Abstract:
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, C4H1, 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.
