A Simplified Method to Assay Protein Carbonylation by Spectrophotometry as a hallmark of oxidative stress, the level of protein carbonylation being an indicator of the oxidative cellular status. The method described herein represents an adaptation to the commonly used 2,4-dinitrophenylhydrazine (DNPH)-based spectrophotometric method to monitor protein carbonylation lev

Methods to Analyze the Redox Reactivity of Plant Proteinsodifications of sensitive cysteine thiol groups in proteins impact protein characteristics such as interaction behavior and activity state. Evaluating the response of proteins to redox perturbation or reactive chemical species is critical for understanding the underlying mechanisms involved and thei

Measuring Stress-Induced Changes in Defense Phytohormones and Related Compoundsgulate stress responses. In this chapter, we describe the liquid chromatography-mass spectrometry procedure that we use to extract and quantify salicylic acid (SA), jasmonic acid (JA), and related compounds in common extracts of . tissue. The method can provide quantitative data on SA, SA glucosides

A Simplified Method to Assay Protein Carbonylation by Spectrophotometryel. The classical final sample precipitation was replaced by a gel filtration step avoiding the tedious and repetitive washings of the protein pellet to remove free DNPH while allowing optimal protein recovery..This improved protocol here implemented to assay protein carbonylation in plant leaves can potentially be used with any cellular extract.

Genetic Manipulation of Reactive Oxygen Species (ROS) Homeostasis Utilizing CRISPR/Cas9-Based Gene E construction of Cas9/sgRNA, agrobacterium-mediated transformation, and mutation characterization are described. Application of this system in editing a rice catalase gene ., a key antioxidative enzyme in controlling ROS homeostasis, is also presented.
