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 in the host plant's transport system. Import mechanisms and consequent accumulation of sucrose in syncytia were described recently (Hofmann et al., 2007). In the present work we studied the starch metabolism of syncytia. Using HPLC and microscopic analyses we demonstrated that syncytia store carbohydrates by starch accumulation. Further, we monitored the expression of genes involved in the starch metabolic pathway by gene chip analysis and qRT-PCR. Finally, we provide a functional proof of the importance of starch synthesis for nematode development using T-DNA insertion lines. We conclude that syncytia accumulate starch as a carbohydrate buffer to compensate for changing solute uptake by the nematode and as long-term storage during juvenile development.
