Background Plants grown in stony soils have better-developed root systems and higher crop yields than those grown in non-stony soils. The roles of various physical and chemical effects of stony soils on plant growth have been published, but the roles of soil microbiota and rhizosphere microbiota have not been investigated. Methods Tetrastigma hemsleyanum plants were cultivated for two years in stony soils and in the same soil from which rock-fragments had been removed. The microbiome and the tuber transcriptome were analyzed, using multiple bioinformatics methods. Results The soil microbiota of these two soils were markedly different, and the stony soils contained high abundances of bacterial taxa belonging to the Actinobacteria, Rokubacteria, Rhizobiales, Desulfarculaceae, and Chthoniobacteraceae. These discriminatory taxa in soils may promote the tuber growth of T. hemsleyanum, through releasing nutrients from rocks and colonizing the rhizosphere and tuber surface of T. hemsleyanum. In addition, stony soils induced a dramatic change in the tuber’s transcriptome, particularly with respect to the pathways of phytohormone biosynthesis, photosynthesis, and biotic stress resistance, expression levels of which showed strong correlations with the aforementioned bacterial taxa. Conclusions These results indicated that beneficial effects of stony soils on plant growth may be closely correlated with their specific microbiota, which can, in turn, influence multiple biological processes of host. This is the first study to reveal the role of stony soils-driven microbiota in tuber growth, and stony soils can represent a microbial repository for the screening of microbial isolates to increase plant yield.

“…N-feruloyl tyramine is considered a phytoalexin because it has antifungal activity and its biosynthesis is elicited by wounding and pathogen attack in many species, in particular solanaceous plants (Negrel and Martin, 1984;Negrel and Jeandet, 1987;Newman et al, 2001;Guillet and de Luca, 2005;Zacar es et al, 2007;Kim et al, 2011;Campos et al, 2014;Macoy et al, 2015). The amide can be further integrated into cell walls via peroxidase-mediated catalysis yielding ether bonds (Guillet and de Luca, 2005).…”

Summary Enzyme promiscuity, a common property of many uridine diphosphate sugar‐dependent glycosyltransferases (UGTs) that convert small molecules, significantly hinders the identification of natural substrates and therefore the characterization of the physiological role of enzymes. In this paper we present a simple but effective strategy to identify endogenous substrates of plant UGTs using LC‐MS‐guided targeted glycoside analysis of transgenic plants. We successfully identified natural substrates of two promiscuous Nicotiana benthamiana UGTs (NbUGT73A24 and NbUGT73A25), orthologues of pathogen‐induced tobacco UGT (TOGT) from Nicotiana tabacum, which is involved in the hypersensitive reaction. While in N. tabacum, TOGT glucosylated scopoletin after treatment with salicylate, fungal elicitors and the tobacco mosaic virus, NbUGT73A24 and NbUGT73A25 produced glucosides of phytoalexin N‐feruloyl tyramine, which may strengthen cell walls to prevent the intrusion of pathogens, and flavonols after agroinfiltration of the corresponding genes in N. benthamiana. Enzymatic glucosylation of fractions of a physiological aglycone library confirmed the biological substrates of UGTs. In addition, overexpression of both genes in N. benthamiana produced clear lesions on the leaves and led to a significantly reduced content of pathogen‐induced plant metabolites such as phenylalanine and tryptophan. Our results revealed some additional biological functions of TOGT enzymes and indicated a multifunctional role of UGTs in plant resistance.

“…This is the time-point when metabolite accumulation is detected in infected transgenic rice, and most of these metabolites are associated with pathogen resistance. In addition, studies have also shown that exogenous application of metabolites (such as GABA, dopamine, proline, tyramine) can increase plant resistance [27,44,45,46]. From the metabolites accumulated in MoSDT1-transgenic rice infected by M. oryzae, six metabolites (galactinol, tyramine, L-glutamine, L-tryptophan, pinene and dopamine) were selected to treat M. oryzae-infected rice in two ways exogenously.…”

Background: Some of the pathogenic effector proteins play an active role in stimulating the plant defense system to strengthen plant resistance.Results: In this study, ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UHPLC/Q-TOF-MS) was implemented to identify altered metabolites in transgenic rice containing over-expressed M. oryzae Systemic Defense Trigger 1 (MoSDT1) that was infected at three-time points. The characterized dominating metabolites were organic acids and their derivatives, organic oxygen compounds, lipids, and lipid-like molecules. Among the identified metabolites, shikimate, galactinol, trehalose, D-mannose, linolenic acid, dopamine, tyramine, and L-glutamine are precursors for the synthesis of many secondary defense metabolites Carbohydrate, as well as amino acid metabolic, pathways were revealed to be involved in plant defense responses and resistance strengthening.Conclusion: The increasing salicylic acid (SA) and jasmonic acid (JA) content enhanced interactions between JA synthesis/signaling gene, SA synthesis/receptor gene, raffinose/fructose/sucrose synthase gene, and cell wall-related genes all contribute to defense response in rice. The symptoms of rice after M. oryzae infection were significantly alleviated when treated with six identified metabolites, i.e., galactol, tyramine, L-glutamine, L-tryptophan, α-terpinene, and dopamine for 72 h exogenously. Therefore, these metabolites could be utilized as an optimal metabolic marker for M. oryzae defense.#These authors contributed equally to this work.
