原始语种摘要: Summary(#br)Heterodera schachtii , a plant‐parasitic cyst nematode, invades host roots and induces a specific syncytial feeding structure, from which it withdraws all required nutrients, causing severe yield losses. The system H. schachtii –Arabidopsis is an excellent research model for investigating plant defence mechanisms. Such responses are suppressed in well‐established syncytia, whereas they are induced during early parasitism. However, the mechanisms by which the defence responses are modulated and the role of phytohormones are largely unknown. The aim of this study was to elucidate the role of hormone‐based defence responses at the onset of nematode infection. First, concentrations of main phytohormones were quantified and the expression of several hormone‐related genes was...
