Use of mulberry-soybean intercropping in salt-alkali soil impacts the diversity of the soil bacterial community.

Li X, Sun M, Zhang H, Xu N, Sun G - Microb Biotechnol (2016)

Bottom Line: Most of Actinobacteria and Chloroflexi were found in intercropping samples, while Acidobacteria and Proteobacteria were present at a higher percentage in monoculture samples.The plant diversity of aboveground and microbial diversity of belowground was linked and soil pH seemed to influence the bacterial community.Finally, the specific plant species was the major factor that determined the bacterial community in the salt-alkali soils.

Hierarchical cluster analysis of 100 predominant bacterial communities among the four samples. The Y‐axis is the clustering of the most abundant OTUs (5% distance) in reads. The OTUs were ordered by genus. Sample communities were clustered based on complete linkage method. The colour intensity of scale indicates relative abundance of each OTU read. Relative abundance was defined as the number of sequences affiliated with that OTU divided by the total number of sequences per sample.

mbt212342-fig-0005: Hierarchical cluster analysis of 100 predominant bacterial communities among the four samples. The Y‐axis is the clustering of the most abundant OTUs (5% distance) in reads. The OTUs were ordered by genus. Sample communities were clustered based on complete linkage method. The colour intensity of scale indicates relative abundance of each OTU read. Relative abundance was defined as the number of sequences affiliated with that OTU divided by the total number of sequences per sample.

Mentions: Hierarchically clustered heatmap analysis, based on the microbial community profiles at the genus level, was used to identify the different composition of these four microbial community structures (Fig. 5). The MM and IM groups were separated from SM and IS groups, suggesting clear distinctions of microbial community structure between mulberry and soybean groups. This was supported by the principal component analysis (PCA) with the weighted Unifrac distance (Fig. 6). Overall, the two PCA axes explained 77.36% of the variation between the different communities. The PCA score plot revealed that the mulberry and soybean rhizosphere soils harboured characteristic bacterial communities. Mulberry samples (MM and IM) were clustered together and were well separated from that soybean samples (SM and IS), whereas there was a little distinction between SM and IM samples. These results suggested that plant species had the greatest affect on the bacterial communities in the soil used to support those plants.
