Abstract Cells are central for life, starting some 3.7 billion years ago with the assembly of first primordial cells in primeval and prebiotic oceans young Earth’s environment.

Some two after emergence Earth, eukaryotic were symbiotically assembled from archaeal bacterial Eukaryotic later coalesced form true multicellular partnership archaea, forming holobionts, including fungi, plants, animals.

Redox organization governs an underlying simplicity in living systems. Critically, redox reactions enable the essential characteristics of life: extraction energy from environment, use to support metabolic and structural organization, dynamic responses defend against environmental threats, mechanisms direct differentiation cells organ systems for reproduction. These processes are sustained through a context which electron donor/acceptor couples poised at substantially different steady-state potentials, some with relatively reducing steady states others oxidizing states. Redox-sensitive thiols proteome, as well low molecular weight redox-active molecules, maintained individually by kinetics oxidation-reduction within this system.

Abstract During their lifespan, plants are often exposed to a broad range of stresses that change redox balance and lead accumulation reactive oxygen species (ROS). The traditional view is this comes with negative consequences cells structural integrity metabolism and, prevent this, evolved complex well-coordinated antioxidant defence system relies on the operation enzymatic non-enzymatic antioxidants (AO). Due simplicity measuring activity, in light persistent dogma stress-induced ROS detrimental for plants, it not surprising AOs have been advocated as suitable proxies stress tolerance well potential targets improving traits. However, there growing number reports showing either no changes or even down-regulation AO systems stressed plants. Moreover, recognized now important second messengers operating both local systemic signalling, synergistically interacting primary stressor, regulate gene expression needed optimal acclimatization. This work critically assesses suitability using proxy target crop genetic improvement. It concluded constitutively higher activity may interfere signalling be disadvantage plant tolerance.

Phytophagous mites are herbivores that feed on various economically important plants, such as soybean [Glycine max (L.) Merril]. Thus, our objective is to evaluate the oxidative stress stage of plants infested by Tetranychus ludeni Zacher. Leaflets from three trifoliate leaves were pooled form composite samples for each exposure time and evaluated at following evaluation times: 0 h, 20 min, 6 12 24 48 h. In initial phase infestation (20 min), an burst was observed, represented prominent hydrogen peroxide accumulation rather than superoxide radicals. This occurred in parallel a strong increase antioxidant activities catalase, ascorbate peroxidase, glutathione S-transferase, but not dismutase. These changes likely reflected enhanced activation signaling pathways involved response. After this phase, min decrease S-transferases activities, despite levels remaining significantly elevated, along with marked transient reduced content proline. Interestingly, dismutase activity increased after h lipid peroxidation, whereas remained elevated until infestation. By final evaluation, infestation, some redox indicators altered relation control state moderate stress. unprecedented way, data suggest T. triggered response plants. findings highlight proper monitoring management can reduce economic losses without resorting aggressive chemical interventions.

Abstract NADPH‐dependent thioredoxin reductase C (NTRC) plays a central role in redox regulation of chloroplast photosynthetic metabolism. Accordingly, Arabidopsis ( thaliana ) NTRC‐null mutants show defective performance and growth inhibition. Remarkably, these almost wild‐type phenotype at the seedling stage, which raises question whether NTRC different functions throughout plant development. In this work, we have addressed issue by performing transcriptome comparisons ntrc mutant lines adult stages contrast with high impact on leaves from plants, low transcriptomic differences seedlings suggested less relevant function stage Notably, showed changes resembling response to Fe excess development, though was unique stage. The lack caused altered levels Mn, Zn, Cu, S, P, K Na, but no significant content Fe, as compared wild type. Moreover, hypersensitivity deficit protective effect excess, most likely due lower ROS accumulation seedlings. Our results reveal impacts development identify homeostasis process highly affected NTRC, notably

Plants are directly exposed to several biotic factors. Among these, mite species belonging the superfamilies Eriophyoidea and Tetranychoidea stand out due their ability injure or even transmit viruses host plants. In response infestations by these organisms, reactive oxygen (ROS), regulated enzymatic non-enzymatic antioxidants (homeostasis), can act as signaling molecules induce defenses acclimatization in attacked However, depending on severity of stress, there be an imbalance between ROS that result oxidative leading membrane damage lipid peroxidation, organelle inactivation, cell death. this review, we outline for first time current state understanding regarding role cellular processes metabolism, such signaling, potential induced ROS, defense antioxidant systems involved plant–mite relationship. Furthermore, identify gaps redox metabolism plant against phytophagous mites.
