The gene family is the chief component of plant stress resistance and metabolism through activating the phosphorylation of downstream proteins. is widely used for the treatment of cardiovascular diseases in Asian countries. However, information about the gene family of is not clear. The aim of this study is to comprehensively analyze the gene family of and its response to phytohormone. Here, 33 genes were identified and divided into three subfamilies (SmSnRK1, SmSnRK2 and SmSnRK3) according to phylogenetic analysis and domain. genes within same subgroup shared similar protein motif composition and were unevenly distributed on eight chromosomes of . -acting element analysis showed that the promoter of genes was enriched with motifs. Expression pattern analysis revealed that genes were preferentially expressed in leaves and roots. Most genes were induced by ABA and MeJA treatment. Correlation analysis showed that and might positively regulate tanshinone biosynthesis; might positively regulate salvianolic acid biosynthesis. RNAi-based silencing of down-regulated the biosynthesis of tanshinones and biosynthetic genes expression. An in vitro phosphorylation assay verified that SmSnRK2.2 interacted with and phosphorylated SmAREB1. These findings will provide a valuable basis for the functional characterization of genes and quality improvement of
该基因家族是植物抗逆性和新陈代谢的主要组成部分,通过激活下游蛋白质的磷酸化发挥作用。在亚洲国家被广泛用于治疗心血管疾病。然而,关于该基因家族的信息尚不清楚。本研究的目的是全面分析该基因家族及其对植物激素的响应。在此,根据系统发育分析和结构域鉴定出33个该基因,并将其分为三个亚家族(SmSnRK1、SmSnRK2和SmSnRK3)。同一亚组内的基因具有相似的蛋白质基序组成,且在该植物的八条染色体上分布不均。顺式作用元件分析表明,该基因的启动子富含相关基序。表达模式分析显示,该基因在叶和根中优先表达。大多数该基因受脱落酸(ABA)和茉莉酸甲酯(MeJA)处理诱导。相关性分析表明,某两个基因可能正向调控丹参酮生物合成;另一个基因可能正向调控丹酚酸生物合成。基于RNA干扰的该基因沉默下调了丹参酮的生物合成及生物合成基因的表达。体外磷酸化试验证实SmSnRK2.2与SmAREB1相互作用并使其磷酸化。这些发现将为该基因的功能表征及某植物品质改良提供有价值的依据
