Abstract


This study aimed to analyze the structural and functional diversity of microorganisms inhabiting Paulownia spp. leaves. Next Generation Sequencing (NGS) and Biolog EcoPlates were used to determine microbial diversity. The leaves of Paulownia spp. were taken from two different plantations. Among all the samples, P112_1 was the most abundantly colonized by plant growth promoting bacteria. Overall, the microbial community of the P. elongata × P. fortunei (PB) sample characterized the lowest metabolic activity with the utilization of the carbon sources. All communities used carbohydrates abundantly, whereas amines and amides were used the least. The differences observed may have been due to a variety of factors from composition of the chemicals in the leaf, to the soil type, to the climatic conditions.
