Maize root bacteria degrade host-specialized metabolites through the lactonase BxdA

Project description:Root exudates contain specialised metabolites that affect the plant’s root microbiome. How host-specific microbes cope with these bioactive compounds, and how this ability shapes root microbiomes, remains largely unknown. We investigated how maize root bacteria metabolise benzoxazinoids, the main specialised metabolites of maize. Diverse and abundant bacteria metabolised the major compound in the maize rhizosphere MBOA and formed AMPO. AMPO forming bacteria are enriched in the rhizosphere of benzoxazinoid-producing maize and can use MBOA as carbon source. We identified a novel gene cluster associated with AMPO formation in microbacteria. The first gene in this cluster, bxdA encodes a lactonase that converts MBOA to AMPO in vitro. A deletion mutant of the homologous bxdA genes in the genus Sphingobium, does not form AMPO nor is it able to use MBOA as a carbon source. BxdA was identified in different genera of maize root bacteria. Here we show that plant-specialised metabolites select for metabolisation-competent root bacteria. BxdA represents a novel benzoxazinoid metabolisation gene whose carriers successfully colonize the maize rhizosphere and thereby shape the plant’s chemical environmental footprint

Bacterial tolerance to host-exuded specialized metabolites structures the maize root microbiome.

Project description:Plants exude specialized metabolites from their roots, and these compounds are known to structure the root microbiome. However, the underlying mechanisms are poorly understood. We established a representative collection of maize root bacteria and tested their tolerance against benzoxazinoids (BXs), the dominant specialized and bioactive metabolites in the root exudates of maize plants. In vitro experiments revealed that BXs inhibited bacterial growth in a strain- and compound-dependent manner. Tolerance against these selective antimicrobial compounds depended on bacterial cell wall structure. Further, we found that native root bacteria isolated from maize tolerated the BXs better compared to nonhost Arabidopsis bacteria. This finding suggests the adaptation of the root bacteria to the specialized metabolites of their host plant. Bacterial tolerance to 6-methoxy-benzoxazolin-2-one (MBOA), the most abundant and selective antimicrobial metabolite in the maize rhizosphere, correlated significantly with the abundance of these bacteria on BX-exuding maize roots. Thus, strain-dependent tolerance to BXs largely explained the abundance pattern of bacteria on maize roots. Abundant bacteria generally tolerated MBOA, while low abundant root microbiome members were sensitive to this compound. Our findings reveal that tolerance to plant specialized metabolites is an important competence determinant for root colonization. We propose that bacterial tolerance to root-derived antimicrobial compounds is an underlying mechanism determining the structure of host-specific microbial communities.

Multiomics of tomato glandular trichomes reveals distinct features of central carbon metabolism supporting high productivity of specialized metabolites

Project description:Glandular trichomes (GT) are specialized cell factories that have the capacity to produce large amounts of metabolites which can amount to over 10% of the leaf dry weight. The specific expression of secondary metabolite pathways in glandular trichomes has facilitated their elucidation. However, little is known about the connection between central carbon and specialized metabolism in these cells. To address this question, we used the type VI glandular trichomes from a cultivated (Solanum lycopersicum LA4024) and a wild tomato accession (Solanum habrochaites LA1777) as a model. Our study is based on metabolomics, transcriptomics, proteomics and 13C-labeling datasets of trichome and leaves samples. This comparative analysis allowed us to identify specific features of trichomes in comparison to leaves. Here, the transcript raw and RMA-normalized data is hosted.

De novo transcriptome assembly and characterization of medicinal plant Lithospermum officinale to discover putative genes involved in specialized metabolites biosynthesis

Project description:In this study, we have performed Illumina based RNA sequencing to characterize the transcriptome and expression profiles of genes expressed in 3 tissues of L. officinale. RNA sequencing and de novo transcriptome assembly of L. officinale resulted in a total of 77,047 unigenes with N50 value as 1524 bps. KEGG pathway and GO enrichment analysis using highly expressed unigenes across three tissues showed active secondary metabolic processes specifically enriched to the root of L. officinale. Expression of identified candidate unigenes for specialized metabolites biosynthesis were consistent with previous reports on accumulation of metabolites across different tissues of L. officinale.
