From Lab to Field: Harnessing HO-Mediated Upregulation of Plant Capacities Under Abiotic Stresses.

Climate-driven abiotic stresses, responsible for approximately 50% of global crop yield losses, are putting agriculture under increasing pressure, demanding smarter ways to strengthen plants' natural defenses beyond genetic modification. Hydrogen peroxide (HO), long recognized as a key signaling molecule, plays a powerful role in helping plants cope with environmental stress. This review deciphers the mechanistic basis of HO-mediated capacity enhancement under diverse stresses (drought, salinity, heavy metals, heat, cold) while also addressing climate-intensified challenges like waterlogging and ultraviolet (UV) radiation.

Lipids and amino acids inhibitory herbicides impaired the leaf structure and photosynthetic capacity of wheat seedlings under elevated temperature.

Weeds management without herbicides seems impossible in modern day agriculture while, their phytotoxic effects on the crops are equally anticipated. However, the magnitude of herbicidal phytotoxicity on wheat seedlings in the perspective of global warming has predominantly remained unexplored. In the line of that, an experiment was conducted in which the wheat seedlings were raised in a high and normal temperature environment and treated with the amino and fatty acids synthesis inhibitory herbicides including Atlantis Super, Axial, and Puma Super along with a control.

Salinity and exogenous H O improve gas exchange, osmoregulation, and antioxidant metabolism in quinoa under drought stress.

Climate change-induced concurrent drought and salinity stresses significantly threaten global crop yields, yet the physio-biochemical responses to combined stress in quinoa remain elusive. This study evaluated quinoa responses under four growth conditions: well-watered, drought stress, salt stress, and drought + salt stress with (15 mM) or without (0 mM) exogenous hydrogen peroxide (H O ) application. All examined stresses (alone or in combination) reduce quinoa growth and net photosynthesis, although salt stress was found to be less destructive than drought and combined stress.

Impression of foliar-applied folic acid on coriander ( L.) to regulate aerial growth, biochemical activity, and essential oil profiling under drought stress.

Drought is one of the major environmental limitations in the crop production sector that has a great impact on food security worldwide. Coriander ( L.) is an herbaceous angiosperm of culinary significance and highly susceptible to rootzone dryness.

Groundwater Depths Affect Phosphorus and Potassium Resorption but Not Their Utilization in a Desert Phreatophyte in Its Hyper-Arid Environment.

Nutrients are vital for plant subsistence and growth in nutrient-poor and arid ecosystems. The deep roots of phreatophytic plants are necessary to access groundwater, which is the major source of nutrients for phreatophytes in an arid desert ecosystem. However, the mechanisms through which changes in groundwater depth affect nutrient cycles of phreatophytic plants are still poorly understood.

Synergistic consequences of salinity and potassium deficiency in quinoa: Linking with stomatal patterning, ionic relations and oxidative metabolism.

Quinoa emerged as an ideal food security crop due to its exceptional nutritive profile and stress enduring potential and also deemed as model plant to study the salt-tolerance mechanisms. However to fill the research gaps of this imperative crop, the present work aimed to study the effect of potassium (K) deficiency either separately or in combination with salinity. First, we investigated the stomatal and physiological based variations in quinoa growth under salinity and K, then series of analytical tools were used with model approach to interpret the stomatal aperture (SA) and photosynthesis (Pn) changes.

Differential physio-biochemical and yield responses of Camelina sativa L. under varying irrigation water regimes in semi-arid climatic conditions.

Camelina sativa L. is an oilseed crop with wide nutritional and industrial applications. Because of favorable agronomic characteristics of C.

Toxicological and morphological effects of tebufenozide on Anticarsia gemmatalis (Lepidoptera: Noctuidae) larvae.

The velvetbean caterpillar, Anticarsia gemmatalis Hübner (Lepidoptera: Noctuidae), is an important soybean pest in the Americas. Tebufenozide, a novel nonsteroidal ecdysone agonist is used to control this pest. Bioassays were conducted to assess tebufenozide toxicity and their ultrastructural effects on midgut of A.

Soil drenching of paclobutrazol: An efficient way to improve quinoa performance under salinity.

Salinity extent and severity is rising because of poor management practices on agricultural lands, possibility lies to grow salt-tolerant crops with better management techniques. Therefore, a highly nutritive salt-tolerant crop quinoa with immense potential to contribute for future food security was selected for this investigation. Soil drenching of paclobutrazol (PBZ; 20 mg l ) was used to understand the ionic relations, gaseous exchange characteristics, oxidative defense system and yield under saline conditions (400 mM NaCl) including normal (0 mM NaCl) and no PBZ (0 mg l ) as controls.

Differential response of quinoa genotypes to drought and foliage-applied HO in relation to oxidative damage, osmotic adjustment and antioxidant capacity.

Quinoa (Chenopodium quinoa Willd.), a highly nutritious grain crop, is resistant to abiotic stresses (drought, salinity, and cold) and offers an alternate crop to endure harsh environmental conditions under the face of climate change. Naturally, quinoa genome displays a wide degree of variabilities in drought tolerance strategies.

Groundwater Depth Affects Phosphorus But Not Carbon and Nitrogen Concentrations of a Desert Phreatophyte in Northwest China.

Ecological stoichiometry is an important aspect in the analysis of the changes in ecological system composition, structure, and function and understanding of plant adaptation in habitats. Leaf carbon (C), nitrogen (N), and phosphorus (P) concentrations in desert phreatophytes can be affected by different depths of groundwater through its effect on the adsorption and utilization of nutrient and plant biomass. We examined the biomass, soil organic C, available (mineral) N, and available P, and leaf C, N, and P concentrations of grown at varying groundwater depths of 2.
