<i>Sclerotinia</i> <i>sclerotiorum</i> Infection Triggers Changes in Primary and Secondary Metabolism in <i>Arabidopsis thaliana</i>

Sclerotinia sclerotiorum is a devastating plant pathogen that causes substantial losses in various agricultural crops. Although plants have developed some well-known defense mechanisms against invasive fungi, much remains to be learned about responses fungal pathogens. In this study, we investigated how S. infection affects primary and secondary metabolism the model Arabidopsis thaliana. Our results showed soluble sugar amino acid content changed significantly A. thaliana leaves upon colonization, with decrease sucrose an increase mannitol, attributed biosynthesis. Furthermore, jasmonate signaling pathway was rapidly activated by infection, there striking accumulation of antifungal metabolites such as camalexin, p-coumaroyl agmatine, feruloyl N ? -acetylornithine. On other hand, characteristic compounds Brassicaceae, glucosinolates, were not induced infected sclerotiorum. study provides better understanding modified during like has both hemibiotrophic necrotrophic stages.
