Bats are connected with the increasing numbers of emerging and re-emerging viruses that may break the species barrier and spread into the human population. Coronaviruses are one of the most common viruses discovered in bats, which were considered as the natural source of recent human-susceptible coronaviruses, i.e. SARS-COV and MERS-CoV. Our previous study reported the discovery of a bat-derived putative cross-family recombinant coronavirus with a reovirus gene p10, named as Ro-BatCoV GCCDC1. In this report, through a two-year follow-up of a special bat population in one specific cave of south China, we illustrate that Ro-BatCoV GCCDC1 persistently circulates among bats. Notably, through the longitudinal observation, we identified the dynamic evolution of Ro-BatCoV GCCDC1 in bats represented by continuously recombination events. Our study provides the first glimpse of the virus evolution in one longitudinally observed bat population cohort and underlines the surveillance and pre-warning of potential interspecies transmittable viruses in bats.

[目的]研究应用计算机辅助外科(computer aided surgery,CAS)施行传统性全膝关节置换器械的新技术。[方法]30例膝关节内翻畸形患者,由同一位医师施行传统性全膝关节置换术,术后全部患者行患肢直立位冠状面X线摄影,选其中20例作为研究对象,评估移植假体位置的正确性程度。[结果]20例患者行X线分析研究,以下列不同角度进行测定,结果分析使用SPSS版本19。冠状轴线:股骨部假体位置沿股骨机械轴线,均值为:2.5°内翻～4.4°外翻(SD 0.33);股骨部假体位置为:2.5°内翻～1.7°外翻(SD 0.23);总的股胫机械轴线角度为:3.2°内翻～4.5°外翻(SD 0.40)。假体组成部分超出±3°内翻/外翻者,胫骨0例,股骨1例。股骨与胫骨机械性轴线超过3°内翻/外翻为3例。以上数据表明膝关节外科能全面取得韧带的平衡。矢状轴线:研究假体置换的矢状轴线最佳位置,尚存在争议。故未作分析。[结论]CAS适用于传统性全膝关节置换术,既不增加患者痛苦,还能进一步完善外科手术技术,使假体移植达到正确位置。

Feeding Biochar to Cows:An Innovative Solution for Improving Soil Fertility and Farm Productivity

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 soft 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.

Multimodel projections and uncertainties of net ecosystem production in China over the twenty-first century

Ecosystems in China have been absorbing anthropogenic CO2 over the last three decades. Here, we assess future carbon uptake in China using models from phase 5 of Coupled Model Intercomparison Project under four socio-economic scenarios. The average of China's carbon sink from 2006 to 2100 represented by multimodel mean net ecosystem production(NEP) is projected to increase(relative to averaged NEP from 1976 to 2005) in the range of 0.137 and 0.891 Pg C a-1across differentscenarios. Increases in NEP are driven by increases in net primary production exceeding increases in heterotrophic respiration, and future carbon sink is mainly attributed to areas located in eastern China. However, there exists a considerable model spread in the magnitude of carbon sink and model spread tends to be larger when future climate change becomes more intense. The model spread may result from intermodel discrepancy in the magnitude of CO2 fertilization effect on photosynthesis, soil carbon turnover time, presence of carbon-nitrogen cycle and interpretation of land-use changes. For better quantifying future carbon cycle, a research priority toward improving model representation of these processes is recommended.

Plants sense neighbor proximity as a decrease in the red to far-red ratio of incoming light,which triggers a series of developmental responses known collectively as the "shade avoidance syndrome"(SAS).In Arabidopsis thalianu,phytochrome B is the major sensor of shade light,but to date phytochrome excitation has not been linked directly to a growth response. We show that the bHLH transcription factor,PIF7,previously shown to interact with phytochrome B,accumulates in its dephosphorylated form in shade,allowing it to bind to the promoters of a subset of auxin biosynthetic genes and increase their *** new auxin is required for changes in growth in the shade,our studies link directly the perception of a light quality signal to a rapid growth *** are also working on a most shade induced gene PIL1 and find PIL1 protein accumulates after shade treatment and PIL1 overexpression attenuates expression of many shade-induced ***,PIL1 protein represses PIL1 expression to form a self-limiting feedback ***,PIL1 is a negative regulator of the shade-induced transcriptional response in Arabidopsis.
