Strigolactones secreted by plant roots are exploited by parasitic plants as germination triggers, making their synthesis and signaling important targets for crop protection. Meanwhile, genetic analyses have identified several genes required for the synthesis and signaling of an unknown shoot branching inhibitor. Two recent papers unite these two fields, showing that strigolactones control shoot branching.
植物根系分泌的独脚金内酯被寄生植物用作萌发触发剂，这使得它们的合成和信号传导成为作物保护的重要目标。同时，遗传分析已经鉴定出了几种未知的茎分枝抑制剂合成和信号传导所需的基因。最近的两篇论文将这两个领域结合起来，表明独脚金内酯控制茎分枝。
