Transmission of synthetic seed bacterial communities to radish seedlings: impact on microbiota assembly and plant phenotypeSeed synthetic community matters and its impact on seedling is strain- and not species-dependantRecommended by Sebastien Massart based on reviews by Cindy Morris, Sebastian Pfeilmeier and 1 anonymous reviewerEngineering plant microbiota can improve plant health and growth sustainably. Emergent approaches include rational Synthetic Communities (SynCom) design or soil amendments and specific agricultural practices to shift resident microbiota and to understand its impact (Moreira et al. 2023). In this context, the impact of seed microbiota on the early stages of plant development is becoming an essential topic in the study of plant–microbiota interactions. Behind the well-studied seed-borne pathogens, the seed microbiota can host many other commensal and beneficial organisms that have been neglected in the past. The study of Simonin et al. (2023) applies single isolates and synthetic communities (SynCom) on radish seeds to answer two key questions: what is the role of seed microbiota during the early stages of plant development? How can SynCom influence the seedling health and its microbiota? The study describes an elegant approach to cope with the variability of natural microbiota using SynCom following a gradient of complexity. Overall, the study highlighted a contrasted impact of the bacterial strains when applied in isolation or SynCom. The composition and complexity of the SynCom had also an impact on plant seedlings. Importantly, contrasting evolution from seeds to seedlings was observed for 3 strains of Pseudomonas fluorescens within the SynComs, underlining the importance of intra-species level diversity and precluding any generalization of results at species level.

Within-species variation in the gut microbiome of medaka (Oryzias latipes) is driven by the interaction of light intensity and genetic backgroundGetting closer to the host-microbe evolutionary relationshipRecommended by Konstantinos (Kostas) Kormas based on reviews by Laetitia Wilkins, Marco Basili and 1 anonymous reviewer
The issue of whether there is a clear and detectable relationship -either deterministic or stochastic- of fish gut microbiota with evolutionary processes is far from being resolved. Studies on fish microbiota are more perplexed as this animal group includes species both from wild and farmed populations (for food production, ornamental fish and animal models), with variable life cycles and ecophysiologies, and all these features expand the type of interactions to be studied. Based on this biological features variability, multiple methodological limitations, especially for the species with wild populations, are perhaps among of the central reasons for this knowledge gap. Therefore, experimental approaches, which can eliminate some of this variability, seem to be the best approach. The preprint by Evangelista et al. (2023) entitled "Within-species variation in the gut microbiome of medaka (Oryzias latipes) is driven by the interaction of light intensity and genetic background" is an example of such a targeted study with a freshwater fish species. Due to the paper's finely detailed experimental design, the interdisciplinary skills of the participating co-authors and exhaustive data analysis, this paper manages to draw solid and reproducible results and conclusions. This renders it not only an insightful contribution towards the more general host-microbe interactions in an evolutionary framework, but also a perfect example on how current and future relevant research should be conducted. I feel confident that this paper will assist other scientits of the field to move forward with their current working hypotheses but also to generate novel ones.
