Widespread horizontal gene transfer between plants and their microbiota

The paper identifies 180 horizontally transferred genes between plants and their microbiota, showing functional complementarity and suggesting gene transfer shapes host-microbe interactions.

Fine-scale diversity of microbial communities due to satellite niches in boom-and-bust environments

The paper uses a consumer-resource model to show that microbial strains can coexist in boom-and-bust environments by differentiating on Monod parameters, resulting in 1-3 strains coexisting despite theoretical limits.

Root meristem shaping via brassinosteroid-controlled cell geometry

This study shows brassinosteroid signaling modulates cell geometry and growth anisotropy in root meristems, shaping root form without affecting cell volume.

Complementary resource preferences spontaneously emerge in diauxic microbial communities

This study develops a model of diauxic microbial communities and finds that complementary resource preferences emerge spontaneously during community assembly.

Optimal BR signalling is required for adequate cell wall orientation in the Arabidopsis root meristem

This study shows that optimal brassinosteroid (BR) signaling is necessary for proper cell wall orientation in the Arabidopsis root meristem, with defects linked to altered cortical division zone localization.

Auxin requirements for a meristematic state in roots depend on a dual brassinosteroid function

This study shows that brassinosteroids (BR) have a dual role in regulating auxin to maintain root meristem function, with BR promoting auxin biosynthesis while repressing its transcriptional output.

Multistability and regime shifts in microbial communities explained by competition for essential nutrients

This study explains multistability and regime shifts in microbial communities through a resource-explicit model and game-theoretical methods, showing that nutrient stoichiometry and supply balance influence stability and diversity.
