    Using 14C-acetate Pulse-chase Labeling to Study Fatty Acid and Glycerolipid Metabolism in Plant Leaves
    Authors:  Linhui Yu, Chao Zhou, Jilian Fan and Changcheng Xu, date: 02/05/2021, view: 278, Q&A: 0
    [Abstract]

    Lipids metabolism is comprised of networks of reactions occurred in different subcellular compartments. Isotopic labeling is a good way to track the transformations and movements of metabolites without perturbing overall cellular metabolism. Fatty acids, the building blocks of membrane lipids and storage triacylglycerols, are synthesized in

    Non-radioactive Assay to Determine Product Profile of Short-chain Isoprenyl Diphosphate Synthases
    Authors:  Avanish Rai and Dinesh A. Nagegowda, date: 01/05/2021, view: 492, Q&A: 0
    [Abstract] Isoprenoids represent the largest class of metabolites with amazing diversities in structure and function. They are involved in protecting plants against pathogens or herbivores or involved in attracting pollinators. Isoprenoids are derived from geranyl diphosphate (GPP; C10), farnesyl diphosphate (FPP; C15), geranylgeranyl ...
    Analysis of Isotopically-labeled Monogalactosyldiacylglycerol Molecular Species from [14C]Acetate-Labeled Tobacco Leaves
    Authors:  Hari Kiran Kotapati and Philip D. Bates, date: 12/20/2020, view: 534, Q&A: 0
    [Abstract]

    Plant lipid metabolism is a dynamic network where synthesis of essential membrane lipids overlaps with synthesis of valuable storage lipids (e.g., vegetable oils). Monogalactosyldiacylglycerol (MGDG) is a key component of the chloroplast membrane system required for photosynthesis and is produced by multiple pathways within the lipid metabolic

    Pipecolic Acid Quantification Using Gas Chromatography-coupled Mass Spectrometry
    Authors:  Keshun Yu, Huazhen Liu and Pradeep Kachroo, date: 12/05/2020, view: 746, Q&A: 0
    [Abstract]

    Pipecolic acid (Pip), a non-proteinacious product of lysine catabolism, is an important regulator of immunity in plants and humans alike. For instance, Pip accumulation is associated with the genetic disorder Zellweger syndrome, chronic liver diseases, and pyridoxine-dependent epilepsy in humans. In plants, Pip accumulates upon pathogen infection

    Low-cost and High-throughput RNA-seq Library Preparation for Illumina Sequencing from Plant Tissue
    Authors:  Marta Bjornson, Kaisa Kajala, Cyril Zipfel and Pingtao Ding, date: 10/20/2020, view: 1218, Q&A: 0
    [Abstract] Transcriptome analysis can provide clues to biological processes affected in different genetic backgrounds or/and under various conditions. The price of RNA sequencing (RNA-seq) has decreased enough so that medium- to large-scale transcriptome analyses in a range of conditions are feasible. However, the price and variety of options for library ...
    A Protocol for Flavonols, Kaempferol and Quercetin, Staining in Plant Root Tips
    Author:  Nguyen Hoai Nguyen, date: 10/05/2020, view: 919, Q&A: 0
    [Abstract] Flavonols are a subclass of flavonoids of the group of plant secondary metabolites. In planta, flavonols play various functions such as antioxidant and natural regulator of auxin polar transport. Many lines of evidence have shown that flavonols also contribute to human health in anti-oxidation, anti-inflammation, and even prevention some ...
    The ATPase Activity of Escherichia coli Expressed AAA+-ATPase Protein
    Authors:  Amita Kaundal, Vemanna S. Ramu and Kirankumar S. Mysore, date: 08/05/2020, view: 1248, Q&A: 0
    [Abstract] ATPases are the enzymes that breakdown ATP to ADP and release inorganic phosphate (Pi). Here we provide a detailed protocol to determine the ATPase activity of a recombinant AAA+-ATPase protein (GENERAL CONTROL NON-REPRESSIBLE-4 [GCN4]) by spectrophotometric absorption at 360 nm to measure the accumulated inorganic phosphate. In ...
    Determination of Ureides Content in Plant Tissues
    Author:  Ignacio Lescano, date: 06/05/2020, view: 1357, Q&A: 0
    [Abstract] The ureides allantoin and allantoate are the main organic nitrogen compounds transported in several legumes, predominantly from N2 fixation. Moreover, recent studies point out a remarkable role for allantoin during several stress responses of plants other than legumes. The goal of this protocol is to determine ureides concentration in ...
    Purification of Protein-complexes from the Cyanobacterium Synechocystis sp. PCC 6803 Using FLAG-affinity Chromatography
    Authors:  Minna M. Koskela, Petra Skotnicová, Éva Kiss and Roman Sobotka, date: 05/20/2020, view: 1684, Q&A: 0
    [Abstract] Exploring the structure and function of protein complexes requires their isolation in the native state–a task that is made challenging when studying labile and/or low abundant complexes. The difficulties in preparing membrane-protein complexes are especially notorious. The cyanobacterium Synechocystis sp. PCC 6803 is a widely used model ...
    MAMP-triggered Medium Alkalinization of Plant Cell Cultures
    [Abstract] Plants recognize a wide variety of microbial molecules to detect and respond to potential invaders. Recognition of Microbe-Associated Molecular Patterns (MAMPs) by cell surface receptors initiate a cascade of biochemical responses that include, among others, ion fluxes across the plasma membrane. A consequence of such event is a decrease in the ...
