| 1 | Genomic analyses of metal resistance genes in three plant growth promoting bacteria of legume plants in Northwest mine tailings, China显示文摘To better understand the diversity of metal resistance genetic determinant from microbes that survived at metal tailings in northwest of China, a highly elevated level of heavy metal containing region, genomic analyses was conducted using genome sequence of three native metal-resistant plant growth promoting bacteria(PGPB). It shows that: Mesorhizobium amorphae CCNWGS0123 contains metal transporters from P-type ATPase, CDF(Cation Diffusion Facilitator), Hup E/Ure J and CHR(chromate ion transporter) family involved in copper, zinc, nickel as well as chromate resistance and homeostasis. Meanwhile, the putative Cop A/Cue O system is expected to mediate copper resistance in Sinorhizobium meliloti CCNWSX0020 while Znt A transporter, assisted with putative Czc D, determines zinc tolerance in Agrobacterium tumefaciens CCNWGS0286. The greenhouse experiment provides the consistent evidence of the plant growth promoting effects of these microbes on their hosts by nitrogen fixation and/or indoleacetic acid(IAA) secretion,indicating a potential in-site phytoremediation usage in the mining tailing regions of China. | Pin Xie Xiuli Hao Martin Herzberg Yantao Luo Dietrich H.Nies Gehong Wei | 2015 | Journal of Environmental Sciences2015，27，1： | 5 |

| 3 | Inter-phylum negative interactions affect soil bacterial community dynamics and functions during soybean development under long-term nitrogen fertilization显示文摘Understanding interspecies interactions is essential to predict the response of microbial communities to exogenous perturbation.Herein,rhizospheric and bulk soils were collected from five developmental stages of soybean,which grew in soils receiving 16-year nitrogen inputs.Bacterial communities and functional profiles were examined using high-throughput sequencing and quantitative PCR,respectively.The objective of this study was to identify the key bacterial interactions that influenced community dynamics and functions.We found that the stages of soybean development outcompeted nitrogen fertilization management in shaping bacterial community structure,while fertilization treatments significantly shaped the abundance distribution of nitrogen functional genes.Temporal variations in bacterial abundances increased in bulk soils,especially at the stage of soybean branching,which helps to infer underlying negative interspecies interactions.Members of Cyanobacteria and Actinobacteria actively engaged in inter-phylum negative interactions in bulk soils and soybean rhizosphere,respectively.Furthermore,the negative interactions between nitrogen-fixing functional groups and the reduction of nifH gene abundance were coupled during soybean development,which may help to explain the linkages between population dynamics and functions.Overall,these findings highlight the importance of inter-phylum negative interactions in shaping the correlation patterns of bacterial communities and in determining soil functional potential. | Chunfang Zhang Shuo Jiao Duntao Shu Gehong Wei | 2021 | Stress Biology2021，1，1： | 1 |

| 5 | Regulation of root secondary metabolites by partial root-associated microbiotas under the shaping of licorice ecotypic differentiation in northwest China显示文摘Interactions between plant hosts and their microbiotas are becoming increasingly evident,while the effects of plant communities on microbial communities in different geographic environments are poorly understood.Here,the differentiation of licorice plant ecotypes and the distribution of rootassociated microbiotas were investigated across five sampling sites in northwest China.The interactions between the environment,plant and microbial communities,and their effects on licorice root secondary metabolites,were elucidated.The plant community was clearly differentiated into distinct ecotypes based on genotyping-by-sequencing and was primarily driven by geographic distance and available soil nitrogen.The bulk soil and rootassociated microbiotas(rhizosphere soil and root endosphere)partially correlated with plant community,but all were significantly discriminated by plant clade.Moreover,these microbiotas were explained to different extents by distinct combinations of environment,geography,and plant community.Similarly,three structural equation models showed that licorice root secondary metabolites were complicatedly modulated by multiple abiotic and biotic factors,and were mostly explained by these factors in the rhizosphere model.Collectively,the results provide novel insights into the role of environment–plant–microbiota interactions in regulating root secondary metabolites.That should be accounted for when selecting appropriate licorice planting sites and management measures. | Yang Liu Hao Wang Ziheng Peng Da Li Weimin Chen Shuo Jiao Gehong Wei | 2021 | Journal of Integrative Plant Biology2021，63，12： | 1 |

