    Cellulase and Macerozyme-PEG-mediated Transformation of Moss Protoplasts
    This protocol describes the generation of protoplasts from protonemal tissue of the moss Physcomitrium patens (syn. Physcomitrella patens), using Cellulase ONOZUKA R10 and Macerozyme R10, followed by polyethylene glycol (PEG) ...
    Efficient Transient Gene Knock-down in Tobacco Plants Using Carbon Nanocarriers
    Authors:  Gozde S. Demirer and Markita P. Landry, date: 01/05/2021, view: 1614, Q&A: 0
    Gene knock-down in plants is a useful approach to study genotype-phenotype relationships, render disease resistance to crops, and enable efficient biosynthesis of molecules in plants. Small interfering RNA (siRNA)-mediated gene silencing is one of ...
    Dual sgRNA-based Targeted Deletion of Large Genomic Regions and Isolation of Heritable Cas9-free Mutants in Arabidopsis
    Authors:  Yu Jin and Sebastian Marquardt, date: 10/20/2020, view: 2239, Q&A: 0
    CRISPR/Cas9 system directed by a gene-specific single guide RNA (sgRNA) is an effective tool for genome editing such as deletions of few bases in coding genes. However, targeted deletion of larger regions generate loss-of-function alleles ...
    Safe DNA-extraction Protocol Suitable for Studying Tree-fungus Interactions
    Authors:  Susanna Keriö, Eeva Terhonen and Jared M. LeBoldus, date: 06/05/2020, view: 3213, Q&A: 0
    We present a safe and low-cost method suitable for DNA extraction from mycelium and tree tissue samples. After sample preparation, the extraction takes about 60 min. Method performance was tested by extracting DNA from various tree tissue samples ...
    Barley Transformation by Particle Bombardment Using Callus
    Author:  Sung-Yong Kim, date: 06/05/2020, view: 1460, Q&A: 0
    The delivery of desired construct into plant cells relies mainly on Agrobacterium-mediated transformation. However, Agrobacterium transformation is still very challenging for barley as only one genotype is amendable to ...
    Construction of Antisense RNA-mediated Gene Knock-down Strains in the Cyanobacterium Anabaena sp. PCC 7120
    Authors:  Amit Srivastava, Anand Ballal, Karl Forchhammer and Anil Kumar Tripathi, date: 02/20/2020, view: 2492, Q&A: 0
    Anabaena sp. PCC 7120 (hereafter Anabaena) is a model cyanobacterium to study nitrogen fixation, cellular differentiation and several other key biological functions that are analogous in plants. As with any other organism, many ...
    Fluorescence Immunolocalization in Mitotic Chromosome Spreads from Maize Embryos
    Authors:  Jing-Han Liu, Ya-zhong Wang, Lin Chen and Yan He, date: 06/20/2019, view: 2223, Q&A: 0
    Immunolocalization is a necessary technique in the study of chromosome structure and function. It can provide important information for better understanding the relation between epigenetic modifications and chromosome condensation. In this protocol, ...
    In vitro Protein-DNA Binding Assay (AlphaScreen® Technology)
    Authors:  Mika Nomoto, Yasuomi Tada and Hironaka Tsukagoshi, date: 02/05/2019, view: 4948, Q&A: 0
    Identification of specific DNA binding sites of transcription factors is important in understanding their functions. Recent techniques allow us to investigate genome-wide in vivo binding positions by chromatin immunoprecipitation combined ...
    Tethered Chromosome Conformation Capture Sequencing in Triticeae: A Valuable Tool for Genome Assembly
    Authors:  Axel Himmelbach, Ines Walde, Martin Mascher and Nils Stein, date: 08/05/2018, view: 5687, Q&A: 0
    Chromosome conformation capture sequencing (Hi-C) is a powerful method to comprehensively interrogate the three-dimensional positioning of chromatin in the nucleus. The development of Hi-C can be traced back to successive increases in the resolution ...
    High Resolution Melting Temperature Analysis to Identify CRISPR/Cas9 Mutants from Arabidopsis
    Authors:  Cynthia Denbow, Sonia Carole Ehivet and Sakiko Okumoto, date: 07/20/2018, view: 5720, Q&A: 0
    CRISPR/Cas9 made targeted mutagenesis and genome editing possible for many plant species. One of the ways that the endonuclease is used for plant genetics is the creation of loss-of-function mutants, which typically result from erroneous DNA repair ...
