Increased antibiotic resistance gene abundance linked to intensive bacterial competition in the phyllosphere across an elevational gradient.

ABSTRACT: Antibiotic resistance genes (ARGs) are ancient and widespread in natural habitats, providing survival advantages for microbiomes under challenging conditions. In mountain ecosystems, phyllosphere bacterial communities face multiple stress conditions, and the elevational gradients of mountains represent crucial environmental gradients for studying biodiversity distribution patterns. However, the distribution patterns of ARGs in the phyllosphere along elevational gradients, and their correlation with bacterial community structures, remain poorly understood. Here, we applied metagenomic analyses to investigate the abundance and diversity of ARGs in 88 phyllosphere samples collected from Mount Tianmu, a national natural reserve. Our results showed that the abundance of ARGs in the phyllosphere
