Comparative Analyses of Phyllosphere Bacterial Communities and Metabolomes in Newly Developed Needles of Cunninghamia lanceolata (Lamb.) Hook. at Four Stages of Stand Growth.

ABSTRACT: Host-plant-associated bacteria affect the growth, vigor, and nutrient availability of the host plant. However, phyllosphere bacteria have received less research attention and their functions remain elusive, especially in forest ecosystems. In this study, we collected newly developed needles from sapling (age 5 years), juvenile (15 years), mature (25 years), and overmature (35 years) stands of Chinese fir [Cunninghamia lanceolata (Lamb.) Hook]. We analyzed changes in phyllosphere bacterial communities, their functional genes, and metabolic activity among different stand ages. The results showed that phyllosphere bacterial communities changed, both in relative abundance and in composition, with an increase in stand age. Community abundance predominantly changed in the orders Campyloba
