Oxidative stress and NF-κB signaling are involved in LPS induced pulmonary dysplasia in chick embryos

Yun Long, Guang Wang, Ke Li, Zongyi Zhang, Ping Zhang, Jing Zhang, Xiaotan Zhang, Yongping Bao, Xuesong Yang & Pengcheng Wang
Inflammation or dysbacteriosis-derived lipopolysaccharides (LPS) adversely influence the embryonic development of respiratory system. However, the precise pathological mechanisms still remain to be elucidated. In this study, we demonstrated that LPS exposure caused lung maldevelopment in chick embryos, including higher embryo mortality, increased thickness of alveolar gas exchange zone, and accumulation of PAS+ immature pulmonary cells, accompanied with reduced expression of alveolar epithelial cell markers and lamellar body count. Upon LPS exposure, pulmonary cell proliferation was...

Whole-Genome-Sequencing characterization of bloodstream infection-causing hypervirulent Klebsiella pneumoniae of capsular serotype K2 and ST374

Xiaoli Wang, Yingzhou Xie, Gang Li, Jialin Liu, Xiaobin Li, Lijun Tian, Jingyong Sun, Hong-Yu Ou & Hongping Qu
Hypervirulent K. pneumoniae variants (hvKP) have been increasingly reported worldwide, causing metastasis of severe infections such as liver abscesses and bacteremia. The capsular serotype K2 hvKP strains show diverse multi-locus sequence types (MLSTs), but with limited genetics and virulence information. In this study, we report a hypermucoviscous K. pneumoniae strain, RJF293, isolated from a human bloodstream sample in a Chinese hospital. It caused a metastatic infection and fatal septic shock in a critical patient. The...

Data from: Phagocytic intracellular digestion in amphioxus (Branchiostoma)

Chunpeng He, Tingyu Han, Xin Liao, Yuxin Zhou, Xiuqiang Wang, Rui Guan, Tian Tian, Yixin Li, Changwei Bi, Na Lu, Ziyi He, Bing Hu, Qiang Zhou, Yue Hu, Zuhong Lu & Jun-Yuan Chen
The digestive methods employed by amphioxus (Branchiostoma)—both intracellular phagocytic digestion and extracellular digestion—have been discussed since 1937. Recent studies also show that epithelial cells lining the Branchiostoma digestive tract can express many immune genes. Here, in Branchiostoma belcheri, using a special tissue fixation method, we show that some epithelial cells, especially those lining the large diverticulum protruding from the gut tube, phagocytise food particles directly, and Branchiostoma can rely on this kind of phagocytic intracellular...

Data from: Local root growth and death are mediated by contrasts in nutrient availability and root quantity between soil patches

Peng Wang, Yan Yang, Pu Mou, Qingzhou Zhao & Yunbin Li
Plants are thought to be able to regulate local root growth according to its overall nutrient status as well as nutrient contents in a local substrate patch. Therefore, root plastic responses to environmental changes are likely co-determined by local responses of root modules and systematic control of the whole plant. Recent studies showed that the contrast in nutrient availability between different patches could significantly influence the growth and death of local roots. In this study,...

Data from: Reconciling multiple impacts of nitrogen enrichment on soil carbon: plant, microbial, and geochemical controls

Chenglong Ye, Dima Chen, Steven J. Hall, Shang Pan, Xuebin Yan, Tongshuo Bai, Hui Guo, Yi Zhang, Yongfei Bai & Shuijin Hu
Impacts of reactive nitrogen (N) inputs on ecosystem carbon (C) dynamics are highly variable, and the underlying mechanisms remain unclear. Here, we proposed a new conceptual framework that integrates plant, microbial, and geochemical mechanisms to reconcile diverse and contrasting impacts of N on soil C. This framework was tested using long-term N enrichment and acid addition experiments in a Mongolian steppe grassland. Distinct mechanisms could explain effects of N on particulate and mineral-associated soil C...

1. Advances in information technology are increasing the use of radar as a tool to investigate and monitor bird migration movements. We set up a field campaign to compare and validate outputs from different radar systems. 2. Here we compare the pattern of nocturnal bird migration movements recorded by four different radar systems at a site in southern Sweden. Within the range of the weather radar (WR) Ängelholm, we operated a “BirdScan” (BS) dedicated bird...

Expression of circular RNAs during C2C12 myoblast differentiation and prediction of coding potential based on the number of open reading frames and N6-methyladenosine motifs

Rui Chen, Ting Jiang, Si Lei, Yanling She, Huacai Shi, Shanyao Zhou, Jun Ou & Yulin Liu
The importance of circular RNAs (circRNAs) as regulators of muscle development and muscle-associated disorders is becoming increasingly apparent. To explore potential regulators of muscle differentiation, we determined the expression profiles of circRNAs of skeletal muscle C2C12 myoblasts and myotubes using microarray analysis. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses were performed to explore circRNA functions. We also established competing endogenous RNA (ceRNA) networks using bioinformatics methods and predicted the coding...

