Agaves are plants native to North America that sustain life in arid and semiarid ecosystems. Previous studies revealed cultivated of Agave tequilana had lower microbial diversity functionality than wild species. Here, we tested if synthetic communities (syncoms), based on hubs or taxa with enriched functions, could increase diversity, plant health, productivity A. tequilana. We applied 10 syncoms the phyllospheres 6-month-old field monitored their development for 2 years. Amplicon sequencing 16S-rRNA-V4 ITS2 inoculated played a negligible minor role assembly prokaryotic eukaryotic phyllospheric associated tequilana, respectively. However, hubs, particularly those observed phyllosphere salmiana (PFCS), promoted higher alpha diversity.

Abstract Background Microbe-microbe interactions between members of the plant rhizosphere are important but remain poorly understood. A more comprehensive understanding molecular mechanisms used by microbes to cooperate, compete, and persist has been challenging because complexity natural ecosystems limited control over environmental factors. One strategy address this challenge relies on studying in a progressive manner, first building detailed relatively simple subsets community then achieving high predictive power through combining different blocks (e.g., hosts, members) for environments. Herein, we coupled reductionist approach with high-resolution mass spectrometry-based metaproteomics study driving assembly, adaptation, functionality defined ten taxonomically diverse bacterial Populus deltoides co-cultured either complex or medium.
