拟南芥FOLK（At5g58560）基因编码法呢醇激酶，其将法呢醇磷酸化为法呢基磷酸。FOLK基因的功能缺失突变与对脱落酸（阿坝）的敏感性增强有关，表明FOLK负调节阿坝信号传导。此外，民间花卉在水分胁迫下会产生额外心皮，这为法尼醇代谢、非生物胁迫信号和花发育之间的分子联系提供了证据。在这里，我们表明，法尼醇增加阿坝的敏感性和阿坝影响花发育拟南芥。
The Arabidopsis FOLK (At5g58560) gene encodes farnesol kinase, which phosphorylates farnesol to farnesyl phosphate. Loss-of-function mutations in the FOLK gene are associated with enhanced sensitivity to abscisic acid (ABA), suggesting that FOLK negatively regulates ABA signaling. Moreover, folk flowers develop supernumerary carpels under water stress, providing evidence for a molecular link between farnesol metabolism, abiotic stress signaling and flower development. Here, we show that farnesol increases ABA sensitivity and that ABA affects flower development in Arabidopsis.
