Sažetak
The mobile signals for systemic acquired resistance (SAR) in plants are plant-pathogen specific. It is known that salicylic acid (SA) enables the establishment of SAR in plants infected by biotrophic pathogens, but the nature of the long-distance mobile signal for SAR depends on the plant-pathogen system. The clubroot disease is one of the most devastating diseases affecting all the members within the plant family Brassicaceae by causing serious losses of vegetable crops worldwide. In this study, we wanted to investigate whether methyl-salicylate (MeSA) is a mobile form of SA implicated in this plant-pathogen interaction. We have chosen Arabidopsis thaliana as a host organism for Plasmodiophora brassicae – the causal agent of clubroot, because the infection process is fast and the resistance of Arabidopsis to P. brassicae is conferred by a small number of genes. Using a GC-MS method, we monitored the transport and the metabolism of exogenously applied deuterated salicylic acid and its derivative, deuterated methyl-salicylate, through the whole plant of healthy and P. brassicae-infected Arabidopsis. The results showed that MeSA is a mobile form of SA in Arabidopsis clubroots.
