Effects of rhizosphere fungi on the chemical composition of fruits of the medicinal plant Cinnamomum migao endemic to southwestern China

Abstract

Background This study examined how rhizosphere fungi influence the accumulation of chemical components in fruits of a small population species of Cinnamomum migao. Results Ascomycota and Basidiomycota were dominant in the rhizosphere fungal community of C. migao. Pestalotiopsis and Gibellulopsis were associated with α-Terpineol and sabinene content, and Gibellulopsis was associated with crude fat and carbohydrate content. There were significant differences in rhizosphere fungal populations between watersheds, and there was no obvious change between fruiting periods. Gibberella, Ilyonectria, Micropsalliota, and Geminibasidium promoted sabinene accumulation, and Clitocybula promoted α-Terpineol accumulation. Conclusion The climate-related differentiation of rhizosphere fungal communities in watershed areas is the main driver of the chemical composition of C. migao fruit. The control of the production of biologically active compounds by the rhizosphere fungal community provides new opportunities to increase the industrial and medicinal value of the fruit of C. migao.

Quality Control of Oleum Cinnamomi Assisted by Network Pharmacology Strategy

“…Oleum Cinnamomi is the essential oil obtained from Fructus Cinnamomi , which is the dry and ripe fruit of Cinnamomum migao , a large evergreen of the Lauraceae family [ 37 ]. C. migao is only distributed in the dry and hot valleys of the Karma-Fenglin Mountain region.…”

“…Fungal groups stimulate the plant body to produce secondary metabolites, which are often the medically active ingredients of medicinal plants. According to a report, sabinene, the secondary metabolites of saprophytic fungi, can reflect the quality of C. migao in different regions [ 37 ]. In this study, the content of quality markers in Luodian samples was much higher than those in other origins.…”

High-throughput sequencing reveals rhizosphere fungal community composition and diversity at different growth stages of Populus euphratica in the lower reaches of the Tarim River

“…Among them, Ascomycota had the highest relative abundance in sapling (81.20%), followed by mature (72.08%), and the lowest in overripe (38.74%), Basidiomycota had the highest relative abundance in overripe (57.25%), and the relative abundance in other periods was low (range 1.41%∼2.69%). Many studies have shown that Ascomycota and Basidiomycota were the dominant fungi in plant rhizosphere ( Chen et al, 2021 ). For example, in the rhizosphere of Picea asperata ( Liu et al, 2021 ), Castanopsis hystrix and Pinus massoniana ( Wang et al, 2021a ; Wang et al, 2021b ), the relative abundance of both fungi were higher than other fungi.…”

Different Arbuscular Mycorrhizal Fungi Established by Two Inoculation Methods Improve Growth and Drought Resistance of Cinnamomum Migao Seedlings Differently

“…Glomus is recognized as a dominant AMF genus in the Karst regions of Southwest China [ 25 ]. Furthermore, previous research has confirmed that C. migao can co-exist with some AM fungi [ 26 , 27 ], and recently a study has analyzed the effects of AMF on C. migao drought tolerance under water deficit conditions in Karst soils by assessing inoculated seedlings [ 28 ]. However, none has explored the effects of different AMF inoculation methods or synergistic interaction between AMF species and inoculation methods on C. migao performance.…”
