Bunge is a Chinese traditional herb for treating cardiovascular and cerebrovascular diseases, and tanshinones and phenolic acids are the dominated medicinal and secondary metabolism constituents of this plant. WRKY transcription factors (TFs) can function as regulators of secondary metabolites biosynthesis in many plants. However, studies on the WRKY that regulate tanshinones and phenolics biosynthesis are limited. In this study, 69 were identified in the transcriptome database of , and phylogenetic analysis indicated that some had closer genetic relationships with other plant , which were involved in secondary metabolism. Hairy roots of were treated by methyl jasmonate (MeJA) to detect the dynamic change trend of , biosynthetic genes, and medicinal ingredients accumulation. Base on those date, a correlation analysis using Pearson's correlation coefficient was performed to construct gene-to-metabolite network and identify 9 SmWRKYs (SmWRKY1, 7, 19, 29, 45, 52, 56, 58, and 68), which were most likely to be involved in tanshinones and phenolic acids biosynthesis. Taken together, this study has provided a significant resource that could be used for further research on SmWRKY in and especially could be used as a cue for further investigating SmWRKY functions in secondary metabolite accumulation.
当归属植物是一种传统的中草药,用于治疗心脑血管疾病,丹参酮和酚酸类化合物是该植物中主要的药用和次生代谢成分。WRKY 转录因子(TFs)可以作为许多植物次生代谢物生物合成的调节剂。然而,关于调节丹参酮和酚酸类生物合成的 WRKY 的研究还很有限。在本研究中,从转录组数据库中鉴定出了 69 个 SmWRKYs,系统发育分析表明,其中一些与其他植物的 WRKYs 具有更近的遗传关系,这些 WRKYs 参与次生代谢。用茉莉酸甲酯(MeJA)处理丹参毛状根,以检测 SmWRKYs、生物合成基因和药用成分积累的动态变化趋势。基于这些数据,使用 Pearson 相关系数进行了相关性分析,构建了基因-代谢物网络,并鉴定出 9 个可能参与丹参酮和酚酸类生物合成的 SmWRKYs(SmWRKY1、7、19、29、45、52、56、58 和 68)。总之,本研究提供了一个重要的资源,可用于进一步研究丹参中的 SmWRKY,特别是可以作为进一步研究 SmWRKY 在次生代谢物积累中的功能的线索。
