TLDR
All three cultivars showed quick responses to aphid infestation by increasing polyphenol oxidase and phenylalanine ammonia lyase activities during the early period after inoculation, suggesting involvement of these two enzymes in aphid resistance.About:

TL;DR: By understanding the mechanisms of induced resistance, this work can predict the herbivores that are likely to be affected by induced responses and could be exploited as an important tool for the pest management to minimize the amounts of insecticides used for pest control.

Effects of shade treatments on photosynthetic characteristics, chloroplast ultrastructure, and physiology of Anoectochilus roxburghii.
TL;DR: Modulation of chloroplast development, accomplished by increasing the number of thylakoids and grana containing photosynthetic pigments, is an important shade tolerance mechanism in A. roxburghii.

Jasmonic Acid-Mediated-Induced Resistance in Groundnut (Arachis hypogaea L.) Against Helicoverpa armigera (Hubner) (Lepidoptera: Noctuidae)
TL;DR: It is concluded that pretreatment with JA and its application during low levels of insect infestation can increase the levels of host plant resistance against herbivorous insects and reduce the pest-associated losses in groundnut.

Defense Responses in Rice Induced by Silicon Amendment against Infestation by the Leaf Folder Cnaphalocrocis medinalis.
TL;DR: The results show that Si addition enhances rice resistance to the leaf folder through priming the feeding stress defense system, reduction in soluble protein content and cell silicification of rice leaves.

A rapid and sensitive method for the quantitation of microgram quantities of protein utilizing the principle of protein-dye binding
TL;DR: This assay is very reproducible and rapid with the dye binding process virtually complete in approximately 2 min with good color stability for 1 hr with little or no interference from cations such as sodium or potassium nor from carbohydrates such as sucrose.

REACTIVE OXYGEN SPECIES: Metabolism, Oxidative Stress, and Signal Transduction
Klaus Apel,Heribert Hirt +1 more
TL;DR: The mechanisms of ROS generation and removal in plants during development and under biotic and abiotic stress conditions are described and the possible functions and mechanisms for ROS sensing and signaling in plants are compared with those in animals and yeast.

Redox homeostasis and antioxidant signaling: a metabolic interface between stress perception and physiological responses.
Christine H. Foyer,Graham Noctor +1 more
TL;DR: Growing evidence suggests a model for redox homeostasis in which the reactive oxygen species (ROS)–antioxidant interaction acts as a metabolic interface for signals derived from metabolism and from the environment.

Active Oxygen Species in Plant Defense against Pathogens.
TL;DR: Observations indicate that there is an ongqing evolution of the host plant's ability to recognize pathogen races that were previously unrecognized while the pathogen evolves to avoid recognition by a previously resistant host.
