“…The chemical composition of Taxus soil is very complex, and the contents of various allelochemicals vary greatly. The concentrations of some allelochemicals are very low, which can not be detected by traditional HPLC analysis . In this experiment, the concentration of nine allelochemicals with different polarities in the rhizosphere and non-rhizosphere soil of three Taxus was analyzed and compared by constructing UPLC-QQQ-MS/MS.…”

The action of allelopathy need that allelochemicals exist in the soil and reach a certain concentration. Also, the detection of allelochemicals in the soil is one of the most important research topics in the process of exploring allelopathy. To solve the problem of the simultaneous detection of allelochemicals with low concentrations and different polarities, a novel strategy for the quick detection of the allelochemicals in Taxus soil by microdialysis combined with UPLC-MS/MS on the basis of in situ detection without destroying the original structure of soil was developed for the first time in the work. The dialysis conditions were optimized by the Box–Behnken design (BBD): 70% methanol, 3 μL/min flow rate, and 3 cm long membrane tube. A reliable UPLC-MS/MS program was systematically optimized for the simultaneous detection of nine allelochemicals with different polarities. The results proved the differences in the contents and distributions of nine allelochemicals in three different Taxus soils.

“…This is consistent with the results of other studies on the concentration effect of "low promotion and high inhibition" in plant interaction [5,40]. The reason for the weakening of the promoting effect of high-concentration irrigation may be that the plant interaction becomes stronger when the concentration of F. carica root extract increases, while the physiological morphology of the young roots of T. cuspidata has not been fully formed, and the protective enzyme system and defense system in the plant are also poor, so they are more sensitive to plant metabolites and other external stimuli, and are more prone to disease and adversity [27,41,42].…”

“…In this test, F. carica root extract had a better-promoting effect on the growth of T. cuspidata than other parts (stem and leaf), so the F. carica root extract with a stronger promoting effect was selected for subsequent irrigation in the experiment. The plant morphology index can directly reflect the influence of water extract of some donor plants on the recipient plants, and plant height and base diameter are the most intuitive expression of its growth [27]. The effects of different concentrations of F. carica root water extract on plant height and base diameter of T. cuspidata were measured.…”

Our research group successfully designed the F. carica and Taxus cuspidata Sieb. et Zucc mixed forest, and confirmed that their interspecific relationship was stable and F. carica has a promoting effect on neighboring T. cuspidata growth. However, the promoting mechanism has not been elucidated. In this study, F. carica was used as the donor plant and T. cuspidata was used as the recipient plant. T. cuspidata seedlings were irrigated with F. carica root extracts of different concentrations (10.0, 20.0, 40.0 g·L−1), and the plant height, base diameter, photosynthetic parameters, photosynthetic pigments, MDA contents, and antioxidant enzyme activities were measured. Soil physical and chemical properties, enzyme activities, and microbial diversity were measured. The results showed that the abundance of growth-promoting bacteria increased and the number of pathogenic bacteria decreased in the rhizosphere of T. cuspidata soil. It was speculated that the chemicals secreted by F. carica roots interacted with soil microorganisms of T. cuspidata soil after enrichment, changed soil microbial diversity, and indirectly promoted the growth of T. cuspidata. UPLC-QTOF-MS/MS was used to analyze F. carica root water extract and F. carica root exudates, respectively, and it was found that the main components were similar. Therefore, the promoting effect of F. carica on T. cuspidata is mainly caused by the accumulation of potential chemicals in F. carica root exudates in the soil through interaction with soil microorganisms. Furthermore, the allelopathic-promoting mechanism of F. carica on T. cuspidata was discussed from various aspects, to provide a theoretical basis for the protection, breeding, and sustainable management of T. cuspidata resources.

“…Previous studies by our research group have demonstrated that taxanes are unique allelochemicals in Taxus forests, playing an important role in mixed cultivation of Taxus and neighbor plants, and we also explored a detection method for taxane allelochemicals. , Unfortunately, research on the dynamic processes of taxane allelochemicals in soil is still in its infancy, and a method of using flux to analyze the migration of taxane allelochemicals has not been developed. At the same time, the persistence of taxane allelochemicals in soil and their subsequent degradation products have not been clarified.…”

The migration and transformation of allelochemicals are important topics in the exploration of allelopathy. Current research on the migration of allelochemicals mostly uses soil column and thin layer methods and verifies it by sowing plant seeds. However, traditional methods inevitably ignore the flux caused by the movement of allelochemicals carried by water. In fact, the flux determines the amount of allelochemicals that directly affect plants. In this work, a method of microdialysis combined with a soil column and UPLC-MS/MS to detect the flux of allelochemicals was developed for the first time and successfully applied to the detection of five taxane allelochemicals in soil. Meanwhile, by adding taxane allelochemicals to the soil and detecting their transformation products using UPLC-MS/MS, the half-life of taxane in the soil was determined, and the transformation pathway of taxane allelochemicals in the soil was further speculated.
