摘要
通过对华南忍冬Lonicera confusa绿原酸、木犀草素生物合成关键酶基因进行组织特异性表达分析,阐明华南忍冬活性成分形成的分子调控机制。采用实时定量PCR分析方法分析绿原酸和木犀草素生物合成途径上的PAL,4CL,C4H,CHS,CHI,FNS,HQT基因家族成员在华南忍冬花蕾和叶中的表达情况。结果表明PAL1,C4H1,4CL1,CHS1,CHI3,HQT2在华南忍冬花蕾中的表达水平要低于叶,而PAL3,4CL2,CHI2,FNS2在花蕾中的表达水平要高于叶。推测华南忍冬PAL3,4CL2基因可能与绿原酸成分积累有关,同时PAL1,CHS1,CHI3,HQT2同源基因在华南忍冬花蕾和叶中的表达模式与忍冬不同,这为进一步研究忍冬与华南忍冬活性成分差异的遗传机制提供理论依据。
This study analysed the tissue specific expression of critical genes involved in chlorogenic acid and luteolin biosynthesis, for exploiting the molecular mechanism of components biosynthesis in Lonicera confusa. Expression of PAL, 4CL, C4H, CHS, CHI, FNS and HQT gene families of chlorogenic acid and luteolin biosynthesis-related genes in buds and leaves of L. confusa were analyed by Real-time PCR. Expressions of PAL1, G4H1, 4CL1, CHS1, CHI3 and HQT2 in buds were lower than that in leaves, and expressions of PAL3, 4CL2, CHI2 and FNS2 in buds were higher than that in leaves. The results indicated that that PAL3 and 4CL2 may be associated with accumulation of chlorogenic acid, and the expression patterns of PAL1, CHS1, CHI3 and HQT2 in buds and leaves of L. confusa were different with L. japonica. This study provided some theoretical basis for the further research on genetic mechanism of active components differences in L. confusa and L. japonica.
