“…The non-enzymatic antioxidants include betalain, carotenoids, tocopherols, ascorbic acids, different phenolic and flavonoid compounds such as simple phenols, different hydroxybenzoic acids and hydroxycinnamic acids, flavanols, flavonols, flavones, flavanones, etc. have high radical quenching capacity [113][114][115][116][117][118][119]. Under abiotic stresses including drought and salinity, plant evolved mechanisms or pathways to enhance the accumulation of these non-enzymatic antioxidants for detoxifying the ROS [120,121].…”

Among abiotic stresses, salinity is a major global threat to agriculture, causing severe damage to crop production and productivity. Potato (Solanum tuberosum) is regarded as a future food crop by FAO to ensure food security, which is severely affected by salinity. The growth of the potato plant is inhibited under salt stress due to osmotic stress-induced ion toxicity. Salinity-mediated osmotic stress leads to physiological changes in the plant, including nutrient imbalance, impairment in detoxifying reactive oxygen species (ROS), membrane damage, and reduced photosynthetic activities. Several physiological and biochemical phenomena, such as the maintenance of plant water status, transpiration, respiration, water use efficiency, hormonal balance, leaf area, germination, and antioxidants production are adversely affected. The ROS under salinity stress leads to the increased plasma membrane permeability and extravasations of substances, which causes water imbalance and plasmolysis. However, potato plants cope with salinity mediated oxidative stress conditions by enhancing both enzymatic and non-enzymatic antioxidant activities. The osmoprotectants, such as proline, polyols (sorbitol, mannitol, xylitol, lactitol, and maltitol), and quaternary ammonium compound (glycine betaine) are synthesized to overcome the adverse effect of salinity. The salinity response and tolerance include complex and multifaceted mechanisms that are controlled by multiple proteins and their interactions. This review aims to redraw the attention of researchers to explore the current physiological, biochemical and molecular responses and subsequently develop potential mitigation strategies against salt stress in potatoes.

“…Besides, elevated nutrient levels can alter food plant quality and directly loop back on the fitness of some moth species ( Kurze et al 2018 ). Finally, subsidence induced soil salinity ( Antonellini and Mollema 2010 ) also might reduce food plant quality ( Okon 2019 ). Elevated salt content in soil may influence the composition and structure of the mycorrhiza and can lead to the decline of mature trees ( Montecchio et al 2004 ).…”

Long-term data are important to understand the changes in ecological communities over time but are quite rare for insects. We analyzed such changes using historic museum collections. For our study area, an isolated forest reserve in North-East Italy, data from the past 80 yr were available. We used records of 300 moth species to analyze whether extinction risk was linked to their body size or to their degree of ecological specialization. Specialization was scored 1) by classifying larval food affiliations, habitat preferences, and the northern distributional limit and 2) by analyzing functional dispersion (FDis) within species assemblages over time. Our results show that locally extinct species (mean wingspan: 37.0 mm) were larger than persistent (33.2 mm) or previously unrecorded ones (30.7 mm), leading to a smaller mean wingspan of the moth community over time. Some ecological filters appear to have selected against bigger species. By using coarse specialization categories, we did not observe any relationship with local extinction risk. However, FDis, calculated across 12 species traits, significantly decreased over time. We conclude that simple classification systems might fail in reflecting changes in community-wide specialization. Multivariate approaches such as FDis may provide deeper insight, as they reflect a variety of ecological niche dimensions. With the abandonment of extensive land use practices, natural succession seems to have shifted the moth community toward a preponderance of forest-affiliated species, leading to decreased FDis values. Multivariate analyses of species composition also confirmed that the moth community has significantly changed during the last 80 yr.

“…Saline land is suboptimal land that can inhibit and disrupt crop growth and production which is increasing in area and it assumption that 50% of the soil is affected by salinity in the next 50 years [1][2][3][4][5]. Plants are affected by salinity as a complex interaction between morphological and biochemical and physiological processes including seed germination, plant growth, and nutrient carryng [2][3].…”

The study for investigate the level production and growth for several varieties of paddy rice on washed saline land with microbial consortium treatment. The environmental design used factorial Randomized Group Design. The microbial consortium application (no microbial application, microbial application A, microbial application B, microbial application C), while the second factor of paddy rice varieties (Pokkali, Biosalin 2 Agritan, IR 29) and repeated three times. The data obtained were analyzed with the F test. If significantly different, then further test was conducted using DMRT 5%. The results showed that bleaching using fresh water decreased the value of electrical conductivity. The interaction between the treatment of the type of microbial consortium and the variety of paddy rice did not affect all observed variables, but the application of the type of microbial consortium independently differed between treatments on the growth component, namely the variable plant height and the best yield shown by Pokkali, while the production component had no effect. The treatment of the type of paddy rice varieties differed between treatments on both growth and production components and the best was Biosalin 2 Agritan of 5.80 tons.ha−1, IR 29 4.37 tons.ha−1, and Pokkali 2.96 tons.ha−1.
