    I Plate-based Assay for Studying How Fungal Volatile Compounds (VCs) Affect Plant Growth and Development and the Identification of VCs via SPME-GC-MS
    Authors:  Wenzhao Wang, Ningxiao Li, Xingzhong Liu and Seogchan Kang, date: 02/20/2019, view: 1560, Q&A: 0
    [Abstract] Biogenic volatile compounds (VCs) mediate various types of crucial intra- and inter-species interactions in plants, animals, and microorganisms owing to their ability to travel through air, liquid, and porous soils. To study how VCs produced by Verticillium dahliae, a soilborne fungal pathogen, affect plant growth and development, we ...
    Measurement of Arabidopsis thaliana Plant Traits Using the PHENOPSIS Phenotyping Platform
    [Abstract] High-throughput phenotyping of plant traits is a powerful tool to further our understanding of plant growth and its underlying physiological, molecular, and genetic determinisms. This protocol describes the methodology of a standard phenotyping experiment in PHENOPSIS automated platform, which was engineered in INRA-LEPSE ( ...
    Transient Gene Expression for the Characteristic Signal Sequences and the Estimation of the Localization of Target Protein in Plant Cell
    [Abstract] We have proposed and tested a method for characterization of the signal sequences and determinations of target protein localization in a plant cell. This method, called the AgI-PrI, implies extraction of protoplasts from plant tissues after agroinfiltration. The suggested approach combines the advantages of two widely used methods for transient ...
    Real-time Analysis of Auxin Response, Cell Wall pH and Elongation in Arabidopsis thaliana Hypocotyls
    Authors:  Lanxin Li, S. F. Gabriel Krens, Matyáš Fendrych and Jiří Friml, date: 01/05/2018, view: 3628, Q&A: 0
    [Abstract] The rapid auxin-triggered growth of the Arabidopsis hypocotyls involves the nuclear TIR1/AFB-Aux/IAA signaling and is accompanied by acidification of the apoplast and cell walls (Fendrych et al., 2016). Here, we describe in detail the method for analysis of the elongation and the TIR1/AFB-Aux/IAA-dependent auxin response in ...
    Assessing Plant Tolerance to Acute Heat Stress
    Authors:  Minsoo Kim, Fionn McLoughlin, Eman Basha and Elizabeth Vierling, date: 07/20/2017, view: 5402, Q&A: 1
    [Abstract] It is well-established that plants are able to acclimate to temperatures above or below the optimal temperature for their growth. Here, we provide protocols for assays that can be used quantitatively or qualitatively to assess the relative ability of plants to acquire tolerance to high temperature stress. The hypocotyl elongation assay described ...
    Non-invasive Protocol for Kinematic Monitoring of Root Growth under Infrared Light
    [Abstract] Phenotyping the dynamics of root responses to environmental cues is necessary to understand plant acclimation to their environment. Continuous monitoring of root growth is challenging because roots normally grow belowground and are very sensitive to their growth environment. This protocol combines infrared imaging with hydroponic cultivation for ...
    Determination of the Effects of Local and Systemic Iron Excess on Lateral Root Initiation in Arabidopsis thaliana
    Authors:  Guangjie Li, Lin Zhang and Weiming Shi, date: 07/05/2017, view: 3352, Q&A: 0
    [Abstract] Root system architecture depends on nutrient availability. A symptom of iron (Fe) toxicity in plants is stunted root growth, yet little is known about the effects of excess Fe on lateral root (LR) development. To better understand how nutrient signals are integrated into root developmental programs, we investigated the morphological response of ...
    Forest GPP Calculation Using Sap Flow and Water Use Efficiency Measurements
    Authors:  Fyodor Tatarinov, Eyal Rotenberg, Dan Yakir and Tamir Klein, date: 04/20/2017, view: 4233, Q&A: 0
    [Abstract] This is a protocol to evaluate gross primary productivity (GPP) of a forest stand based on the measurements of tree’s sap flow (SF), 13C derived water use efficiency (WUE), and meteorological (met) data. GPP was calculated from WUE and stomatal conductance (gs), the later obtained from SF up-scaled from sampled trees to stand ...
    Establishment of New Split-root System by Grafting
    Authors:  Xiangqiang Kong, Zhen Luo and Hezhong Dong, date: 02/20/2017, view: 4801, Q&A: 0
    [Abstract] A new split-root system was used to simulate non-uniform salt, drought or nutrient deficiency stress in the root zone, in which the root system was divided into two or more equal portions. Here, we established a split-root system by grafting of cotton seedlings. In contrast to the conventional split-root, the main roots of the new system remained ...
    Protocol for Increasing Carotenoid Levels in the Roots of Citrus Plants
    Authors:  Matías Manzi, Marta Pitarch-Bielsa, Vicent Arbona and Aurelio Gómez-Cadenas, date: 12/20/2016, view: 4449, Q&A: 0
    [Abstract] Carotenoids in plants play several key functions such as acting as light-harvesters, antioxidants (Lado et al., 2016) or being precursors of strigolactones, abscisic acid, volatiles and other signaling compounds (Arbona et al., 2013). Although those functions are well-known in light-exposed tissues, information in belowground ...
