Abstract The plant parasitic nematode Heterodera schachtii induces specific syncytial feeding sites in the roots of Arabidopsis thaliana from where it withdraws all required nutrients. Therefore, syncytia have to be well supplied with assimilates and generate strong sinks host plant's transport system. Import mechanisms consequent accumulation sucrose were described recently. In this work, we studied starch metabolism syncytia. Using high-performance liquid chromatography microscopic analyses, demonstrated that store carbohydrates by accumulation. Further, monitored expression genes involved metabolic pathway gene chip analysis quantitative reverse transcription-PCR. Finally, provide functional proof importance synthesis for development using T-DNA insertion lines. We conclude accumulate as a carbohydrate buffer compensate changing solute uptake long-term storage during juvenile development.
