Simple Summary Environmental conditions are subject to unprecedented changes due to
recent progressive anthropogenic activities on our planet. Plants, as the frontline of food …

Catalase is a powerful antioxidant metalloenzyme located in peroxisomes which also plays
a central role in signaling processes under physiological and adverse situations. Whereas …

▪ Abstract The production of reactive oxygen species (ROS), such as O2− and H2O2, is an
unavoidable consequence of aerobic metabolism. In plant cells the mitochondrial electron …

We have taken advantage of an acclimation phenomenon in a chilling-sensitive maize
inbred to investigate the molecular, biochemical, and physiological responses to chilling in …

Catalases and peroxidases are the two major systems for the enzymic removal of hydrogen
peroxide (H202) in plants. Catalases dismutate H202 to H20 and 02 (2H202~ 2H20+ O2) …

The mechanisms by which the maize antioxidant Cat1 gene responds to abscisic acid (ABA)
and osmotic stress have been investigated. Results show that during late embryogenesis …

Rootstocks of fruit trees, commonly used to regulate growth, precocity, fertility, and yield, can
also be used to solve problems associated with soils pollution such as copper excess …

Chilling-enhanced photooxidation is the light-and oxygen-dependent bleaching of
photosynthetic pigments that occurs upon the exposure of chilling-sensitive plants to …

Publisher Summary This chapter discusses the genomic responses of plants to the oxidative
stress—particularly in maize. The chapter also discusses several mechanisms that the …

Codon usage is the selective and nonrandom use of synonymous codons by an organism to
encode the amino acids in the genes for its proteins. During the last few years, a large …
