Effects of Betaine Aldehyde Dehydrogenase-Transgenic Soybean on Phosphatase Activities and Rhizospheric Bacterial Community of the Saline-Alkali Soil

Figure 7

PCoA analysis of the bacteria of each sample at the 97% similarity of sequences based on UniFrac method. Principal component 1 and principal component 2 explained 14.8% and 14.4% of the total variations. Note: R1–R5 and S1–S5 mean 25 d, 50 d, 75 d, 100 d, and 125 d of STRS and NH35 of soybean at different growth stages.
