2001 article

Transgenic tobacco plants expressing the maize Cat2 gene have altered catalase levels that affect plant-pathogen interactions and resistance to oxidative stress

Polidoros, A. N., Mylona, P. V., & Scandalios, J. G. (2001, December 1). Transgenic Research.

By: A. Polidoros n, P. Mylona n & J. Scandalios n

author keywords: catalase; disease resistance; gene silencing; plant-pathogen interactions; reactive oxygen
MeSH headings : Blotting, Southern; Blotting, Western; Catalase / genetics; Catalase / metabolism; DNA, Complementary / metabolism; Genotype; Hydrogen Peroxide / metabolism; Oxidative Stress; Phenotype; Plant Proteins; Plants, Genetically Modified; RNA, Ribosomal, 18S / metabolism; Time Factors; Tobacco / enzymology; Tobacco / genetics; Tobacco / microbiology; Zea mays / genetics
topics (OpenAlex): Plant-Microbe Interactions and Immunity; CRISPR and Genetic Engineering; Plant Virus Research Studies
TL;DR: The data indicate that growth under high light conditions can predispose plants to better resist pathogen attack, and may amplify local and systemic defense signals. (via Semantic Scholar)

1999 article

Role of hydrogen peroxide and different classes of antioxidants in the regulation of catalase and glutathione S‐transferase gene expression in maize (Zea mays L.)

Polidoros, A. N., & Scandalios, J. G. (1999, May 1). Physiologia Plantarum.

By: A. Polidoros n & J. Scandalios n

topics (OpenAlex): Genomics, phytochemicals, and oxidative stress; Plant Stress Responses and Tolerance; Free Radicals and Antioxidants
TL;DR: A direct signaling action of H 2 O 2 is demonstrated in the regulation of antioxidant gene responses in maize, suggesting that ARE may play a role in the high induction of Cat1 in a tissue which, due to senescence, is under oxidative stress. (via Semantic Scholar)

1998 article

Modulation of antioxidant responses by arsenic in maize

Mylona, P. V., Polidoros, A. N., & Scandalios, J. G. (1998, September 1). Free Radical Biology and Medicine.

By: P. Mylona*, A. Polidoros n & J. Scandalios n

MeSH headings : Antioxidants; Arsenic / administration & dosage; Arsenic / pharmacology; Catalase / genetics; Catalase / metabolism; Gene Expression / drug effects; Glutathione Transferase / genetics; Isoenzymes / genetics; Isoenzymes / metabolism; RNA, Messenger / metabolism; Superoxide Dismutase / genetics; Superoxide Dismutase / metabolism; Zea mays / enzymology; Zea mays / genetics
topics (OpenAlex): Genomics, phytochemicals, and oxidative stress; Selenium in Biological Systems; Arsenic contamination and mitigation
TL;DR: The results indicate that arsenic triggers tissue and developmental stage specific defense responses of antioxidant and detoxification related genes in maize, as well as the activity of SOD and CAT enzymes. (via Semantic Scholar)
