“…The effect of SA addition on antioxidant enzymes was observed in Vigna radiata plants subjected to Al (Ali 2017) and in fennel genotypes under drought conditions (Askari and Ehsanzadeh 2015). Several plant species such as soybean (Liu et al 2017), rice (Pandey et al 2013), coffee (Muñoz-Sanchez et al 2013), and Panax notoginseng (Dai et al 2019) have shown protective effect of exogenous SA on Al toxicity. Although most studies have indicated that SA induced antioxidative enzyme activity under stress, some researches have reported CAT activity decrease under such an unfavorable condition (Krantev et al 2008;Guo et al 2013;Pandey et al 2013), as observed in T. vesiculosum (Fig.…”

Aluminum (Al) toxicity is one of the main aspects restricting the development of fabaceous plants grown in soils with spontaneous vegetation prevalence in temperate climate zones. Salicylic acid (SA) minimizes the effects of stress on plants. Therefore, the aim of the current study was to evaluate the ability of SA seed priming to mitigate the effects of Al on seed germination and seedling performance in two Trifolium species. Trifolium vesiculosum (annual) and Trifolium repens (perennial) seeds were primed in solution added, or not, with SA (25 μM) and placed on germination paper moistened with aluminum sulfate (Al 2 (SO 4) 3) solutions at three different doses: 0 mM (control), 0.25 mM (moderate dose), and 1.25 mM (high dose). Seed priming with SA has mitigated the global toxicity effects of Al on T. vesiculosum and T. repens seedlings. Inferior damages were observed in T. vesiculosum root length and dry mass and in T. repens shoot dry mass, after SA pretreatment. T. vesiculosum seed priming with SA in the presence of Al has significantly reduced the osmotic potential of seedling sap. Salicylic acid (SA) has also enabled increased antioxidant activity of enzymes such as superoxide dismutase (SOD) in the two investigated plant species and ascorbate peroxidase (APX) in T. repens. In addition to the increased antioxidant activity, SA-primed seeds reduced the malondialdehyde content in T. vesiculosum seedlings exposed to Al. Overall, seed priming with SA mitigates oxidative effects of Al and improves T. vesiculosum and T. repens seedling performance in the presence of this element.

“…This increase in NPQ can prevent damage caused by stress due to excess energy in the photosynthetic apparatus. In this sense, the increase in NPQ induced by the feeding of B. tabaci can reduce the number of electrons flowing through photosynthesis, that is, reducing the stress due to excess light in photosystem II [48,[50][51][52].…”

Infestation by Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) causes damage to tomatoes with production losses of up to 100%, affecting the physiological and biochemical aspects of host plants. The objective of this study was to analyze the influence of infestation of cryptic species of B. tabaci MED and MEAM1 on the physiological and biochemical aspects of tomato. Tomato plants ‘Santa Adélia Super’ infested with B. tabaci (MED and MEAM1), and non-infested plants were evaluated for differences in gas exchange, chlorophyll - a fluorescence of photosystem II (PSII), and biochemical factors (total phenols, total flavonoids, superoxide dismutase—SOD, peroxidase—POD, and polyphenol oxidase—PPO). Plants infested with B. tabaci MED showed low rates of CO2 assimilation and stomatal conductance of 55% and 52%, respectively. The instantaneous carboxylation efficiency was reduced by 40% in MED and by 60% in MEAM1 compared to the control. Regarding biochemical aspects, plants infested by MED cryptic species showed high activity of POD and PPO enzymes and total phenol content during the second and third instars when compared to control plants. Our results indicate that B. tabaci MED infestation in tomato plants had a greater influence than B. tabaci MEAM1 infestation on physiological parameters (CO2 assimilation rate (A), stomatal conductance (gs), and apparent carboxylation efficiency (A/Ci)) and caused increased activity of POD and PPO enzymes, indicating plant resistance to attack. In contrast, B. tabaci MEAM1 caused a reduction in POD enzyme activity, favoring offspring performance.

“…Al 3+ toxicity is one of the major factors constraining plant growth and crop production worldwide [5]. In acid soil (pH < 5.5), aluminum is solubilized into the toxic form of Al 3+ ions, which trigger signal disruption (e.g., ROS overproduction), resulting in oxidative damage and physiological changes (e.g., root growth inhibition), eventually reducing crop yields [41][42][43]. Melatonin, an indole compound, has been shown to exert multiple effects in plants, such as mediating root elongation and photosynthesis, enhancing the plant tolerance under biotic and abiotic stresses [3,30,44].…”

This study was conducted to evaluate the Al3+ tolerance of sixteen camelina genotypes and to use melatonin or nano-selenium to alleviate Al3+-induced stress. A Petri dish study indicated seedling root length was suitable for describing the dose–response of seedling growth with increased Al3+ concentrations. Based on GR50 (Al3+ concentration causing a 50% reduction in the seedling root length), CamK6 (232.0 mg L−1) and CamK2 (97.0 mg L−1) were the most Al3+-tolerant and -sensitive genotypes, respectively. Under Al3+ stress, CamK6 and CamK2 treated by melatonin (50 μM) or nano-Se (0.4 mg L−1) showed a similar plant height and seed yield plant−1 (CamK6: 123.6 ± 9.8 cm and 0.562 ± 0.62 g; CamK2: 109.2 ± 8.7 cm and 0.49 ± 0.5 g) as the controls (CamK6: 121.1 ± 10.2 cm and 0.554 ± 0.4 g; CamK2: 110.0 ± 9.8 cm and 0.5 ± 0.4 g), and the values were greater than for the Al3+-treated plants (CamK6: 96.4 ± 9.2 cm and 0.48 ± 0.34 g; CamK2: 97.3 ± 8.1 cm and 0.42 ± 0.31 g). The results showed that melatonin or nano-Se through modulating biochemical reactions (e.g., antioxidant enzyme) can alleviate Al3+-induced growth inhibition in camelina. This study suggested melatonin or nano-Se can alleviate Al3+-induced growth inhibition by maintaining seed yield and improving oil quality in camelina.
