Mechanisms of oxidative stress in plants: From classical chemistry to cell biology
TL;DR: This review revises primary mechanisms underlying plant oxidative stress at the cellular level through the use of directed evolution techniques to prevent protein oxidation, bioengineering of antioxidant activities as well as modification of ROS sensing mechanisms.
Journal ArticleDOI
Learning the Languages of the Chloroplast: Retrograde Signaling and Beyond
TL;DR: New findings on the processes by which organelle communication is initiated, transmitted, and perceived are discussed, not only to regulate chloroplastic processes but also to intersect with cellular signaling and alter physiological responses.

Muhammad Ansar Farooq,Adnan Khan Niazi,Javaid Akhtar,Saifullah,Muhammad Farooq,Zahra Souri,Naser Karimi,Zed Rengel +7 more
TL;DR: A comprehensive view of cellular ROS dynamics covering the breadth and versatility of ROS will contribute to understanding the complexity of apparently contradictory ROS roles in plant physiological responses in less than optimum environments.
Journal ArticleDOI
Retrograde signaling: Organelles go networking.
TL;DR: Recent advances in the identification and characterization of retrograde signaling components are reviewed, with particular emphasis on the strategies employed to define signaling components, spanning the entire spectrum of genetic screens, metabolite profiling and bioinformatics.
Journal ArticleDOI
Specificity in ROS signaling and transcript signatures.
TL;DR: Due to the difficulty of inducing ROS production specifically with regard to ROS type, subcellular localization, and timing, it is proposed that the concept of a "ROS marker gene" should be re-evaluated and guidelines for the analysis of transcriptional data in ROS signaling are suggested.

TL;DR: Correlation coefficients between the different antioxidant parameters and metal dose level, or dry matter accumulation, were established, assessing for an induced-oxidative stress and comparing the sensitivity of the two cultivars.
