BACKGROUND
Strigolactones are a unique class of plant metabolites which serve as a rhizosphere signal for parasitic plants and evocate their seed germination. The expansion of these parasitic weeds in the food crop fields urgently calls for their increased control and depletion. Simple strigolactone analogues able to stimulate seed germination of these parasitic plants may represent an efficient control measure through the induction of suicidal germination.
RESULTS
Triazolide-type strigolactone mimics were easily synthesized in three steps from commercially available materials. These derivatives induced effectively seed germination of Phelipanche ramosa with EC as low as 5.2 × 10 M. These mimics did not induce seed germination of Striga hermonthica even at high concentration (≥1 × 10 M).
CONCLUSIONS
Simple and stable strigolactone mimics with selective activity against Phelipanche ramosa were synthesized. © 2019 Society of Chemical Industry.
背景
独脚金内酯是一类独特的植物代谢物，作为根际信号诱导寄生植物种子萌发。这些寄生杂草在粮食作物田中的扩张迫切需要增加控制和消耗。能够刺激这些寄生植物种子萌发的简单独脚金内酯类似物可能通过诱导自杀性萌发成为一种有效的控制措施。
结果
三唑啉酮型独脚金内酯类似物可从商业上可获得的材料容易地通过三步合成。这些衍生物以低至 5.2×10 M 的 EC 有效地诱导独脚金寄生植物种子萌发。这些类似物即使在高浓度（≥1×10 M）下也不会诱导列当种子萌发。
结论
合成了对独脚金寄生植物具有选择性活性的简单稳定的独脚金内酯类似物。 © 2019 化学工业协会。
