| 1 | Genome-wide transcriptome analysis of roots in two rice varieties in response to alternate wetting and drying irrigation显示文摘Alternate wetting and drying(AWD)irrigation has been widely used as an efficient rice production method to obtain better yield without continuous flooding(CF)of the paddy field.However,how this practice affects gene expression to regulate rice physiology and morphology is largely unknown.In this study,we used two rice varieties,Nipponbare,a lowland rice cultivar,and Gaoshan 1,an upland cultivar,and found that root dry weight(RDW)and root oxidation activity(ROA)in both cultivars substantially increased in response to AWD.We then analyzed the differences in transcriptome profiles of their roots irrigated in AWD vs.CF conditions.AWD responsive genes are mainly involved in lignin biosynthetic pathway and phytohormone signal transduction pathway and belong mainly to b HLH,b ZIP,NAC,WRKY,and HSF transcription factor families.We discussed how these differentially expressed genes may contribute to the morphological adaptations observed in roots exposed to AWD.This analysis also provides useful information to explain the similarities and differences in adaptation to AWD irrigation between the two rice ecotypes. | Tao Song Debatosh Das Feng Yang Moxian Chen Yuan Tian Chaolin Cheng Chao Sun Weifeng Xu Jianhua Zhang | 2020 | The Crop Journal2020，8，4： | 1 |
| 2 | Mechanical property and biological behaviour of additive manufactured TiNi functionally graded lattice structure显示文摘Bio-inspired porous metallic scaffolds have tremendous potential to be used as artificial bone substitutes.In this work,a radially graded lattice structure (RGLS),which mimics the structures of natural human bones,was designed and processed by laser powder bed fusion of martensitic Ti-rich TiNi powder.The asymmetric tension-compression behaviour,where the compressive strength is significantly higher than the tensile strength,is observed in this Ti-rich TiNi material,which echoes the mechanical behaviour of bones.The morphologies,mechanical properties,deformation behaviour,and biological compatibility of RGLS samples were characterised and compared with those in the uniform lattice structure.Both the uniform and RGLS samples achieve a relative density higher than 99%.The graded porosities and pore sizes in the RGLS range from 40%-80% and 330-805 µm,respectively,from the centre to the edge.The chemical etching has significantly removed the harmful partially-melted residual powder particles on the lattice struts.The compressive yield strength of RGLS is 71.5 MPa,much higher than that of the uniform sample (46.5 MPa),despite having a similar relative density of about 46%.The calculated Gibson-Ashby equation and the deformation behaviour simulation by finite element suggest that the dense outer regions with high load-bearing capability could sustain high applied stress,improving the overall strength of RGLS significantly.The cell proliferation study suggests better biological compatibility of the RGLS than the uniform structures.The findings highlight a novel strategy to improve the performance of additively manufactured artificial implants by bio-inspiration. | Chaolin Tan Cheng Deng Sheng Li Alessandro Abena Parastoo Jamshidi Khamis Essa Likang Wu Guohua Xu Moataz M Attallah Jia Liu | 2022 | International Journal of Extreme Manufacturing2022，4，4： | 0 |
