AbstractHydrogen peroxide (H2O2) production during the infection of Arabidopsis thaliana by the soybean cyst nematode Heterodera glycines was detected histochemically by the reaction of H2O2 with cerium chloride producing four different patterns of electron-dense precipitates of cerium perhydroxides. As A. thaliana is not a regular host of H. glycines, the defence response is considerable, but does not completely inhibit the development of the nematode. H2O2 was produced not only by cells mechanically damaged during invasion and feeding site induction by the nematode, but also by cells surrounding developing syncytia and cells which were neither in contact with the nematode nor with the syncytium. Die Lokalisation von Peroxid wahrend der Abwehrreaktion von Arabidopsis thaliana gegen den pflanzenparasitaren Nematoden Heterodera glycines - Die Bildung von Wasserstoffperoxid (H2O2) im Rahmen der Infektion von Arabidopsis thaliana durch den Sojabohnen-Zystennematoden Heterodera glycines wurde histochemisch durch die Reaktion von H2O2 mit Cerchlorid nachgewiesen, wobei vier verschiedene Muster elektronendichter Prazipitate von Cerperhydroxiden gebildet wurden. Da A. thaliana kein regularer Wirt von H. glycines ist, kommt es zu einer betrachtlichen Abwehrreaktion, die jedoch die Entwicklung des Nematoden nicht vollstandig verhindert. H2O2 wurde nicht nur von Zellen produziert, die im Laufe des Eindringens und der Induktion des Nahrzellensystems durch den Nematoden mechanisch beschadigt worden waren, sondern auch von Zellen, die sich entwickelnde Syncytien umgaben und von Zellen, die weder mit dem Nematoden noch mit dem Syncytium in Kontakt standen.

Cell suspension cultures are now recognized as important model materials for plant bioscience and biotechnology. Very few studies of metabolic comparisons between cell cultures and original plants have been reported, even though the biological identity of cultured cells with the normally grown plant is of great importance. In this study, a comparison of the metabolome for primary metabolites extracted from the leaves of Arabidopsis thaliana and cultured cells from an Arabidopsis suspension culture (cell line T87) was performed. The results suggest that although cell suspension cultures and Arabidopsis leaves showed similarities in the common primary metabolite profile, nonetheless, moderate differences in quantitative profile were revealed.
