Rare bacterial subcommunity drives nutrient cycling in phyllosphere habitat of evergreen conifers.

ABSTRACT: Phyllosphere bacteria are crucial for pathogen resistance, stress tolerance, and productivity maintenance of host plants and further have potential effects on ecosystem functions. However, whether and how assembly patterns of both abundant and rare subcommunities changed across needle age cohorts, and their relative contributions to nutrient cycling in phyllosphere habitat of evergreen conifers are still unclear. Here, we examined both phyllosphere abundant and rare bacterial subcommunities in three needle age cohorts of the representative evergreen conifers in mixed broadleaved-Korean pine forests throughout Northeast China. We found that dispersal limitation and ecological drift dominated abundant and rare subcommunities, respectively. Deterministic assembly gradually increased with need
