1Developing More Effective Enhanced Biochar Fertilisers for Improvement of Pepper Yield and Quality显示文摘Utilization of biochar at high application rates can increase soil C and crop yields, decrease greenhouse gas emissions and reduce nutrient run-off from soils. However, the high application rate of 10 t ha-1may not return a profit to the farmer due to the high cost of biochar. In this study biochar was modified through pre-treating the biomass and post-treating with phosphoric acid, minerals and different chemical fertilisers to study the effects of two new enhanced biochar fertilisers on the yield and quality of green pepper in a field experiment with 5 fertilisation treatments and 3 replications. The two new biochar fertilisers significantly(P < 0.05) increased the yield of green pepper(11.33–11.47 t ha-1), compared with the conventional chemical fertiliser(9.72 t ha-1). The biochar fertiliser treatments improved the vitamin C content of green pepper from 236.99 to 278.28 mg kg-1, and also significantly(P < 0.05) reduced the nitrate content from 132.32 to 101.92 mg kg-1, compared with chemical fertiliser. This study indicated that, compared to the use of conventional chemical fertiliser, all of the biochar fertiliser treatments could significantly improve the yield and quality of green pepper.YAO Chunxue Stephen JOSEPH LI Lianqing PAN Genxing Yun LIN Paul MUNROE Ben PACE Sarasadat TAHERYMOOSAVI Lukas VAN ZWIETEN Torsten THOMAS Shaun NIELSEN Jun YE Scott DONNE 2015Pedosphere2015,25,5:8
2Effects of Enriched Biochars Containing Magnetic Iron Nanoparticles on Mycorrhizal Colonisation,Plant Growth,Nutrient Uptake and Soil Quality Improvement显示文摘At present, there is little commercial sale of biochar, since farmers find they can not gain a return on their investment in this amendment in the first few years after its application, because of the high cost associated with large application rates. To overcome this constraint, development of artificially aged enriched biochar-mineral complexes(BMCs), having a higher mineral content, surface functionality, exchangeable cations, high concentration of magnetic iron(Fe) nanoparticles, and higher water-extractable organic compounds has been undertaken by a combined team of researchers and a commercial company. Two biochars produced under different pyrolysis conditions were activated with a phosphoric acid treatment. A mixture of clay, chicken litter, and minerals were added to the biochar, and then this composite was torrefied at either 180 or 220?C. In this study a pot experiment was carried out in glasshouse conditions to determine the effects of four different BMCs, with different formulations applied at rates of 100 and 200 kg ha-1, on the mycorrhizal colonisation, wheat growth and nutrient uptake, and soil quality improvement. It was found that the phosphorus(P) and nitrogen uptake in wheat shoots were significantly greater for a low application rate of BMCs(100 kg ha-1). The present formulation of BMC was effective in enhancing growth of wheat at low application rate(100 kg ha-1). The increase in growth appeared due to an increase in P uptake in the plants that could be partly attributed to an increase in mycorrhizal colonisation and partly due to the properties of the BMC.Stephen JOSEPH Hossain M.ANAWAR Paul STORER Paul BLACKWELL Chee CHIA Yun LIN Paul MUNROE Scott DONNE Josip HORVAT Jianli WANG Zakaria M.SOLAIMAN 2015Pedosphere2015,25,5:7
3Demographic trade-offs determine species abundance and diversity显示文摘Aims Much recent theory has focused on the role of neutral processes in assembling communities,but the basic assumption that all species are demographically identical has found little empirical support.Here,we show that the framework of the current neutral theory can easily be generalized to incorporate species differences so long as fitness equivalence among individuals is maintained through trade-offs between birth and death.Methods Our theory development is based on a careful reformulation of the Moran model of metacommunity dynamics in terms of a non-linear one-step stochastic process,which is described by a master equation.Important Findings We demonstrate how fitness equalization through demographic trade-offs can generate significant macroecological diversity patterns,leading to a very different interpretation of the relation between Fisher’s a and Hubbell’s fundamental biodiversity number.Our model shows that equal fitness(not equal demographics)significantly promotes species diversity through strong selective sieving of community membership against high-mortality species,resulting in a positive association between species abundance and per capita death rate.An important implication of demographic trade-off is that it can partly explain the excessively high speciation rates predicted by the neutral theory of the stronger symmetry.Fitness equalization through demographic trade-offs generalizes neutral theory by considering heterospecific demographic difference,thus representing a significant step toward integrating the neutral and niche paradigms of biodiversity.Da-Yong Zhang Bo-Yu Zhang Kui Lin Xinhua Jiang Yi Tao Stephen Hubbell Fangliang He Annette Ostling 2012Journal of Plant Ecology2012,5,1:4
