    Using Arabidopsis Mesophyll Protoplasts to Study Unfolded Protein Response Signaling
    Authors:  Yan Bao and Diane C. Bassham, date: 12/05/2018, view: 2066, Q&A: 0
    [Abstract] Various environmental stresses or artificial reagents can trigger unfolded protein accumulation in the endoplasmic reticulum (ER) due to the folding capacity of the ER being exceeded. This is termed ER stress, and triggers the unfolded protein response (UPR). Assays for activation of the UPR in plants include Tunicamycin (Tm)- or dithiothreitol ...
    Isolation of Guard-cell Enriched Tissue for RNA Extraction
    Authors:  Pirko Jalakas, Dmitry Yarmolinsky , Hannes Kollist and Mikael Brosche, date: 08/05/2017, view: 9716, Q&A: 0
    [Abstract] This is a protocol for isolation of guard cell enriched samples from Arabidopsis thaliana plants for RNA extraction. Leaves are blended in ice-water and filtered through nylon mesh to obtain guard cell enriched fragments. With guard cell enriched samples, gene expression analysis can be done, e.g., comparing different gene ...
    Isolation of Fucus serratus Gametes and Cultivation of the Zygotes
    Authors:  Amandine Siméon and Cécile Hervé, date: 07/20/2017, view: 4143, Q&A: 0
    [Abstract] Zygotes of the Fucale species are a powerful model system to study cell polarization and asymmetrical cell division (Bisgrove and Kropf, 2008). The Fucale species of brown algae grow in the intertidal zone where they reproduce by releasing large female eggs and mobile sperm in the surrounding seawater. The gamete release can be induced from ...
    Plasma Membrane Preparation from Lilium davidii and Oryza sativa Mature and Germinated Pollen
    Authors:  Ning Yang, Bing Han, Lingtong Liu, Hao Yang and Tai Wang, date: 05/20/2017, view: 4370, Q&A: 0
    [Abstract] Pollen germination is an excellent process to study cell polarity establishment. During this process, the tip-growing pollen tube will start elongating. The plasma membrane as the selectively permeable barrier that separates the inner and outer cell environment plays crucial roles in this process. This protocol described an efficient aqueous ...
    A Ribosome Footprinting Protocol for Plants
    Authors:  Catharina Merchante, Qiwen Hu, Steffen Heber, Jose Alonso and Anna N. Stepanova, date: 11/05/2016, view: 8132, Q&A: 0
    [Abstract] Ribosome footprinting, or Ribo-seq, has revolutionized the studies of translation. It was originally developed for yeast and mammalian cells in culture (Ingolia et al., 2009). Herein, we describe a plant-optimized hands-on ribosome footprinting protocol derived from previously published procedures of polysome isolation (Ingolia et al ...
    An Efficient Procedure for Protoplast Isolation from Mesophyll Cells and Nuclear Fractionation in Rice
    [Abstract] Plant protoplasts, a proven physiological and versatile cell system, are widely used in high-throughput analysis and functional characterization of genes. Green protoplasts have been successfully used in investigations of plant signal transduction pathways related to hormones, metabolites and environmental challenges. This protocol, adapted from ...
    Protein Degradation Assays in Arabidopsis Protoplasts
    [Abstract] Plant transformation and exogenous protein expression is essential for molecular biology and biotechnology. Current approaches of stable plant transformation might be problematic and very time-consuming. Because of this, transient expression in protoplasts has become valuable alternative, being less cost and time-effective at the same time. ...
    Protoplast Preparation and Determination of Cell Death
    Author:  Antoine Danon, date: 06/20/2014, view: 11813, Q&A: 3
    [Abstract] The protoplasts assay constitutes a powerful tool that allows an easy uptake of active agents and a precise quantification of cell death induction in different populations. Our study showed that the basal level of cell death in our controls is low and stable throughout the length of our experiments (Danon et al., 2005; Pineau et al. ...
    Isolation of Rice Embryo Single Cell Type using Laser Capture Microdissection (LCM)
    Author:  Tie Liu, date: 09/20/2012, view: 8909, Q&A: 0
    [Abstract] A lot of transcriptional profiling in plant and animals has used RNAs samples from many different cell types. The laser-capture microdissection (LCM) can identify and harvest pure cellular populations directly from heterogenous tissues based on histological identification. The molecules or protein isolated from LCM-captured cells can be suitable ...
