Cytochrome P450s (CYPs) are the largest enzyme family involved in NADPH-and/or O2-
dependent hydroxylation reactions across all the domains of life. In plants and animals …

Abstract Hydrogen peroxide (H2O2) is an important signal molecule involved in plant
development and environmental responses. Changes in H2O2 availability can result from …

Iron is essential for both plant productivity and nutritional quality. Improving plant iron
content was attempted through genetic engineering of plants overexpressing ferritins …

Significance: In photosynthetic organisms, excited chlorophylls (Chl) can stimulate the
formation of singlet oxygen (1O2), a highly toxic molecule that acts in addition to its …

The chloroplast is a complex cellular organelle that not only performs photosynthesis but
also synthesizes amino acids, lipids, and phytohormones. Nuclear and chloroplast genetic …

In this review, I outline the indirect evidence for the formation of singlet oxygen (1O2)
obtained from experiments with the isolated PSII reaction center complex. I also review the …

Two durum (Triticum durum L.), Barakatli-95 and Garagylchyg-2; and two bread (Triticum
aestivum L.) wheat cultivars, Azamatli-95 and Giymatli-2/17 with different sensitivities to …

Reactive oxygen species (ROS) have long been recognized as compounds with dual roles.
They cause cellular damage by reacting with biomolecules but they also function as agents …

Significance: The redox regulatory signaling network of the plant cell controls and co-
regulates transcriptional activities, thereby enabling adjustment of metabolism and …

Abstract The GENOMES UNCOUPLED4 (GUN4) protein stimulates chlorophyll biosynthesis
by activating Mg-chelatase, the enzyme that commits protoporphyrin IX to chlorophyll …
