Abstract:

Altitudinal gradients strongly influence vegetation biodiversity, but the microbial composition variation still poorly understands. Therefore, we set an experiment on studying soil bacterial diversity and community along six different altitudinal gradients in Changbai Mountains by using Illumina high through sequencing technology. The results showed that soil physicochemical properties changed significantly between six different altitudinal gradients. The Soil bacterial alpha diversities of 1690 m and 1800 m were highest than other gradients. Principle coordination analysis (PCoA) indicated that soil bacterial beta diversity significantly changed in six different altitudinal gradients. Moreover, Acidobacteriaand Proteobacteria and Actinobacteria did not significantly change between six different altitudes; but, the Chloroflexi and Bacteroidetes and Gemmatimonadetes were significantly higher at A and B altitudes. The responses of bacterial alpha diversity were mostly associated with soil moisture and NO3- and available potassium (AK), whereas the pH and soil moisture were the key factors affect the bacterial composition structures. Overall, our results suggest that soil bacterial diversity and composition of Deyeuxia angustifolia population were affected by different soil characteristics and would indicate the D. angustifolia population of different altitudes affected by different soil characteristics.
