Happy to share our latest work digging a bit more into what makes the the core microbiota of photosynthetic organisms convergent (or not!). Work performed @lipme-toulouse.bsky.social @cnrs.fr, in collaboration with @guan06rui.bsky.social @quadraminstitute.bsky.social tinyurl.com/3e958dt6 (1/10)

tinyurl.comEnvironmental factors and microbe-microbe interactions drive the structure of the core microbiota of terrestrial microalgaePlants and other photosynthetic organisms interact with their environment and surrounding microbiota through specialized associations. A global core microbiota has been proposed at high taxonomic levels, such as the order level. However, it remains unclear which environmental factors and how microbe-microbe interactions drive variation of this core microbiota at lower taxonomic resolution. Here, we leveraged the environmental diversity of 141 sites across the southwest of France to characterize algal populations, and their associated bacterial and fungal microbiota. We then performed a meta-analysis, combining these data with published datasets to formally identify the global core microbiota of terrestrial photosynthetic organisms, which comprises seven bacterial and five fungal orders. We next investigated diversity within this core microbiota and the environmental drivers shaping site-specific community composition. While environmental factors have a low impact on the total relative abundance of core orders, the core microbiota at the ASV-level is impacted by climatic factors, edaphic factors, and plant community descriptors. Using interaction network analysis, we finally explored how microbe-microbe interactions contribute to the assembly of stable core communities. Our results show that core ASVs occupy central positions in algal-associated microbial networks and that distinct core orders drive site-specific variation in core microbiota structure. Together, these findings highlight the importance of both environmental context and microbial interactions in shaping the composition and stability of the core microbiota associated with photosynthetic organisms. ### Competing Interest Statement The authors have declared no competing interest.

Our work shows that ASV-balancing across environments allows a stable core microbiota at high taxonomic levels, which probably retain their functionality across environments. Future work will focus on exploring these functions, so stay tuned! (9/10)

But, how does the core microbiota structure as a community? Network analysis showed that core groups are more connected among themselves and that negative interactions between fungal and bacterial kingdoms are more prevalent in core nodes.(6/10)

Paloma Durán
@paduba.bsky.social

And is this the same across environments? No! Actually, despite stability of core communities, the environment also determines the core community network structure.(8/10)

...when using our algal survey to look at deeper taxonomic levels, we saw that not a single ASV is found everywhere. So, what drives this variability? Of course, environmental factors! (climatic conditions, soil properties and surrounding plant communities). (5/10)

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...

doi.orgHorizontal acquisition of nicotine catabolism gene cluster enhances Arthrobacter fitness within tobacco root microbiota - MicrobiomeBackground 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