Data from: Examining community stability in the face of mass extinction in communities of digital organisms

Tian-Tong Luo, Lise Heier, Zaki Ahmad Khan, Faraz Hasan, Trond Reitan, , Zi-Xuan Xie, Jian-Long Zhu & Gabriel Yedid
Digital evolution is a computer-based instantiation of Darwinian evolution in which short self-replicating computer programs compete, mutate, and evolve. It is an excellent platform for addressing topics in long-term evolution and paleobiology, such as mass extinction and recovery, with experimental evolutionary approaches. We evolved model communities with ecological interdependence among community members, which were subjected to two principal types of mass extinction: a pulse extinction that killed randomly, and a selective press extinction involving an...

Autophagy enhances the replication of Peste des petits ruminants virus and inhibits caspase-dependent apoptosis in vitro

Bo Yang, Qinghong Xue, Xuefeng Qi, Xueping Wang, Peilong Jia, Shuying Chen, Ting Wang, Tianxia Xue & Jingyu Wang
Peste des petits ruminants (PPR) is an acute and highly contagious disease in small ruminants that causes significant economic losses in developing countries. An increasing number of studies have demonstrated that both autophagy and apoptosis are important cellular mechanisms for maintaining homeostasis, and they participate in the host response to pathogens. However, the crosstalk between apoptosis and autophagy in host cells during PPRV infection has not been clarified. In this study, autophagy was induced upon...

Data from: Invasive plants differentially affect soil biota through litter and rhizosphere pathways: a meta-analysis

Pei Zhang, Bo LI, Jihua Wu & Shuijin Hu
Invasive plants affect soil biota through litter and rhizosphere inputs, but the direction and magnitude of these effects are variable. We conducted a meta-analysis to examine the different effects of litter and rhizosphere of invasive plants on soil communities and nutrient cycling. Our results showed that invasive plants increased bacterial biomass by 16%, detritivore abundance by 119% and microbivore abundance by 89% through litter pathway. In the rhizosphere, invasive plants reduced bacterial biomass by 12%,...

Data from: Livestock grazing regulates ecosystem multifunctionality in semi‐arid grassland

Haiyan Ren, Valerie T. Eviner, Weiyang Gui, Gail W.T. Wilson, Adam B. Cobb, Gaowen Yang, Yingjun Zhang, Shuijin Hu, Yongfei Bai & Gail W. T. Wilson
1. Ecological theories and experimental evidence indicate that human activity induced losses in biodiversity can have substantial impacts on multiple ecosystem functions. It remains unclear, however, how grazing affects grassland biodiversity and ecosystem multifunctionallity (EMF). 2. Here, we assessed the grazing effects on different dimensions of biodiversity (i.e. plants and soil microbes) and EMF based on a 11-year field experiment in a semi-arid grassland. 3. We found that soil organic C, available nitrogen, and plant...

Replacing the 238th aspartic acid with an arginine impaired the oligomerization activity and inflammation-inducing property of pyolysin

Wenlong Zhang, Haili Wang, Bing Wang, Yue Zhang, Yunhao Hu, Bo Ma & Junwei Wang
Trueperella pyogenes (T. pyogenes) is an important opportunistic pathogen. Pyolysin (PLO) importantly contributes to the pathogenicity of T. pyogenes. However, the relationship between the structure and function and the virulence of PLO is not well documented. In the current study, recombinant PLO (rPLO) and three rPLO mutants were prepared. rPLO D238R, a mutant with the 238th aspartic acid replaced with an arginine, showed impairment in oligomerization activity on cholesterol-containing liposome and pore-forming activity on sheep...

Data from: Facilitation promotes invasions in plant-associated microbial communities

Mei Li, Zhong Wei, Jianing Wang, Alexandre Jousset, Ville-Petri Friman, Yangchun Xu, Qirong Shen & Thomas Pommier
While several studies have established a positive correlation between community diversity and invasion resistance, it is less clear how species interactions within resident communities shape this process. Here, we experimentally tested how antagonistic and facilitative pairwise interactions within resident model microbial communities predict invasion by the plant–pathogenic bacterium Ralstonia solanacearum. We found that facilitative resident community interactions promoted and antagonistic interactions suppressed invasions both in the lab and in the tomato plant rhizosphere. Crucially, pairwise...

Data from: Carbon resource richness shapes bacterial competitive interactions by alleviating growth-antibiosis trade-off

Chunlan Yang, Yue Dong, Ville-Petri Friman, Alexandre Jousset, Zhong Wei, Yangchun Xu & Qirong Shen
Antibiosis and resource competition are major drivers shaping the assembly, diversity and functioning of microbial communities. While it is recognised that competition is sensitive to environmental conditions, it is unclear to what extent this mediated by the availability of different carbon resources. Here we used a model laboratory system to directly test this by exploring how carbon resource richness and identity shape resource competition and antibiosis between plant probiotic Bacillus amyloliquefaciens and phytopathogenic Ralstonia solanacearum...
