    Monitoring Real-time Temperature Dynamics of a Short RNA Hairpin Using Förster Resonance Energy Transfer and Circular Dichroism
    Authors:  Martin Balcerowicz, Marco Di Antonio and Betty Y. W. Chung, date: 03/20/2021, view: 1149, Q&A: 0
    [Abstract]

    RNA secondary structures are highly dynamic and subject to prompt changes in response to the environment. Temperature in particular has a strong impact on RNA structural conformation, and temperature-sensitive RNA hairpin structures have been exploited by multiple organisms to modify the rate of translation in response to temperature changes.

    Plant ARGONAUTE Protein Immunopurification for Pathogen Cross Kingdom Small RNA Analysis
    Authors:  Florian Dunker, Bernhard Lederer and Arne Weiberg, date: 02/05/2021, view: 800, Q&A: 0
    [Abstract]

    Over the last decade, it has been noticed that microbial pathogens and pests deliver small RNA (sRNA) effectors into their host plants to manipulate plant physiology and immunity for infection, known as cross kingdom RNA interference. In this process, fungal and oomycete parasite sRNAs hijack the plant ARGONAUTE (AGO)/RNA-induced silencing complex

    RNA Stability Measurements Using RT-qPCR in Arabidopsis Seedlings
    Authors:  Tianran Jia and Brandon H. Le, date: 07/20/2020, view: 1489, Q&A: 0
    [Abstract] Steady-state mRNA levels are determined by both the rates of transcription and degradation. Regulation of mRNA stability and/or degradation are key factors that can significantly affect mRNA levels and its biological functions. mRNA stability can be measured indirectly after transcription inhibition. This protocol described a rapid and sensitive ...
    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: 4823, 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 ...
    In planta Transcriptome Analysis of Pseudomonas syringae
    Authors:  Tatsuya Nobori and Kenichi Tsuda, date: 09/05/2018, view: 5733, Q&A: 0
    [Abstract] Profiling bacterial transcriptome in planta is challenging due to the low abundance of bacterial RNA in infected plant tissues. Here, we describe a protocol to profile transcriptome of a foliar bacterial pathogen, Pseudomonas syringae pv. tomato DC3000, in the leaves of Arabidopsis thaliana at an early stage of ...
    Extraction of RNA from Recalcitrant Tree Species Paulownia elongata
    Authors:  Niveditha Ramadoss and Chhandak Basu, date: 07/20/2018, view: 4059, Q&A: 0
    [Abstract] Isolation of pure RNA is the basic requisite for most molecular biology work. Plants contain polyphenols and polysaccharides, which can interfere with isolation of pure RNA from them. Especially hardwood tree species like Paulownia elongata have surplus amount of RNA-binding alkaloids, proteins and secondary metabolites that can further ...
    RNA Purification from the Unicellular Green Alga, Chromochloris zofingiensis
    Authors:  Sean D. Gallaher and Melissa S. Roth, date: 04/05/2018, view: 4968, Q&A: 0
    [Abstract] Chromochloris zofingiensis is a unicellular green alga that is an emerging model species for studies in fields such as biofuel production, ketocarotenoid biosynthesis and metabolism. The recent availability of a high-quality genome assembly facilitates systems-level analysis, such as RNA-Seq. However, cells of this alga have a tough cell ...
    Isolation of Nuclei in Tagged Cell Types (INTACT), RNA Extraction and Ribosomal RNA Degradation to Prepare Material for RNA-Seq
    [Abstract] Gene expression is dynamically regulated on many levels, including chromatin accessibility and transcription. In order to study these nuclear regulatory events, we describe our method to purify nuclei with Isolation of Nuclei in TAgged Cell Types (INTACT). As nuclear RNA is low in polyadenylated transcripts and conventional pulldown methods would ...
    In vitro RNA-dependent RNA Polymerase Assay Using Arabidopsis RDR6
    Authors:  Kyungmin Baeg, Yukihide Tomari and Hiro-oki Iwakawa, date: 01/05/2018, view: 6769, Q&A: 0
    [Abstract] RNA-dependent RNA polymerases (RdRPs) in eukaryotes convert single-stranded RNAs into double-stranded RNAs, thereby amplifying small interfering RNAs that play crucial roles in the regulation of development, maintenance of genome integrity and antiviral immunity. Here, we describe a method of in vitro RdRP assay using recombinant ...
    Trimolecular Fluorescence Complementation (TriFC) Assay for Direct Visualization of RNA-Protein Interaction in planta
    Authors:  Jun Sung Seo and Nam-Hai Chua, date: 10/20/2017, view: 7780, Q&A: 0
    [Abstract] RNA-Protein interactions play important roles in various eukaryotic biological processes. Molecular imaging of subcellular localization of RNA/protein complexes in plants is critical for understanding these interactions. However, methods to image RNA-Protein interactions in living plants have not yet been developed until now. Recently, we have ...
