We investigated (i). the composition of soil bacterial communities in continuous monoculture and rotation in 3-cropping systems (continuous maize monoculture for 3 years, continuous peanut monoculture for 3 years, maize-peanutrotation), (ii). ifsoil bacterial communities in the rhizosphere were affected by the addition of chemical soil amendments (mixture of biochar and silicon powder) and biological soil amendments (Kuai-rui-song) in continuous monoculture peanut. The Analysis of the V4 16S rRNA gene region on the Illumina MiSeq platform, identified the changes in bacterial diversity and community structure. Although the composition of predominant taxa was similar in all 5-treatments, but there were few differences in the least-abundant phyla such as Synergistetes, Tenericutes, GAL15 and WS2. There were four unique phyla [Synergistetes, GAL15, WS2 and Kazan-3B-28] in peanut fields in continuous monoculture. Four phyla [Tenericutes, WS2, OP3 and FCPU426] were significantly different (p < 0.05) in the peanut monoculture field and in the maize-peanut rotation field. Continuous monoculture with peanut had the highest bacterial community richness, as indicated by high Chao index and Ace index. In maize-peanut rotation, the rhizosphere bacteria belongedto 500 genera. Among the bacteria, Bradyrhizobium, Rhodospirillum, Burkholderia, CandidatusKoribacter, Candidatus, Solibacterand Koribacteraceaewere more frequent. Although there was no improvement in bacterial diversity at the generic level, but the addition of soil amendments slightly altered the bacterial diversity than in peanut monoculture andthe addition of biological soil amendmentwas slightly better than the chemical additive. © 2017, International Allelopathy Foundation.

... The other abundant keystone species, such as the genus Planctomicrobium, genus Bdellovibrio and family Sphingomonadaceae in H. verticillata rhizosphere; and the genus Lysobacter, family Anaerolineaceae and genus Geoalkalibacter in E. canadensis rhizosphere (Table S6; Fig. 5), also posed potentials for promoting plant growth and/or tolerating metal contaminants (Huang et al., 2017;Meng et al., 2019;Miura et al., 2019;Wei et al., 2019;Xiao et al., 2019;Zhang et al., 2019b). Most of these rhizosphere keystone species were metabolic generalists with vital ecological functions in bacterial communities (Fan et al., 2018). ...
