The paper develops a scalable genomic framework for programmable strain tagging in Sphingomonas using CRISPR-associated transposons and introduces a novel transposon mapping method for strain tracking.

The paper shows plant-associated Sphingomonas use two flagellar FliC variants to balance swimming and immune evasion by partitioning motility and colonization functions.

The study shows that field conditions override the growth-defense tradeoff in Arabidopsis thaliana by modulating ACD6 activity, unlike greenhouse conditions.

The paper introduces SmT, a spatial metatranscriptomics method to study host-microbe interactions in Arabidopsis thaliana, revealing microbial hotspots and spatial networks.

The paper combines shotgun sequencing and rDNA amplicon data to improve detection of microbe-microbe interaction networks in plant leaves by addressing compositionality issues in amplicon data.
