Abstract Salicylic acid (SA) plays a key role in plant disease resistance and hypersensitive cell death but is also implicated hardening responses to abiotic stressors. Cadmium (Cd) exposure increased the free SA contents of barley (Hordeum vulgare) roots by factor about 2. Cultivation dry caryopses presoaked SA-containing solution for only 6 h or single transient addition at 0.5 mmconcentration hydroponics partially protected seedlings from Cd toxicity during following growth period. Both...
Transcription in plastids is mediated by a plastid-encoded multimeric (PEP) and nuclear-encoded single-subunit RNA polymerase (NEP) still unknown number of factors. By combining gel filtration affinity chromatography purification steps, we isolated transcriptionally active chromosomes from Arabidopsis thaliana mustard (Sinapis alba) chloroplasts identified 35 components electrospray ionization ion trap tandem mass spectrometry. Eighteen components, called plastid chromosome proteins (pTACs),...
Fifteen bacterial strains containing 1-aminocyclopropane-1-carboxylate (ACC) deaminase were isolated from the rhizoplane of pea (Pisum sativum L.) and Indian mustard (Brassica juncea grown in different soils a long-standing sewage sludge contaminated with heavy metals. The characterized assigned to various genera species, such as Pseudomonas brassicacearum, marginalis, oryzihabitans, putida, sp., Alcaligenes xylosoxidans, Variovorax paradoxus, Bacillus pumilus, Rhodococcus sp. by...
Abstract Nitric oxide (NO) is a free radical product of cell metabolism that plays diverse and important roles in the regulation cellular function. S-Nitrosylation emerging as specific fundamental posttranslational protein modification for transduction NO bioactivity, but very little known about its physiological functions plants. We investigated molecular mechanism S-nitrosylation peroxiredoxin II E (PrxII E) from Arabidopsis thaliana found this inhibits hydroperoxide-reducing peroxidase...
The jasmonate family of phytohormones plays central roles in plant development and stress acclimation. However, the architecture their signaling circuits remains largely unknown. Here we describe a binding protein, cyclophilin 20-3 (CYP20-3), which regulates stress-responsive cellular redox homeostasis. (+)-12-oxo-phytodienoic acid (OPDA) promotes CYP20-3 to form complex with serine acetyltransferase 1, triggers formation hetero-oligomeric cysteine synthase O -acetylserine(thiol)lyase B...
The 2-cysteine peroxiredoxins (2-Cys Prx) constitute an ancient family of peroxide detoxifying enzymes and have acquired a plant-specific function in the oxygenic environment chloroplast. Immunocytochemical analysis work with isolated intact chloroplasts revealed reversible binding oligomeric form 2-Cys Prx to thylakoid membrane. enzyme was enhanced under stress. has broad substrate specificity activity toward hydrogen peroxides complex alkyl hydroperoxides. During reduction reaction, is...
Abstract Peroxiredoxins (prxs) are peroxidases with broad substrate specificity. The seven prx genes expressed in Arabidopsis shoots were analyzed for their expressional response to changing photon fluence rates, oxidative stress, and ascorbate application. results reveal a highly variable gene-specific reducing oxidizing conditions. steady-state transcript amounts of the chloroplast-targeted prxs, namely two-cysteine (2-Cys) Q andprx II E, decreased upon application ascorbate.prx also...
