Drought, a significant environmental challenge, presents substantial risk to worldwide agriculture and the security of food supplies. In response, plants can perceive stimuli from their environment activate defense pathways via various modulating networks cope with stress. Drought tolerance, multifaceted attribute, be dissected into distinct contributing mechanisms factors. Osmotic stress, dehydration dysfunction plasma endosome membranes, loss cellular turgidity, inhibition metabolite synthesis, energy depletion, impaired chloroplast function, oxidative stress are among most critical consequences drought on plant cells. Understanding intricate interplay these physiological molecular responses provides insights adaptive strategies employ navigate through Plant cells express withstand reverse effects These include osmotic adjustment preserve turgor, synthesis protective proteins like dehydrins, triggering antioxidant systems counterbalance A better understanding tolerance is crucial for devising specific methods improve crop resilience promote sustainable agricultural practices in environments limited water resources. This review explores employed by address challenges

Antioxidant Agriculture for Stress-Resilient Crop Production: Field Practice

Antioxidants, Год журнала: 2024, Номер 13(2), С. 164 - 164

Опубликована: Янв. 27, 2024

Oxidative stress, resulting from the excessive production of reactive oxygen species, is a common and major cause cellular damage in plants exposed to various abiotic stresses. To address this challenge, we introduce concept antioxidant agriculture as comprehensive strategy improve stress tolerance thus crop productivity by minimizing oxidative levels field environment. This encompasses diverse range approaches, including genetic engineering, exogenous application agents, microbial inoculation, agronomic practices, reinforce plant’s intrinsic defense system mitigate stress. We present recent successful studies measures that have been validated conditions, along with our perspective on achieving agriculture.

Decreasing nitrogen (N) supply affected the normal growth of Oryza sativa (O. sativa) seedlings, reducing CO2 assimilation, stomatal conductance (gs), contents chlorophylls (Chl) and ratio Chl a/Chl b, but increasing intercellular concentration. Polyphasic chlorophyll a fluorescence transient relative parameters (JIP test) results indicated that N deficiency increased Fo, decreased maximum quantum yield primary photochemistry (Fv/Fm) IPphase, implying N-limiting condition impaired whole photo electron transport chain from donor side photosystem II (PSII) to end acceptor PSI in O. sativa. enhanced activities antioxidant enzymes, such as ascorbate peroxidase (APX), guaiacol (GuPX), dehydro–ascorbate reductase (DHAR), superoxide dismutase (SOD), glutathione (GlPX), (GR), S-transferase (GST) O-acetylserine (thiol) lyase (OASTL), compounds including reduced (GSH), total (GSH+GSSG) non-protein thiol leaves. In contrast, catalase (CAT), DHAR, GR, GST OASTL, ASC–GSH cycle content sulfur-containing might provide protective roles against oxidative stress roots under conditions.
