Non-targeted metabolomics reveals hormonal mechanisms regarding arbuscular mycorrhizal fungi- and Serendipita indica-mediated plant growth response in Camellia oleifera
Original language description
Camellia oleifolia is an important oilseed woody plant that can be colonized by root-associated endophytic fungi, but the mechanism of how they promote growth improvement remains unclear. This study was to analyze the changes in biomass production, secondary metabolite profile, auxins, and cytokinins in C. oleifolia seedlings by four arbuscular mycorrhizal fungi (Diversispora versiformis, Rhizophagus intraradices, Funneliformis mosseae, and a mixture of the three above) and Serendipita indica. After 16 weeks of fungal inoculations, the root fungal colonization rate showed diverse changes, with S. indica (75 %) and R. intraradices (67 %) having relatively higher colonization rates. In addition, S. indica and R. intraradices significantly increased aboveground biomass, root biomass, and root surface area, whereas D. versiformis exhibited no significant effect. Non-targeted metabolomics of S. indica- and R. intraradices-inoculated roots detected a total of 802 metabolites, with 65 differential metabolites (33 up-regulated and 32 down-regulated) by S. indica and 163 differential metabolites (96 up-regulated and 67 down-regulated) by R. intraradices. The enriched metabolic pathways of these differential metabolites mainly included amino acid metabolism, secondary metabolites biosynthesis, and plant hormone biosynthesis in association with nine substances. The inoculation of endophytic fungi had varying effects on endogenous auxin and cytokinin levels, where leaf indole butyric acid and trans-zeatin levels were positively correlated with aboveground biomass, and root indole acetic acid, dihydrozeatin, and trans-zeatin levels were positively correlated with root biomass. It is concluded that root-associated endophytic fungi mediate the growth improvement by affecting auxins and cytokinins.
