Seed germination is tightly regulated so that it only occurs in optimal environmental conditions; for root parasitic plants, this is the presence of a potential host plant revealed by strigolactone exudates. New research shows that, unexpectedly, this response to strigolactone bypasses the core gibberellin-dependent pathway for germination.

两条途径发芽种子。

种子发芽受到严格控制，因此仅在最佳环境条件下发生；对于根寄生植物，这是潜在的寄主植物的存在，其通过内酯基内酯渗出液显示出来。新的研究表明，出乎意料的是，这种对strigolactone的反应绕过了赤霉素依赖的核心发芽途径。
