Fig. 2From: Comparative analysis of the endophytic bacteria inhabiting the phyllosphere of aquatic fern Azolla species by high-throughput sequencingPCoA analysis of endophytic bacterial communities in five species of Azolla. Notes: The analysis method is based on Bray Curtis-based principal coordinate analysis (PCoA) using ade4 and ggplot2 packages of R (v3.6.0) software. Points of different colors or shapes represent different grouping situations, and the scale of the horizontal and vertical axes is a relative distance. PC1, PC2 represent the suspected influencing factors of the microbial composition of the two groups, which need to be combined with the sample characteristic informationBack to article page
