“…Treatment with SA in the vegetative stage of rice rescued the plants from hampered growth and development. Similar findings were also reported in other studies [ 31 ] where in Vicia faba L., SA improved photosynthesis and antioxidant response in planta [ 32 ]. SA also enhanced growth in other cereals under salt stress such as barley, wheat and maize [ 33 , 34 , 35 ].…”

Environmental or abiotic stresses are a common threat that remains a constant and common challenge to all plants. These threats whether singular or in combination can have devastating effects on plants. As a semiaquatic plant, rice succumbs to the same threats. Here we systematically look into the involvement of salicylic acid (SA) in the regulation of abiotic stress in rice. Studies have shown that the level of endogenous salicylic acid (SA) is high in rice compared to any other plant species. The reason behind this elevated level and the contribution of this molecule towards abiotic stress management and other underlying mechanisms remains poorly understood in rice. In this review we will address various abiotic stresses that affect the biochemistry and physiology of rice and the role played by SA in its regulation. Further, this review will elucidate the potential mechanisms that control SA-mediated stress tolerance in rice, leading to future prospects and direction for investigation.

“…Salicylic acid (SA) has been described as being able to increase the tolerance to abiotic stress in horticultural crops when applied exogenously. 18 We found that levels of SA were stable upon stress. Levels diverged about 2- to 3-fold between cultivars, but again, we did not observe a distinctive pattern between drought-tolerant and drought-sensitive cultivars ( Figure 7 D).…”

“…The comparison of the physiological and molecular responses among drought-tolerant and drought-sensitive populations to identify differential traits has proven to be a useful strategy to characterize the abiotic response of specific crops 17 , 18 or even forest species. 19 , 20 To apply this strategy to broccoli, we have identified drought-tolerant and drought-sensitive precommercial cultivars of this crop based on field and greenhouse experiments.…”

Broccoli is a cruciferous crop rich in health-promoting metabolites. Due to several factors, including anthropogenic global warming, aridity is increasing in many cultivation areas. There is a great demand to characterize the drought response of broccoli and use this knowledge to develop new cultivars able to maintain yield under water constraints. The aim of this study is to characterize the drought response at the physiological and molecular level of different broccoli ( Brassica oleracea L . var. Italica Plenck) cultivars, previously characterized as drought-sensitive or drought-tolerant. This approach aims to identify different traits, which can constitute limiting factors for drought stress tolerance in broccoli. For this purpose, we have compared several physiological parameters and the complete profiles of amino acids, primary metabolites, hormones, and ions of drought-tolerant and drought-sensitive cultivars under stress and control conditions. We have found that drought-tolerant cultivars presented higher levels of methionine and abscisic acid and lower amounts of urea, quinic acid, and the gluconic acid lactone. Interestingly, we have also found that a drought treatment increases the levels of most essential amino acids in leaves and in florets. Our results have established physiological and molecular traits useful as distinctive markers to predict drought tolerance in broccoli or which could be reliably used for breeding new cultivars adapted to water scarcity. We have also found that a drought treatment increases the content of essential amino acids in broccoli.

“…Salinity is one of the worst abiotic stresses that threaten agricultural production in the 21 st century, and its adverse effects are expected to increase due to the climate change in recent years, especially in semi-arid regions Souri, 2018;Souana et al, 2020).…”

The cultivation of soursop has increased in recent years due to the advance of agribusiness and due to its use by the pharmaceutical industry. As a source of vitamin C, calcium, carbohydrates and antioxidant substances, soursop helps to protect the human body against oxidative stress, acting in the prevention of a series of chronic degenerative disorders. In this context, the objective of present study was to evaluate the effects of foliar sprays with salicylic acid to mitigate the effects of salt stress on the morphophysiology of soursop. The study was conducted in a greenhouse, in a randomized block design and a 5 × 4 factorial arrangement, with five levels of electrical conductivity of irrigation water - ECw (0.8-control; 1.6; 2.4; 3.2 and 4.0 dS m-1) and four concentrations of salicylic acid - SA (0; 1.2; 2.4 and 3.6 mM), with three replicates. Foliar application of SA at concentrations between 1.2 and 1.6 mM mitigated the effects of salt stress on stomatal conductance, CO2 assimilation rate, transpiration and instantaneous carboxylation efficiency of soursop at 480 days after transplanting. Spraying with SA at concentrations between 1.3 and 1.6 mM induced acclimatization to salt stress in soursop plants, since the percentage of intercellular electrolyte leakage was reduced and the growth was favored by the application of SA, even when exposed to salinity. Irrigation with ECw above 0.8 dS m-1 reduced the relative water content in the leaves of soursop cv. Morada Nova.
