The Arabidopsis thaliana aldehyde oxidase 3 (AAO3) catalyzes the oxidation of abscisic (ABal) to acid (ABA). Besides ABal, plants generate other aldehydes that can be toxic above a certain threshold. AAO3 knockout mutants (aao3) exhibited earlier senescence but equivalent relative water content compared with wild-type (WT) during normal growth or upon application UV-C irradiation. Aldehyde profiling in leaves 24-day-old revealed higher accumulation acrolein, crotonaldehyde, 3Z-hexenal,...
The accumulation of salt in arable lands is a source significant abiotic stress, contributing to 10% decline the world’s total and threatening food productivity sustainability agriculture. About 76 million hectares productive land are estimated have been affected by human-induced salinization such as extreme deposits soil, which mainly caused actions humans. For instance, continued irrigation frequent use chemical fertilizers need be understood. To ensure availability, it essential improve...
Abstract The roles of cytosolic O-acetylserine-(thiol)-lyase A (OASTLA), chloroplastic OASTLB, and mitochondrial OASTLC in plant selenate resistance were studied Arabidopsis. Impairment OASTLA OASTLB resulted reduced biomass, chlorophyll soluble protein content compared with selenate-treated OASTLC-impaired wild-type plants. generally lower total selenium (Se), protein-Se, organic-sulfur protein-sulfur (S) oastlA oastlB oastlC leaves indicated that Se accumulation was not the main cause for...
Molybdenum enzymes (Mo-enzymes) contain a molybdenum cofactor (MoCo) in the active site. These are potentially interesting for studying survival mechanism of fish under hypoxic water conditions. This is because Mo-enzymes can synthesize nitric oxide from nitrates and nitrites, which present high concentrations However, there currently no method assessing content internal organs. Methods capable determining major importance. For this purpose, quantitative determination MoCo plant tissues was...
The growing global demand for fish necessitates the exploration of sustainable aquaculture practices. This has led to a focus on quality and production products with minimal environmental impact. Thus, objective this review is study evaluate how different systems impact nutritional profile fish. Fish are rich sources protein, containing almost 20% protein essential amino acids vitamins. value directly related conditions under which they produced through aquaculture. article considers various...
SUMMARY Abiotic stress‐induced reactive carbonyl species (RCS) accumulation in plants stimulates oxidative stress by DNA adduct formation, protein carbonylation, and antioxidant pool depletion, triggering senescence or programmed cell death. RCS under abiotic has rarely been studied halophytic that are adapted to highly saline environments. In the current study, exposure UV‐C irradiation resulted a higher Sarcocornia fruticosa ecotypes VM EL than Salicornia brachiata (SB) Arthrocnemum...
This study examines the epidemiological situation of tuberculosis (TB) in regions Republic Kazakhstan over past seven years (2018–2024), which cover before-, during- and after-COVID-19 periods, with a focus on risks its emergence spread. The analysis revealed that while TB incidence is declining, mortality remains high before- during-COVID-19 indicating general decline population health. concentration relation to geographic location was mainly northern, western southern regions. Before...
Abstract Chloroplast-localized adenosine-5’-phosphosulphate reductase (APR) generates sulfite and plays a pivotal role in reduction of sulfate to cysteine. The peroxisome-localized oxidase (SO) oxidizes excess sulfate. Arabidopsis wild type, SO RNA-interference (SO Ri) overexpression OE) transgenic lines infiltrated with showed increased water loss Ri plants, smaller stomatal apertures OE plants compared wild-type plants. Sulfite application also limited abscisic acid-induced closure type...
The foliar feeding of soil-grown plants with essential elements such as molybdate can restore their Nitrate reductase activity. However, the activity nitrate under and in hydroponic conditions has not been investigated. Thus, we wanted to investigate effect on leaves lemon balm conditions. solutions were applied by spraying was determined colorimetric method. results our study demonstrated that application KNO3 solution enhanced plants. Importantly, indicate fertilization improve nitrogen...
Purine degradation products have been shown to play roles in plant response stresses such as drought, salinity, extended dark, nitrogen deficiency, and pathogen infection. In this study, we used Arabidopsis wild-type (WT) an Atxdh1-knockout mutant defective xanthine dehydrogenase1 (XDH1) examine the role of degraded purine metabolites responses wounding or UV-C stress applied middle leaves plant. Wounding resulted lower fresh-weight, increased senescence symptoms, cell death compared WT...
Molybdenum cofactor containing sulfite oxidase (SO) enzyme is an important player in protecting plants against exogenous toxic sulfite. It was also demonstrated that SO activity essential to cope with rising dark-induced endogenous levels and maintain optimal carbon sulfur metabolism tomato exposed extended dark stress. The response of reductase direct exposure low high sulfate rarely shown. By employing Arabidopsis wild-type, reductase, SO-modulated supplied excess or limited supply, the...
Salinity negatively influences crop growth, but several salt-tolerant plant species (halophytes) are viable crops. Sarcocornia fruticosa (ecotypes EL and VM) is currently cultivated, there demand for new candidates higher biomass production. Salicornia brachiata Roxb. Arthrocneum macrostachyum L. considered novel crops, to realize their potential, response salinity nitrogen nutrition was compared S. ecotypes. Experiments revealed that N supplemented with lower NaCl significantly increased...
Abstract To examine a role of purine degraded metabolites in response to wounding or UV-C stress, the Arabidopsis wild-type and Atxdh1 KO mutants, defective xanthine dehydrogenase1 (XDH1), were exposed irradiation stress. In mutant, stresses resulted lower fresh-weight, increased senescence symptoms higher tissue cell death rate compared Wild-type. Additionally, Wild-type exhibited levels oxidative stress indicators; reactive oxygen species malondialdehyde than mutant leaves. Notably,...
Among the three active aldehyde oxidases in Arabidopsis thaliana leaves (AAO1-3), AAO3, which catalyzes oxidation of abscisic-aldehyde to abscisic-acid, was shown recently function as a reactive detoxifier. Notably, aao2KO mutants exhibited less senescence symptoms and lower accumulation, such acrolein, benzaldehyde, 4-hydroxyl-2-nonenal (HNE) than wild-type exposed UV-C or Rose-Bengal. The effect AAO2 expression absence on detoxification by AAO3 and/or AAO1 studied comparing response plants...

Abstract Ureides, the degraded products of purine catabolism in Arabidopsis, have been shown to act as antioxidant and nitrogen sources. Herein we elucidate metabolites a carbon source using Arabidopsis Atxdh1, Ataln, Ataah knockout (KO) mutants vis-à-vis wild-type (WT) plants. Plants were grown under short-day conditions on agar plates containing half-strength MS medium with or without 1% sucrose. Notably, absence sucrose led diminished biomass accumulation both shoot root tissues mutants,...
