Bacterial community composition of wheat aboveground compartments correlates with yield during the reproductive phase

The developmental stage significantly influences crop-associated bacterial communities, but the relative importance of bacterial communities in different compartments to crop yields across various stages is still not well understood. This study reveals that belowground bacterial communities during the vegetative phase are significantly correlated with crop yields. Notably, during the reproductive phase, the composition of aboveground bacterial communities was significantly correlated with crop yields. During this phase, the complexity and enriched keystone species within the aboveground co-occurrence network underscore their role in boosting crop production. These results provide a foundation for developing microbiome-based products that are phase-specific and promote sustainable agricultural practices.
