for some of the most destructive species of parasitic weeds, making SLs a potential tool to improve crop productivity and resilience. Field trials demonstrate the potential use of SLs as agrochemicals or genetic targets in breeding programs, with applications in improving drought tolerance, increasing yields, and controlling parasitic weeds. However, for effective translation of SLs into agriculture, understanding and exploiting SL diversity and the development of economically viable sources of SL analogs will be critical. Here we review how manipulation of SL signaling can be used when developing new tools and crop varieties to address some critical challenges, such as nutrient acquisition, resource allocation, stress tolerance, and plant-parasite interactions.
独脚金内酯（SLs）控制植物发育，增强共生关系，并作为一些最具破坏性的寄生杂草物种的萌发刺激物，这使得 SLs 成为提高作物生产力和弹性的潜在工具。田间试验表明，SLs 作为农用化学品或遗传靶标在育种计划中具有潜在的应用，可用于提高耐旱性、增加产量和控制寄生杂草。然而，为了将 SLs 有效地应用于农业，理解和利用 SL 的多样性以及开发经济上可行的 SL 类似物来源将是至关重要的。在这里，我们回顾了在开发新工具和作物品种时，如何利用 SL 信号转导来应对一些关键挑战，例如养分获取、资源分配、胁迫耐受和植物-寄生虫相互作用。
