A Quick Method to Quantify Iron in Arabidopsis Seedlings

Authors: Chandan Kumar Gautam, Huei-Hsuan Tsai and Wolfgang Schmidt, date: 03/05/2022, view: 1123, Q&A: 0

[Abstract]

Iron (Fe) is an indispensable micronutrient for plant growth and development. Since both deficiency, as well as a surplus of Fe, can be detrimental to plant health, plants need to constantly tune uptake rates to maintain an optimum level of Fe. Quantification of Fe serves as an important parameter for analyzing the fitness of plants from different

MAMP-triggered Medium Alkalinization of Plant Cell Cultures

Authors: Gabriel L. Fiorin, Andrea Sánchez-Vallet, Bart P. H. J. Thomma, Gonçalo A. G. Pereira and Paulo J.P.L. Teixeira, date: 04/20/2020, view: 2718, Q&A: 0

[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 ...

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: 4541, 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 ...

An Inexpensive and Comprehensive Method to Examine and Quantify Field Insect Community Influenced by Host Plant Olfactory Cues

Authors: Rupesh Kariyat, Jesus Chavana and Jasleen Kaur, date: 08/20/2018, view: 4629, Q&A: 0

[Abstract] Insect pollinators, herbivores and their natural enemies use olfactory cues emitted by their host plants to locate them. In insect-plant ecology, understanding the mechanisms underlying these interactions are of critical importance, as this bio-communication has both ecological and agricultural applications. However, the first step in such ...

Analysis of Metals in Whole Cells, Thylakoids and Photosynthetic Protein Complexes in Synechocystis sp. PCC6803

Authors: Chiara Gandini, Søren Husted and Sidsel Birkelund Schmidt, date: 06/20/2018, view: 4453, Q&A: 0

[Abstract] Metals are essential in many biological processes, including oxygenic photosynthesis. Here we described a method to measure the metal pool in whole cells and thylakoids, including the bioactive pool in intact photosynthetic protein complexes in the model oxygenic cyanobacterium Synechocystis PCC6803. In the first part of the protocol, ...

In vitro Nitrate Reductase Activity Assay from Arabidopsis Crude Extracts

Authors: Joo Yong Kim and Hak Soo Seo, date: 04/05/2018, view: 8403, Q&A: 0

[Abstract] Nitrate reductase (NR) reduces the major plant nitrogen source, NO₃^-, into NO₂^-. NR activity can be measured by its final product, nitrite through its absorbance under optimized condition. Here, we present a detailed protocol for measuring relative enzyme activity of NR from Arabidopsis crude ...

Estimation of Silica Cell Silicification Level in Grass Leaves Using in situ Charring Method

Authors: Santosh Kumar and Rivka Elbaum, date: 11/20/2017, view: 6203, Q&A: 0

[Abstract] Silica cells are specialized leaf epidermal cells in grasses with almost the whole cell volume filled with solid silica. In sorghum, silica deposition in silica cells takes place in young, elongating leaves around the mid-length of the leaf. We developed a protocol for estimating the level of silica cell silicification in Sorghum bicolor ...

Extraction and Molybdenum Blue-based Quantification of Total Phosphate and Polyphosphate in Parachlorella

Authors: Shuhei Ota and Shigeyuki Kawano, date: 09/05/2017, view: 9006, Q&A: 0

[Abstract] Inorganic phosphorus is a non-renewable resource and an essential element for life on Earth. Organisms such as algae, protists, and animals can store phosphate (Pi) through uptake of Pi as polyphosphate (poly-P), which is a linear polymer of orthophosphate residues linked by high-energy phosphoanhydride bonds. Here, we describe procedures for ...

Determination of Reduced and Total Glutathione Content in Extremophilic Microalga Galdieria phlegrea

Authors: Giovanna Salbitani, Claudia Bottone and Simona Carfagna, date: 07/05/2017, view: 18846, Q&A: 3

[Abstract] Glutathione is an important molecule involved in the primary and secondary metabolism of all organisms. The Glutathione redox status is an indicator of the cellular redox state. Therefore, it is important to have precise methods on hand to determine the glutathione redox status in the cell. In this protocol, we describe an improved ...

Acetyl Bromide Soluble Lignin (ABSL) Assay for Total Lignin Quantification from Plant Biomass

Authors: William J. Barnes and Charles T. Anderson, date: 03/05/2017, view: 13680, Q&A: 0

[Abstract] Lignin is the second most abundant biopolymer on Earth, providing plants with mechanical support in secondary cell walls and defense against abiotic and biotic stresses. However, lignin also acts as a barrier to biomass saccharification for biofuel generation (Carroll and Somerville, 2009; Zhao and Dixon, 2011; Wang et al., 2013). For ...
