ABSTRACT Plants host diverse microbial communities essential for nutrient acquisition, growth, and responses to biotic abiotic stresses. Despite their importance, the variation stability of these during forest succession remain poorly understood. This study investigated in Pinus massoniana forests at different stand ages (12, 22, 30, 40 years). Results showed that phyllosphere roots P. harbor communities, which shift dynamically with aging. Bacterial species diversity consistently surpassed fungal across all habitats. Forest aging significantly influenced alpha soil microbes, whereas root‐associated remained stable. Co‐occurrence network analysis revealed bacterial formed more complex networks than exhibited greater stability. Functional annotation confirmed were functionally stable, predominantly involving metabolic processes. In contrast, endophytes dominated fungi, while ectomycorrhizal fungi prevalent root communities. Environmental factors, including total nitrogen, phosphorus, available potassium, pH, emerged as key drivers dynamics. These findings provide novel insights into differing aging, highlighting critical role ecological niches shaping
