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.

mbt212342-fig-0003: Relative abundance of bacterial phyla for each soil library. MM, mulberry monoculture; IM, intercropping mulberry; SM, soybean monoculture; IS, intercropping soybean.

Mentions: The 65 926 classifiable sequences were affiliated with 11 bacterial phyla (Fig. 2). The groups accounted for 96% of all sequences, and a few sequences (< 1%) could not be shown (e.g. Spirochaetes). The dominant phyla across all samples were Proteobacteria, Acidobacteria, Actinobacteria, Chloroflexi, Bacteroidetes, Planctomycetes and Gemmatimonadetes, representing 24.1%, 18.9%, 17.6%, 13.3%, 10.0%, 4.6% and 3.6%, respectively, of all sequences that were classified below the domain level. These dominant bacterial phyla were found in all samples (Fig. 3). Other sequences belonged to Verrucomicrobia, Nitrospirae, Armatimonadetes and unclassified bacteria of ‘Candidatedivision TM7’, and they were always found in very low proportions (< 2%).
