So excited to share our new study about nicotine-mediated tobacco root-microbiota interactions, spearheaded by Tomohisa! Nicotine is a neurotoxin for insects, but for Arthrobacter, it works as a nutritional source that provides a competitive advantage. doi.org/10.1186/s401...

Horizontal acquisition of nicotine catabolism gene cluster enhances Arthrobacter fitness within tobacco root microbiota - Microbiome

Background Plant roots are hotspots for interactions with soil microbes, where a characteristic bacterial community structure is formed. Plant specialized metabolites often play pivotal roles in this assembly process. However, the molecular basis underlying root microbiota responses to these bioactive compounds, and how such metabolic interactions shape the assembly of host-specific root microbiota, remain largely unknown. Nicotine is a toxic alkaloid predominantly produced by the genus Nicotiana, and the genus Arthrobacter is known as one of the nicotine-degrading bacteria in the tobacco root microbiota. In this study, we used the tobacco–Arthrobacter interaction system as a model and integrated comparative genomics and experimental genetic manipulation assays to uncover the role of bacterial catabolism capacity for host specialized metabolites in shaping host-specific root microbiota. Results Nicotine catabolism genes are uniquely found in the Arthrobacter strains derived from nicotine-containing environments, and this restricted gene distribution is driven by a plasmid-mediated horizontal gene transfer. To assess the ecological consequences of this genomic adaptation in Arthrobacter fitness in tobacco roots, we characterized the nicotine utilization ability of Arthrobacter and conducted adaptation assays under in planta conditions using genetically manipulated Arthrobacter strains and tobacco mutants impaired in nicotine catabolism and biosynthesis, respectively. Nicotine improves Arthrobacter colonization of tobacco roots through a catabolism-dependent mechanism. Bacterial community analysis using a synthetic community approach further demonstrated that this metabolic adaptation enhances Arthrobacter fitness within tobacco root microbiota. Conclusions Our findings illustrated that bacterial catabolic capacity toward host-derived plant specialized metabolites is key for successful root colonization. This metabolic adaptation is driven by plasmid-mediated horizontal gene transfer and ultimately shapes the structure of the root microbiota community. Video Abstract

Together with Mathieu Hanemian, we're searching for an undergrand student (Master or Erasmus internship, final-year engineering student) to explore the effect of intercropping on the soil microbiota. If this sounds interesting to you, please reach our with your CV and a motivation letter!

Internship objectives The main objective of the internship will be to determine how intercropping modifies the composition and functions of the rhizosphere microbiome associated with each cultivated species, in comparison with sole crops. The intern will also seek to identify common microbial signatures across different intercropping systems in order to highlight potential general mechanisms associated with plant diversification. Particular attention will be paid to the functions potentially associated with the observed changes, based on the identification of microbial taxa and targeted qPCR analyses. The intern will participate in the entire analytical workflow, from molecular biology procedures (DNA extraction, PCR, preparation of sequencing libraries) to bioinformatic data processing, statistical analyses using R, and biological interpretation of the results. The results will contribute to identifying the microbial mechanisms that may explain the agronomic benefits of intercropping and may help guide the development of new agroecological practices.

Back to our great invited speakers! Marie Invernizzi (LIPME, Toulouse 🇫🇷) takes the stage with “Deciphering the Molecular Basis of Plant Responses to Competition in Arabidopsis thaliana” 🌿⚔️ Plants competing like in a Pokémon battle — and we’re learning their secrets! #UPSCSymposium #PlantBiology

Marie Invernizzi stands at a podium in a bright conference room, gesturing toward a large projected slide. The slide is titled “Competition as a boxing match… or a Pokémon battle!” and features a screenshot styled after a classic Pokémon video game battle screen. In it, Arabidopsis thaliana (lv. 42) faces off against Poa annua (lv. 17), with the battle prompt reading “P. annua wants to battle! What will A. thaliana do?” The in-game action buttons — Fight, Ignore, Wait, and Run — are visible. To the right of the image, the slide lists the plant’s strategic options: “Put KO the opponent and avoid KO: Suppress / Tolerate.” A creative and playful way to frame interspecific plant competition research.​​​​​​​​​​​​​​​​

Really proud of this work led by Ruben Eichfeld! We show how a CBM domain gain/loss can rewire fungal chitinases, turning them from antifungal enzymes into immune-suppressing effectors that support plant symbiosis. www.nature.com/articles/s41...

Domain gain or loss in a fungal chitinase enables specialization towards antagonism or immune suppression - Nature Communications

Gain or loss of a particular domain contributes to functional specialization of a conserved chitinase in beneficial root endophyte towards microbial antagonism or host immune suppression.
