Fig. 3. Principal component analysis (PCA) and non-metric
multi-dimensional scaling (NMDS) plots of the bacterial community in the
rubber phyllosphere
a. PCA plot of the bacterial community in the rubber phyllosphere. PC1
contributed the most significantly (91.93%), whereas PC2 explained just
4% of the variation.
The DZ and BS samples (closer geographically close) are clustered
together in the PCA, while the WN and WZS samples (farther
geographically) can be clearly distinguished from them. There are
significant differences in bacterial communities among the different
regions.
b. NMDS of the bacterial community in the rubber phyllosphere. Except
for WZS_3 samples, samples with a closer geographical distance or
similar climate type had higher composition similarity and tended to
cluster together.
