Summary: This study reported the haustorium-inducing activity of p-benzoquinone and 2,6-dimethoxy-p-benzoquinone on different broomrape species, suggesting a role for benzoquinones in haustorium induction in these parasitic plants. The redox property of p-benzoquinone is invoked to explain the differential activity observed between the two compounds. These findings confirm the usefulness of benzoquinones as haustorium-inducing factors for holoparasitic plant research.

Summary: Buckwheat roots exhibit allelopathic potential on the radicle growth of Phelipanche ramosa, attributed to the presence of quercetin. Quercetin also induces haustorium formation in P. ramosa, along with inhibitory effects on radicle growth.

Summary: Cuscuta campestris, a parasitic weed species causing global harm to broadleaf crops, lacks effective control methods. Hydrocinnamic acid, with potential anti-C. campestris properties, was studied through structure-activity relationship analysis of 21 analogues, providing insights for designing more effective herbicides.

Summary: This study investigates the inhibitory effects of trans-cinnamic acid and its derivatives on the growth of Cuscuta campestris, a parasitic weed causing significant yield losses in crops. The findings reveal that some derivatives of trans-cinnamic acid exhibit enhanced growth inhibition activity against C. campestris seedlings, with the methyl ester derivative being the most active compound. This structure-activity relationship study provides valuable information for the design of herbicidal treatments targeting parasitic weeds.

Summary: Parasitic broomrape plants Orobanche cumana and Phelipanche aegyptiaca pose a serious threat to crops in China, but their potential suitable areas and risk zones have not been accurately predicted. This study used MaxEnt to predict their potential suitable areas and identified the factors affecting their distribution. The results showed the potential risk zones of O. cumana and P. aegyptiaca and suggested that their risk zones will shift northward under future climate change scenarios.

Summary: The study successfully developed a CLas enrichment system using the dodder plant as a host to acquire and enrich CLas from infected citrus shoots. The dodder plant showed the ability to support high levels of CLas multiplication and provided higher resolution genomic and transcriptomic analyses of CLas, making it an optimal model for future studies on the CLas-host interaction.

Summary: In high-power systems of proton exchange membrane fuel cells (PEMFC), cooling systems for the balance of plants (BOP) play an important role in maintaining temperature. A Simulink model and an AMEsim model are used to evaluate the effect of the BOP cooling system on fuel cell efficiency. Simulation results show that increasing stack output power, coolant flowrate, and radiator fan speed increases parasitic power and decreases PEMFC system efficiency.
