Biology Isolation and Transcriptome Analysis of Plant Cell Types Jun Zhang1, Mayra Ahmad1, Rongrong Xie1, Hongbo Gao1 1Joint Center for Single Cell Biology, School of Agriculture and Biology, Shanghai Jiao Tong University The feasibility and effectiveness of high-throughput scRNA-seq methods herald a single-cell era in plant research. Presented here is a robust and complete procedure for isolating specific Arabidopsis thaliana root cell types and subsequent transcriptome library construction and analysis. Bioengineering Viscoelastic Characterization of Soft Tissue-Mimicking Gelatin Phantoms using Indentation and Magnetic Resonance Elastography Yuan Feng1, Suhao Qiu1, Yu Chen1, Runke Wang1, Zhao He1, Linghan Kong1, Yi Chen1, Shengyuan Ma1 1School of Biomedical Engineering, Shanghai Jiao Tong University This article presents a demonstration and summary of protocols of making gelatin phantoms that mimic soft tissues, and the corresponding viscoelastic characterization using indentation and magnetic resonance elastography. Biology Structure-Based Simulation and Sampling of Transcription Factor Protein Movements along DNA from Atomic-Scale Stepping to Coarse-Grained Diffusion Chao E*1, Liqiang Dai*1,2, Jiaqi Tian3,4, Lin-Tai Da4, Jin Yu5,6,7 1Beijing Computational Science Research Center, 2Shenzhen JL Computational Science and Applied Research Institute, 3School of Medical Informatics and Engineering, Xuzhou Medical University, 4Key Laboratory of Systems Biomedicine (Ministry of Education), Shanghai Center for Systems Biomedicine, Shanghai Jiao Tong University, 5Department of Physics and Astronomy, University of California, Irvine, 6Department of Chemistry, University of California, Irvine, 7NSF-Simons Center for Multiscale Cell Fate Research, University of California, Irvine The goal of this protocol is to reveal structural dynamics of one-dimensional diffusion of protein along DNA, using a plant transcription factor WRKY domain protein as an exemplary system. To do this, both atomistic and coarse-grained molecular dynamics simulations along with extensive computational samplings have been implemented.
