    Pipecolic Acid Quantification Using Gas Chromatography-coupled Mass Spectrometry
    Authors:  Keshun Yu, Huazhen Liu and Pradeep Kachroo, date: 12/05/2020, view: 1200, Q&A: 0

    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

    Insect Feeding Assays with Spodoptera exigua on Arabidopsis thaliana
    Authors:  Yanrong You, Chunpeng An and Chuanyou Li, date: 03/05/2020, view: 2121, Q&A: 0
    [Abstract] Plant-insect interaction is an important field for studying plant immunity. The beet armyworm, Spodoptera exigua, is one of the best-known agricultural pest insects and is usually used to study plant interactions with chewing insects. Here, we describe a protocol for insect feeding assays with Spodoptera exigua lavae using model ...
    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: 4134, 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: 3180, 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: 3595, 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 ...
    Real-time PCR Analysis of PAMP-induced Marker Gene Expression in Nicotiana benthamiana
    Authors:  Fan Liu, Yuanpeng Xu, Yan Wang and Yuanchao Wang, date: 10/05/2018, view: 5120, Q&A: 0
    [Abstract] Perception of pathogen-associated molecular patterns (PAMPs) often triggers various innate immune responses in plants. The transcriptional changes of defense-related genes are often used as a marker to assay PAMP-triggered plant immune response. Here we described a protocol to monitor the relative expression level of marker genes in Nicotiana ...
    Transient Expression Assay in NahG Arabidopsis Plants Using Agrobacterium tumefaciens
    Authors:  Pepe Cana-Quijada, Eduardo R. Bejarano, Rosa Lozano-Durán and Tábata Rosas-Díaz, date: 06/20/2018, view: 6183, Q&A: 1
    [Abstract] Agrobacterium-mediated transient expression has greatly contributed to research in molecular plant biology but has low efficiency and inconsistency in Arabidopsis thaliana (Arabidopsis). Here, we describe a simple, efficient and fast protocol to make transient gene expression in NahG Arabidopsis plants using ...
    Quantification of Thrips Damage Using Ilastik and ImageJ Fiji
    Authors:  Isabella G. S. Visschers, Nicole M. van Dam and Janny L. Peters, date: 04/20/2018, view: 6912, Q&A: 0
    [Abstract] Quantification of insect damage is an essential measurement for identifying resistance in plants. In screening for host plant resistance against thrips, the total damaged leaf area is used as a criterion to determine resistance levels. Here we present an objective novel method for analyzing thrips damage on leaf disc using the freely available ...
    Haustorium Induction Assay of the Parasitic Plant Phtheirospermum japonicum
    Authors:  Juliane K. Ishida, Satoko Yoshida and Ken Shirasu, date: 05/05/2017, view: 6984, Q&A: 0
    [Abstract] Phtheirospermum japonicum is a facultative root parasitic plant in the Orobanchaceae family used as a model parasitic plant. Facultative root parasites form an invasive organ called haustorium on the lateral parts of their roots. To functionally characterize parasitic abilities, quantification of haustorium numbers is required. However, ...
    Bioassays to Investigate the Effects of Insect Oviposition on a Plant’s Resistance to Herbivores
    Authors:  Michele Bandoly and Anke Steppuhn, date: 06/05/2016, view: 10332, Q&A: 0
    [Abstract] Plants respond to herbivory with diverse defence responses (Schoonhoven et al., 2005). Many herbivorous insects deposit their eggs on their host plants before their larvae start to feed. Thus, plants could use insect eggs as a signal to increase their resistance to herbivores. Here, we report experimental procedures to explore whether and ...