| 9 | Soil phosphorus determines the distinct assembly strategies for abundant and rare bacterial communities during successional reforestation显示文摘Uncovering the mechanisms underlying the diversity patterns of abundant and rare species is crucial for terrestrial biodiversity maintenance.However,the response of abundant and rare community assembly to ecological succession has not been explored,particularly considering soil profiles.Here 300 soil samples were collected from reforestation ecosystems from depths of up to 300 cm and horizontal distances of 30–90 cm from a tree.We revealed that soil phosphorus not only affected alpha diversity and community structure,but also mediated the balance of stochastic and deterministic processes for abundant and rare sub-communities,which exhibited contrasting assembly strategies.The abundant sub-community changed from variable selection to stochasticity with the increase of phosphorus,while the rare sub-community shifted from homogeneous selection to stochasticity.Dispersal limitation was the main assembly process in the abundant sub-community,while the rare sub-community was governed primarily by homogeneous selection.Moreover,the relative influence of deterministic processes increased with succession for both sub-communities.At the scale of a single tree,stochastic processes increased with soil depth in rare sub-community,while deterministic processes increased with the radius from a single tree in the abundant subcommunity.Overall,our results highlight the importance of the soil phosphorus-driven assembly process in understanding the re-assembly and maintenance of soil bacterial diversity. | Ziheng Peng Zhifeng Wang Yu Liu Tongyao Yang Weimin Chen Gehong Wei Shuo Jiao | 2021 | Soil Ecology Letters2021，3，4： | 1 |
| 10 | Effects of cowpea(Vigna unguiculata) root mucilage on microbial community response and capacity for phenanthrene remediation显示文摘Biodegradation of polycyclic aromatic hydrocarbons(PAHs) is normally limited by their low solubility and poor bioavailability. Prior research suggests that biosurfactants are synthesized as intermediates during the production of mucilage at the root tip. To date the effects of mucilage on PAH degradation and microbial community response have not been directly examined. To address this question, our research compared 3 cowpea breeding lines(Vigna unguiculata) that differed in mucilage production for their effects on phenanthrene(PHE) degradation in soil. The High Performance Liquid Chromatography results indicated that the highest PHE degradation rate was achieved in soils planted with mucilage producing cowpea line C1, inoculated with Bradyrhizobium, leading to 91.6% PHE disappearance in 5 weeks. In root printing tests, strings treated with mucilage and bacteria produced larger clearing zones than those produced on mucilage treated strings with no bacteria or bacteria inoculated strings. Experiments with14C-PHE and purified mucilage in soil slurry confirmed that the root mucilage significantly enhanced PHE mineralization(82.7%), which is 12% more than the control treatment without mucilage. The profiles of the PHE degraders generated by Denaturing gradient gel electrophoresis suggested that cowpea C1, producing a high amount of root mucilage, selectively enriched the PHE degrading bacteria population in rhizosphere. These findings indicate that root mucilage may play a significant role in enhancing PHE degradation and suggests that differences in mucilage production may be an important criterion for selection of the best plant species for use in phytoremediation of PAH contaminated soils. | Ran Sun Richard W.Belcher Jianqiang Liang Li Wang Brian Thater David E.Crowley Gehong Wei | 2015 | Journal of Environmental Sciences2015，27，7： | 1 |
| 11 | A hybrid artificial photosynthesis system with molecular catalysts covalently linked onto TiO2 as electron relay for efficient photocatalytic hydrogen evolution显示文摘Efficient charge carrier transfer from light harvesters to catalysts greatly determines the photocatalytic activity in an artificial photosynthesis(AP) system for solar hydrogen evolution.In this study,an AP system composed of xanthene dye as light harvester and cobaloxime molecular complex as catalyst,with TiO2 as electron relay,was designed for photocatalytic hydrogen evolution under visible light(λ>420 nm).It was demonstrated that with cobaloxime molecule covalently linked onto the TiO2 electron relay,the resulting hybrid AP system exhibited much increased photocatalytic activity as compared to that without TiO2.The greatly increased photocatalytic activity should be due to the efficient electron transfer from xanthene dye as light harvester and cobaloxime molecular complex as catalyst,shuttled by the TiO2 electron relay,for the following water reduction reaction.The present study demonstrates a facile and feasible strategy to guide the design of high performance AP systems through the electron relay shuttled and promoted cha rge transfer process. | Jie Zhang Gehong Zhang Jing Zhang | 2020 | Journal of Materials Science & Technology2020，47，15： | 0 |
