    X-ray Crystallography: Seeding Technique with Cytochrome P450 Reductase
    Authors:  Bixia Zhang, Jacob A. Lewis, Rishi Hazra and ChulHee Kang, date: 11/05/2022, view: 452, Q&A: 0
    [Abstract]

    Cytochrome P450 reductase (CPR) is a multi-domain protein that acts as a redox partner of cytochrome P450s. The CPR contains a flavin adenine dinucleotide (FAD)–binding domain, a flavin mononucleotide (FMN)-binding domain, and a connecting domain. To achieve catalytic events, the FMN-binding domain needs to move relative to the FAD-binding

    Measurement of Ascorbate Peroxidase Activity in Sorghum
    Author:  Praveen Kumar, date: 10/20/2022, view: 736, Q&A: 0
    [Abstract]

    The ascorbate peroxidase (APX) is a widely distributed antioxidant enzyme. It differs from catalase and other peroxidases in that it scavenges/reduces reactive oxygen species (ROS) such as hydrogen peroxide (H2O2) to water using reduced ascorbate as the electron donor. It is advantageous over other similar antioxidant enzymes in scavenging ROS

    Collection of Xylem Exudates from the Model Plant Arabidopsis and the Crop Plant Soybean
    Authors:  Satoru Okamoto and Azusa Kawasaki, date: 10/05/2022, view: 1022, Q&A: 0
    [Abstract]

    A number of molecules, such as secreted peptides, have been shown to mediate root-to-shoot signaling in response to various conditions. The xylem is a pathway for water and molecules that are translocated from roots to shoots. Therefore, collecting and analyzing xylem exudates is an efficient approach to study root-to-shoot long-distance

    Extraction and Quantification of Plant Hormones and RNA from Pea Axillary Buds
    Authors:  Da Cao, Francois Barbier, Kaori Yoneyama and Christine A. Beveridge, date: 10/05/2022, view: 750, Q&A: 0
    [Abstract] The quantification of plant hormones and related gene expression is essential to improve the understanding of the molecular regulation of plant growth and development. However, plant hormone quantification is still challenging due to extremely low endogenous levels and high chemical diversity. In this study, we present a convenient extraction ...
    14C-paraquat Efflux Assay in Arabidopsis Mesophyll Protoplasts
    Authors:  Jin-Qiu Xia, Qian-Qian Liu and Cheng-Bin Xiang, date: 09/20/2022, view: 589, Q&A: 0
    [Abstract]

    Weeds compete with crops for growth resources, causing tremendous yield losses. Paraquat is one of the three most common non-selective herbicides. To study the mechanisms of paraquat resistance, we need to trace the movement of paraquat in plants and within the cell. 14C is a radioactive carbon isotope widely used to trace substances of

    Colocalization Assay with Fluorescent-tagged ATG8 Using a Nicotiana benthamiana-based Transient System
    Authors:  Jinyan Mai, Dandan Shang, Faqiang Li and Na Luo, date: 08/20/2022, view: 1046, Q&A: 0
    [Abstract]

    Autophagy is an evolutionarily conserved intracellular degradation process. During autophagy, a set of autophagy-related (ATG) proteins orchestrate the formation of double-bound membrane vesicles called autophagosomes to engulf cytoplasmic material and deliver it to the vacuole for breakdown. Among ATG proteins, the ATG8 is the only one decorating

    Quantitative Live Confocal Imaging in Aquilegia Floral Meristems
    Authors:  Ya Min, Stephanie J. Conway and Elena M. Kramer, date: 06/20/2022, view: 1653, Q&A: 0
    [Abstract]

    In this study, we present a detailed protocol for live imaging and quantitative analysis of floral meristem development in Aquilegia coerulea, a member of the buttercup family (Ranunculaceae). Using confocal microscopy and the image analysis software MorphoGraphX, we were able to examine the cellular growth dynamics during floral organ primordia

    Quantitative Analysis of Redox Pool (NAD+, NADH Content) in Plant Samples Under Aluminum Stress
    Authors:  Jay Prakash Awasthi, Bedabrata Saha, Hiroyuki Koyama and Sanjib Kumar Panda, date: 06/20/2022, view: 1619, Q&A: 0
    [Abstract]

    Nicotinamide adenine dinucleotide (NAD) is an essential cofactor of numerous enzymatic reactions found in all living cells. Pyridine nucleotides (NAD+ and NADH) are also key players in signaling through reactive oxygen species (ROS), being crucial in the regulation of both ROS-producing and ROS-consuming systems in plants. NAD content is a

    Investigation of Transposon DNA Methylation and Copy Number Variation in Plants Using Southern Hybridisation
    Authors:  Vivek Hari Sundar G. and P. V. Shivaprasad, date: 06/05/2022, view: 1090, Q&A: 0
    [Abstract]

    Plant genomes are pronouncedly enriched in repeat elements such as transposons. These repeats are epigenetically regulated by DNA methylation. Whole genome high-depth sequencing after bisulfite treatment remains an expensive and laborious method to reliably profile the DNA methylome, especially when considering large genomes such as in crops.

    In vitro Assays to Evaluate Specificity and Affinity in Protein-phospholipid Interactions
    [Abstract]

    Protein–lipid interactions play important roles in many biological processes, including metabolism, signaling, and transport; however, computational and structural analyses often fail to predict such interactions, and determining which lipids participate in these interactions remains challenging. In vitro assays to assess the physical
