2A deep seismic sounding profile across the Tianshan Mountains显示文摘The deep seismic sounding profile across the Tianshan Mountains revealed a two-layer crustal structure in the Tianshan region, namely the lower and upper crusts. Lateral variations of layer velocity and thickness are evidently shown. Low-velocity layers spread discontinuously at the bottom of the upper crust. The Mono depth is 47 km in the Kuytun area and 50 km in the Xayar area. In the Tianshan Mountains, the Moho becomes deeper with the maximum depth of 62 km around the boundary between the southern and northern Tianshan Mountains. The average velocity ranges from 6.1 to 6.3 km/s in the crust and 8.15 km/s at the top of the upper mantle. Two groups of reliable reflective seismic phases of the Moho (Pm1 and Pm2) are recognized on the shot record section of the Kuytun area. A staked and offset region, 20-30 km long, is displayed within a shot-geophone distance of 190-210 km in Pm1 and Pm2. Calculation shows that the Moho is offset by 10 km in the northern Tianshan region, 62 km deep in the south whileLU Deyuan LI Qiusheng GAO Rui LI Yingkang LI Dexing LIU Wen ZHANG Zhiying 2000Chinese Science Bulletin2000,45,22:9
3The vernalization-induced long non-coding RNA VAS functions with the transcription factor TaRF2b to promote TaVRN1 expression for flowering in hexaploid wheat显示文摘Vernalization is a physiological process in which prolonged cold exposure establishes flowering competence in winter plants. In hexaploid wheat, TaVRN1 is a cold-induced key regulator that accelerates floral transition. However, the molecular mechanism underlying the gradual activation of TaVRN1 during the vernalization process remains unknown. In this study, we identified the novel transcript VAS (TaVRN1 alternative splicing) as a non-coding RNA derived from the sense strand of the TaVRN1 gene only in winter wheat, which regulates TaVRN1 transcription for flowering. VAS was induced during the early period of vernalization, and its overexpression promoted TaVRN1 expression to accelerate flowering in winter wheat. VAS physically associates with TaRF2b and facilitates docking of the TaRF2b-TaRF2a complex at the TaVRN1 promoter during the middle period of vernalization. TaRF2b recognizes the Sp1 motif within the TaVRN1 proximal promoter region, which is gradually exposed along with the disruption of a loop structure at the TaVRN1 locus during vernalization, to activate the transcription of TaVRN1. The tarf2b mutants exhibited delayed flowering, whereas transgenic wheat lines overexpressing TaRF2b showed earlier flowering. Taken together, our data reveal a distinct regulatory mechanism by which a long non-coding RNA facilitates the transcription factor targeting to regulate wheat flowering, providing novel insights into the vernalization process and a potential target for wheat genetic improvement.Shujuan Xu Qi Dong Min Deng Dexing Lin Jun Xiao Peilei Cheng Lijing Xing Yuda Niu Caixia Gao Wenhao Zhang Yunyuan Xu Kang Chong 2021Molecular Plant2021,14,9:7
4Genome editing in plants with MAD7 nuclease显示文摘MAD7 is an engineered nuclease of the Class 2 type V-A CRISPR-Cas(Cas12 a/Cpf1)family with a low level of homology to canonical Cas12 a nucleases.It has been publicly released as a royalty-free nuclease for both academic and commercial use.Here,we demonstrate that the CRISPR-MAD7 system can be used for genome editing and recognizes T-rich PAM sequences(YTTN)in plants.Its editing efficiency in rice and wheat is comparable to that of the widely used CRISPR-Lb Cas12 a system.We develop two variants,MAD7-RR and MAD7-RVR that increase the target range of MAD7,as well as an M-AFID(a MAD7-APOBEC fusion-induced deletion)system that creates predictable deletions from 50-deaminated Cs to the MAD7-cleavage site.Moreover,we show that MAD7 can be used for multiplex gene editing and that it is effective in generating indels when combined with other CRISPR RNA orthologs.Using the CRISPR-MAD7 system,we have obtained regenerated mutant rice and wheat plants with up to 65.6%efficiency.Qiupeng Lin Zixu Zhu Guanwen Liu Chao Sun Dexing Lin Chenxiao Xue Shengnan Li Dandan Zhang Caixia Gao Yanpeng Wang Jin-Long Qiu 2021Journal of Genetics and Genomics2021,48,6:4
5New experimental method for inundation effect of film condensation on horizontal tube bundle显示文摘Theory of film condensation heat transfer(FCHT) for vapor condensed on horizontal tube bundle(HTB) is vital to many industry processes.Meanwhile,the inundation effect is the key to model the film condensation heat transfer coefficient(CHTC) on HTB.This paper proposed a new experimental method,homologous method,to obtain the inundation effect precisely.Based on the requirements of the new test method,a new test facility was designed and established.Then,the superiority of homologous method for inundation effect was investigated based on experiment result and theoretic analysis.The results showed that the homogenous method can effectively control the experimental error of inundation effect,which is less than 50% of the error of CHTC,and less than 30% of the error of the inundation effect gained by routine method.The new test facility built for the homogenous method is excellent in obtaining the accurate inundation effect of film condensation on HTB.All the result is a foundation of the theoretical development of the FCHT on HTB.MA ZhiXian ZHANG JiLi SUN DeXing 2012Science China(Technological Sciences)2012,55,10:3

16Mechanical design and energy absorption of 3D novel hybrid lattice metamaterials显示文摘In this paper,three-dimensional(3D)novel hybrid lattice structures with exceptional mechanical properties and energy absorbing performances were proposed,and experimental and finite element simulation comparisons were performed to demonstrate their potential in mechanical application.First,different types of basic cubic unit cells were designed for constructing three types of novel hybrid metamaterials,in which stepped circulation of different unit cells was conceived to generate architected metamaterials.Afterwards,quasi-static compression experiments and finite element simulations were performed to study the deformation process and failure mechanisms of as-fabricated hybrid metamaterials.The energy absorption efficiency,specific energy absorption(SEA)indicators,and energy absorption capabilities of different hybrid lattice metamaterials were compared and analyzed.The results show that the deformation mechanisms of novel hybrid lattice were beneficial for generating remarkable elevated densification strain,and the energy absorption efficiency can be tailored by altering the types or sizes of basic unit cells.Strain-hardening and bilinear features were also obtained.ZHANG Peng Biligetu QI DeXing XUE Rui LIU Kai HUANG ZhiXin WU WenWang LI Ying 2021Science China(Technological Sciences)2021,64,10:1

20Genetic analysis and ecological niche modeling delimit species boundary of the Przewalski’s scorpion(Scorpiones: Buthidae) in arid Asian inland显示文摘Reliable delimitation of venomous scorpions is not only consequential to toxicological studies but also instructive to conservation and exploration of these important medical resources.In the present study,we delimited species boundary for the the Przewalski’s scorpion from arid northwest China through a combined approach employing phylogenetic analysis,ecological niche modeling and morphological comparison.Our results indicate that the Przewalski’s scorpion represent an independent taxonomic unit and should be recognized as full species rank,Mesobuthus przewalskii stat.nov.This species and the Chinese scorpion M.martensii represent the eastern members of the M.caucasicus species group which manifests a trans-Central Asia distribution across the Tianshan Mountains range.We also discussed the likely geographic barrier and climatic boundary that demarcate distributional range of the the Przewalski’s scorpion.Xueshu Zhang Gaoming Liu Yu Feng Dexing Zhang Chengmin Shi 2020Zoological Systematics2020,45,2:1
