Combining Raman Imaging and Multivariate Analysis to Visualize Lignin, Cellulose, and Hemicellulose in the Plant Cell Wall

Xun Zhang¹, Sheng Chen¹, Feng Xu¹

¹Beijing Key Laboratory of Lignocellulosic Chemistry, Beijing Forestry University

This protocol aims to present a general method to visualize lignin, cellulose, and hemicellulose in plant cell walls using Raman imaging and multivariate analysis.

The ultrasonic cleaning method was applied to elute the particulate matter (PM) retained on leaf surfaces after PM was eluted by the conventional cleaning methods (water cleaning only or water cleaning plus brush cleaning). The methodology can help to improve the estimation accuracy for PM retention capacity of leaves.

In order to observe ultrastructure of insect sensilla, scanning and transmission electron microscopy (SEM and TEM, respectively) sample preparation protocol were presented in the study. Tween 20 was added into the fixative to avoid sample deformation in SEM. Fluorescence microscopy was helpful for improving slicing accuracy in TEM.

Biology

Development of an Individual-Tree Basal Area Increment Model using a Linear Mixed-Effects Approach

Wenwen Wang¹, Yanfeng Bai², Chunqian Jiang², Jinghui Meng¹

¹Research Center of Forest Management Engineering of National Forestry and Grassland Administration, Beijing Forestry University, ²Research Institute of Forestry, Chinese Academy of Forestry

Mixed-effects models are flexible and useful tools for analyzing data with a hierarchical stochastic structure in forestry and could also be used to significantly improve the performance of forest growth models. Here, a protocol is presented that synthesizes information relating to linear mixed-effects models.

CcCIPK14 Gene Function Analysis to Illuminate the Efficient Root Transgenic System

Tengyue Liu^*1, Zhihua Song^*1, Tingting Du¹, Wanlong Yang¹, Ting Chen¹, Ying Han¹, Biying Dong¹, Hongyan Cao¹, Lili Niu^1,2, Rohul Amin¹, Haojie jin¹, Qing Yang^1,2, Dong Meng^1,2, Yujie Fu^1,2

¹College of Forestry, Beijing Forestry University, ²Beijing Advanced Innovation Center for Tree Breeding by Molecular Design, Beijing Forestry University

Here we present an efficient and stable transformation system for the functional analysis of the CcCIPK14 gene as an example, providing a technical basis for studying the metabolism of non-model plants.

In Vitro Reconstitution of the Actin Cytoskeleton Inside Giant Unilamellar Vesicles

Sheng Chen¹, Zachary Gao Sun^2,3, Michael P. Murrell^1,2,3

¹Department of Biomedical Engineering, Yale University, ²Systems Biology Institute, Yale University, ³Department of Physics, Yale University

In this manuscript, we demonstrate the experimental techniques to encapsulate the F-actin cytoskeleton into giant unilamellar lipid vesicles (also called liposomes), and the method to form a cortex-biomimicking F-actin layer at the inner leaflet of the liposome membrane.
