ABSTRACT
To separate and identify chemical signals which induce Thesium chinense haustorium formation, the components of T. chinense roots secretion collected with XAD-4 resin were detected by GC-MS. The effect of DMBQ as exogenous signals to induce haustorium formation in T. chinense was studied. Fifty-three compounds of 9 types had been detected, including hydrocarbons, esters, organic acids, ketones, alcohols, nitrogen containing compounds, phenolic acids, aldehyde and quinine. It is worth noting that the 2, 5-di-tert-butyl-1,4-benzoquinone has the core structure of 1,4-benzoquinone, which may play an important role in the parasitic relationship of Prunella vulgaris and T. chinense DMBQ worked effectively on inducing haustoria, but induction effects vary widely in different concentrations. DMBQ with the concentration of 1 μmol x L(-1) showed the best effect of the inducing ability with a ratio of 110.52 when treated to induce haustoria.
