biosynthesis can increase the crop yield. We previously reported that a triazole derivative, TIS108, inhibits SL biosynthesis. In this study, we synthesized a number of novel TIS108 derivatives. Structure–activity relationship studies revealed that 4-(2-phenoxyethoxy)-1-phenyl-2-(1H-1,2,4-triazol-1-yl)butan-1-one (KK5) inhibits the level of 4-deoxyorobanchol in roots more strongly than TIS108.

Strigolactones(SLs)是控制几种重要农艺性状(例如枝条分支,叶片衰老和胁迫耐受性)的植物激素之一。SL生物合成的操纵可以增加农作物的产量。我们先前曾报道过三唑衍生物TIS108抑制SL的生物合成。在这项研究中,我们合成了许多新颖的TIS108衍生物。结构-活性关系研究表明,4-(2-苯氧基乙氧基)-1-苯基-2-(1 H -1,2,4-三唑-1-基)丁丹-1-酮(KK5)抑制4根中的-deoxyorobanchol比TIS108更强。我们进一步发现,KK5处理的拟南芥显示出分支表型增加,而AtMAX3和AtMAX4的基因表达上调。这些结果表明KK5是水稻和拟南芥中一种特异的SL生物合成抑制剂。
