Thioredoxin Deficiency Causes the Constitutive Activation of Yap1, an AP-1-like Transcription Factor in Saccharomyces cerevisiae *
Yap1 is a transcription factor that responds to oxidative stress in Saccharomyces cerevisiae. The activity of Yap1 is regulated at the level of its intracellular localization, and a cysteine-richExpand

Differential Metabolisms of Green Leaf Volatiles in Injured and Intact Parts of a Wounded Leaf Meet Distinct Ecophysiological Requirements
Almost all terrestrial plants produce green leaf volatiles (GLVs), consisting of six-carbon (C6) aldehydes, alcohols and their esters, after mechanical wounding. C6 aldehydes deter enemies, but C6Expand

Protection against Photooxidative Injury of Tobacco Leaves by 2-Alkenal Reductase. Detoxication of Lipid Peroxide-Derived Reactive Carbonyls1
Degradation of lipid peroxides leads to the formation of cytotoxic 2-alkenals and oxenes (collectively designated reactive carbonyls). The novel NADPH-dependent oxidoreductase 2-alkenal reductaseExpand

Ascorbate in thylakoid lumen functions as an alternative electron donor to photosystem II and photosystem I.
The roles of ascorbate (Asc) in the thylakoid lumen to support photosynthetic electron transport are investigated. Asc can be photooxidized in photosystem (PS) II and PSI. When the water oxidaseExpand

The Involvement of Lipid Peroxide-Derived Aldehydes in Aluminum Toxicity of Tobacco Roots1[W][OA]
Oxidative injury of the root elongation zone is a primary event in aluminum (Al) toxicity in plants, but the injuring species remain unidentified. We verified the hypothesis that lipidExpand

Importance of glucose-6-phosphate dehydrogenase in the adaptive response to hydrogen peroxide in Saccharomyces cerevisiae.
Glucose-6-phosphate dehydrogenase (G6PDH)-deficient cells of Saccharomyces cerevisiae showed increased susceptibility and were unable to induce adaptation to oxidative stress. Historically, mainly inExpand

Identification of oxidatively modified proteins in salt-stressed Arabidopsis: a carbonyl-targeted proteomics approach.
In plants, environmental stresses cause an increase in the intracellular level of reactive oxygen species (ROS), leading to tissue injury. To obtain biochemical insights into this damage process, weExpand

Differential electron flow around photosystem I by two C4‐photosynthetic‐cell‐specific ferredoxins
In the C4 plant maize (Zea mays L.), two ferredoxin isoproteins, Fd I and Fd II, are expressed specifically in mesophyll and bundle‐sheath cells, respectively. cDNAs for these ferredoxins wereExpand

Characterization of raspberry ketone/zingerone synthase, catalyzing the alpha, beta-hydrogenation of phenylbutenones in raspberry fruits.
Phenylbutanone raspberry ketone, accumulating in the mature fruits of raspberry (Rubus idaeus), imparts the characteristic aroma to the fruits. Here we describe the isolation and characterization ofExpand

Lipid Peroxide-Derived Short-Chain Carbonyls Mediate Hydrogen Peroxide-Induced and Salt-Induced Programmed Cell Death in Plants1[OPEN]
Blocking accumulation of carbonyls derived from lipid peroxides is sufficient to block oxidative stress-triggered programmed cell death. Lipid peroxide-derived toxic carbonyl compounds (oxylipinExpand
