    Measurement of Chloroplastic NAD Kinase Activity and Whole Tissue NAD Kinase Assay
    Authors:  Yuuma Ishikawa, Maki Kawai-Yamada and Shin-nosuke Hashida, date: 01/05/2020, view: 200, Q&A: 0
    [Abstract] Nicotinamide adenine dinucleotide phosphate (NADP) synthesis requires nicotinamide adenine dinucleotide (NAD) kinase activity, substrate NAD and ATP. The NAD kinase responds to various environmental stimuli and its activity is regulated via various regulatory pathways, such as Ca2+-dependent and redox-dependent signals. Conventional in ...
    Analysis of Monosaccharides from Arabidopsis Seed Mucilage and Whole Seeds Using HPAEC-PAD
    Authors:  Gillian H. Dean, Kresimir Sola, Faride Unda, Shawn D. Mansfield and George W. Haughn, date: 12/20/2019, view: 375, Q&A: 0
    [Abstract] Arabidopsis seed coat epidermal cells deposit a significant quantity of mucilage, composed of the cell wall components pectin, hemicellulose, and cellulose, into the apoplast during development. When mature seeds are hydrated, mucilage extrudes to form a gelatinous capsule around the seed. Determining the monosaccharide composition of ...
    Cell Wall Compositional Analysis of Rice Culms
    Authors:  Lanjun Zhang, Baocai Zhang and Yihua Zhou, date: 10/20/2019, view: 531, Q&A: 0
    [Abstract] The plant cell wall is a complicated network that is mainly constituted of polysaccharides, such as cellulose, hemicellulose and pectin. Many noncellulosic polysaccharides are further acetylated, which confers these polymers flexible physicochemical properties. Due to the significance of cell wall in plant growth and development, the analytic ...
    Visualization of Nitric Oxide, Measurement of Nitrosothiols Content, Activity of NOS and NR in Wheat Seedlings
    [Abstract] Nitric oxide (NO), is a redox-active, endogenous signalling molecule involved in the regulation of numerous processes. It plays a crucial role in adaptation and tolerance to various abiotic and biotic stresses. In higher plants, NO is produced either by enzymatic or non-enzymatic reduction of nitrite and an oxidative pathway requiring a putative ...
    Tensile Testing Assay for the Measurement of Tissue Stiffness in Arabidopsis Inflorescence Stem
    Authors:  Kouki Yoshida, Shingo Sakamoto and Nobutaka Mitsuda, date: 08/05/2019, view: 1341, Q&A: 1
    [Abstract] Lignocellulosic biomass is a versatile renewable resource for fuels, buildings, crafts, and biomaterials. Strategies of molecularly designing lignocellulose for industrial application has been developed by the discoveries of novel genes after the screenings of various mutants and transformed lines of Arabidopsis whose cell walls could be ...
    Quantification of Blumenol Derivatives as Leaf Biomarkers for Plant-AMF Association
    Authors:  Elisabeth Mindt, Ming Wang, Martin Schäfer, Rayko Halitschke and Ian T. Baldwin, date: 07/20/2019, view: 1232, Q&A: 0
    [Abstract] Symbiotic interactions between arbuscular mycorrhizal fungi (AMF) and plants are widespread among land plants and can be beneficial for both partners. The plant is provided with mineral nutrients such as nitrogen and phosphorous, whereas it provides carbon resources for the fungus in return. Due to the large economic and environmental impact, ...
    An Adjustable Protocol to Analyze Chemical Profiles of Non-sterile Rhizosphere Soil
    Authors:  Alex Williams, Jurriaan Ton and Pierre Pétriacq, date: 05/20/2019, view: 1823, Q&A: 0
    [Abstract] The analysis of chemical diversity in non-sterile rhizosphere soil has been a pressing methodological challenge for years. Rhizosphere-enriched chemicals (i.e., rhizochemicals) include root exudation chemicals, (microbial) breakdown products thereof, and de novo produced metabolites by rhizosphere-inhabiting microbes, all of ...
    Tracking Root Interactions System (TRIS) Experiment and Quality Control
    Authors:  Hassan Massalha, Elisa Korenblum, Orr H. Shapiro and Asaph Aharoni, date: 04/20/2019, view: 2032, Q&A: 0
    [Abstract] Soil organisms are diverse taxonomically and functionally. This ecosystem experiences highly complex networks of interactions, but may also present functionally independent entities. Plant roots, a metabolically active hotspot in the soil, take an essential part in shaping the rhizosphere. Tracking the dynamics of root-microbe interactions at high ...
    Quantification of the Humidity Effect on HR by Ion Leakage Assay
    Authors:  Musoki Mwimba and Xinnian Dong, date: 04/05/2019, view: 1246, Q&A: 0
    [Abstract] We describe a protocol to measure the contribution of humidity on cell death during the effector-triggered immunity (ETI), the plant immune response triggered by the recognition of pathogen effectors by plant resistance genes. This protocol quantifies tissue cell death by measuring ion leakage due to loss of membrane integrity during the ...
    Peptide Feeding and Mechanical Wounding for Tomato Seedlings
    Authors:  Lei Wang, Yan Wang and Georg Felix, date: 03/20/2019, view: 1894, Q&A: 0
    [Abstract] Plants need to respond appropriately to wounding and herbivorous insects. Peptide signals have been implicated in local and systemic induction of appropriate plant defense responses. To study these peptide signals and their perception in host plants, it is important to have reproducible bioassays. Several assays, such as treatment of peptide ...
