Article Abstract

Proteins are integral components of root exudates that mediate plant-microbe interactions, nutrient mobilization, and stress responses. Despite their importance, our understanding of their composition, regulation, and function is limited. Here, we summarize recent advances on root-exuded proteins, highlight pivotal outstanding questions, and propose future research directions.

Background: Plant roots release root exudates to attract microbes that form root communities, which in turn promote plant health and growth. Root community assembly arises from millions of interactions between microbes and the plant, leading to robust and stable microbial networks. To manage the complexity of natural root microbiomes for research purposes, scientists have developed reductionist approaches using synthetic microbial inocula (SynComs).

Seven plant growth-promoting bacteria (PGPB) were isolated from extracts of surface-sterilized Sedum alfredii Hance. Among the seven isolates, the strain SaRB5 identified as Stenotrophomonas maltophilia through 16S rDNA sequence analysis, exhibited highest levels of heavy metal resistance and plant growth-promoting traits. SaRB5 tolerated high concentrations of cadmium (Cd) (1.

Inter-laboratory replicability is crucial yet challenging in microbiome research. Leveraging microbiomes to promote soil health and plant growth requires understanding underlying molecular mechanisms using reproducible experimental systems. In a global collaborative effort involving five laboratories, we aimed to help advance reproducibility in microbiome studies by testing our ability to replicate synthetic community assembly experiments.

The increasing demand for sustainable agricultural practices has driven a renewed interest in plant-microbiome interactions as a basis for the next "green revolution." Central to these interactions are root-derived metabolites that act as mediators of microbial recruitment and function. Plants exude a chemically diverse array of compounds that influence the assembly, composition, and stability of the root microbiome.