4Feeding Biochar to Cows:An Innovative Solution for Improving Soil Fertility and Farm Productivity显示文摘Addition of biochar produced through thermal decomposition of biomass has been seen as a strategy to improve soils and to sequester carbon(C), but wide scale implementation of the technology requires to devise innovative profitable solutions. To develop biochar utilisation with an integrated system approach, an innovative program was implemented in 2012 on a 53-ha farm in Western Australia to determine the costs and benefits of integrating biochar with animal husbandry and improvement of pastures. Biochar was mixed with molasses and fed directly to cows. The dung-biochar mixture was incorporated into the soil profile by dung beetles.We studied the changes in soil properties over 3 years. Biochar extracted from fresh dung and from the soil to a depth of 40 cm was characterised. A preliminary financial analysis of the costs and benefits of this integrated approach was also undertaken. The preliminary investigation results suggested that this strategy was effective in improving soil properties and increasing returns to the farmer. It was also concluded that the biochar adsorbed nutrients from the cow's gut and from the dung. Dung beetles could transport this nutrient-rich biochar into the soil profile. There was little evidence that the recalcitrant component of the biochar was reduced through reactions inside the gut or on/in the soil. Further research is required to quantify the long-term impact of integrating biochar and dung beetles into the rearing of cows.Stephen JOSEPH Doug POW Kathy DAWSON David R.G.MITCHELL Aditya RAWAL James HOOK Sarasadat TAHERYMOOSAVI Lukas VAN ZWIETEN Joshua RUST Scott DONNE Paul MUNROE Ben PACE Ellen GRABER Torsten THOMAS Shaun NIELSEN Jun YE Yun LIN PAN Genxing LI Lianqing Zakaria M.SOLAIMAN 2015Pedosphere2015,25,5:2

6Tet2 Regulates Osteoclast Differentiation by Interacting with Runx1 and Maintaining Genomic 5-Hydroxymethylcytosine(5hmC)显示文摘As a dioxygenase, Ten-Eleven Translocation 2(TET2) catalyzes subsequent steps of 5-methylcytosine(5 mC) oxidation. TET2 plays a critical role in the self-renewal, proliferation,and differentiation of hematopoietic stem cells, but its impact on mature hematopoietic cells is not well-characterized. Here we show that Tet2 plays an essential role in osteoclastogenesis. Deletion of Tet2 impairs the differentiation of osteoclast precursor cells(macrophages) and their maturation into bone-resorbing osteoclasts in vitro. Furthermore, Tet2^(-/-) mice exhibit mild osteopetrosis, accompanied by decreased number of osteoclasts in vivo. Tet2 loss in macrophages results in the altered expression of a set of genes implicated in osteoclast differentiation, such as Cebpa, Mafb, and Nfkbiz. Tet2 deletion also leads to a genome-wide alteration in the level of 5-hydroxymethylcytosine(5 hmC) and altered expression of a specific subset of macrophage genes associated with osteoclast differentiation. Furthermore, Tet2 interacts with Runx1 and negatively modulates its transcriptional activity. Our studies demonstrate a novel molecular mechanism controlling osteoclast differentiation and function by Tet2, that is, through interactions with Runx1 and the maintenance of genomic 5 hmC. Targeting Tet2 and its pathway could be a potential therapeutic strategy for the prevention and treatment of abnormal bone mass caused by the deregulation of osteoclast activities.Yajing Chu Zhigang Zhao David Wayne Sant Ganqian Zhu Sarah M.

7Total Ginsenoside Extract from Panax ginseng Enhances Neural Stem Cell Proliferation and Neuronal Differentiation by Inactivating GSK-3β显示文摘Objective:To study the effects of total ginsenosides(TG)extract from Panax ginseng on neural stem cell(NSC)proliferation and differentiation and their underlying mechanisms.Methods:The migration of NSCs after treatment with various concentrations of TG extract(50,100,or 200μg/mL)were monitored.The proliferation of NSCs was examined by a combination of cell counting kit-8 and neurosphere assays.NSC differentiation mediated by TG extract was evaluated by Western blotting and immunofluorescence staining to monitor the expression of nestin and microtubule associated protein 2(MAP2).The GSK-3β/β-catenin pathway in TG-treated NSCs was examined by Western blot assay.The NSCs with constitutively active GSK-3βmutant were made by adenovirus-mediated gene transfection,then the proliferation and differentiation of NSCs mediated by TG were further verified.Results:TG treatment significantly enhanced NSC migration(P<0.01 or P<0.05)and increased the proliferation of NSCs(P<0.01 or P<0.05).TG mediation also significantly upregulated MAP2 expression but downregulated nestin expression(P<0.01 or P<0.05).TG extract also significantly induced GSK-3βphosphorylation at Ser9,leading to GSK-3βinactivation and,consequently,the activation of the GSK-3β/β-catenin pathway(P<0.01 or P<0.05).In addition,constitutive activation of GSK-3βin NSCs by the transfection of GSK-3βS9 A mutant was found to significantly suppress TG-mediated NSC proliferation and differentiation(P<0.01 or P<0.05).Conclusion:TG promoted NSC proliferation and neuronal differentiation by inactivating GSK-3β.LIN Kai-li ZHANG Ji CHUNG Hau-lam WU Xin-yi LIU Bin ZHAO Bo-xin SZE Stephen Cho-wing ZHOU Ping-zheng YUNG Ken Kin-lam ZHANG Shi-qing 2022Chinese Journal of Integrative Medicine2022,28,3:2
