Excited that this is finally out, led by @jhuisman.bsky.social with Jeff Gore, combining experiments, theory and natural microbiome data! As salinity rises, diversity and individual species growth rates fall, yet community's overall growth stays robust: faster growers take over and keep it going.

Have you ever wondered what increasing environmental stress will do to microbial communities? In our new preprint, @martinadalbello.bsky.social, Jeff Gore and I studied the impact of salinity on microbial community composition and function. 🧵 (1/5) www.biorxiv.org/content/10.1...

In the literature of domestication and microbiomes there seems to be the expectation that: domestication should lead to the loss of microbiome diversity and host-control. Alejandra Hernandez-Teran and I were both skeptical of both, so we decided to see what we know so far (1/6) shorturl.at/FHY9H

Plant domestication does not reduce diversity in root microbiomes

Domestication has profoundly shaped human civilization and the genetic makeup of numerous plant and animal species. While the effects of plant domestication at the genetic and phenotypic levels are well-documented, its impact on plant microbiome remains less understood. Root microbiomes play crucial roles in nutrient acquisition, pathogen defense, and biotic stress tolerance, yet the influence of domestication on their diversity and assembly is still debated. Two primary hypotheses have been proposed: 1) the reduction in microbial diversity resulting from the domestication process, and 2) the diminished ability of host plants to control their microbiomes. To evaluate these hypotheses, we conducted a meta-analysis of multiple crops, comparing the root microbiomes of domesticated plants and their wild relatives. Our results indicate that the effects of domestication are species-specific and context-dependent, with most domesticated plants exhibiting increased microbial diversity and more structured communities, while others show no significant change. Overall, this study provides evidence that plant domestication does not lead to a uniform reduction in microbial diversity or a consistently diminished ability of plants to influence their microbiomes. Based on these findings, we discuss new perspectives and the need for future studies incorporating native soils and host genetic variation in such experiments, analyzing not only diversity but also microbiome function, and considering how root morphology might affect microbiome recruitment. Finally, we highlight the need for research on the potential adaptive or maladaptive consequences that introgression between wild and domesticated plants could have from a microbiome perspective. ### Competing Interest Statement The authors have declared no competing interest.
