“…Salinity stress affects the growth and metabolism of plants and causes a reduction in most growth indices. The decline in the growth parameters as a result of salinity stress was recorded in different investigations [ 50 , 51 , 52 ]. Our findings are in accordance with those documented by Zhang et al [ 53 ], who found that plant height, root length, shoot fresh and dry weight, and root fresh and dry weight were markedly decreased as a result of salt stress.…”

Symbiotic plant-fungi interaction is a promising approach to alleviate salt stress in plants. Moreover, endophytic fungi are well known to promote the growth of various crop plants. Herein, seven fungal endophytes were screened for salt tolerance; the results revealed that Aspergillus ochraceus showed a great potentiality in terms of salt tolerance, up to 200 g L−1. The indole acetic acid (IAA) production antioxidant capacity and antifungal activity of A. ochraceus were evaluated, in vitro, under two levels of seawater stress, 15 and 30% (v/v; seawater/distilled water). The results illustrated that A. ochraceus could produce about 146 and 176 µg mL−1 IAA in 15 and 30% seawater, respectively. The yield of IAA by A. ochraceus at 30% seawater was significantly higher at all tryptophan concentrations, as compared with that at 15% seawater. Moreover, the antioxidant activity of ethyl acetate extract of A. ochraceus (1000 µg mL−1) at 15 and 30% seawater was 95.83 ± 1.25 and 98.33 ± 0.57%, respectively. Crude extracts of A. ochraceus obtained at 15 and 30% seawater exhibited significant antifungal activity against F. oxysporum, compared to distilled water. The irrigation of barley plants with seawater (15 and 30%) caused notable declines in most morphological indices, pigments, sugars, proteins, and yield characteristics, while increasing the contents of proline, malondialdehyde, and hydrogen peroxide and the activities of antioxidant enzymes. On the other hand, the application of A. ochraceus mitigated the harmful effects of seawater on the growth and physiology of barley plants. Therefore, this study suggests that the endophytic fungus A. ochraceus MT089958 could be applied as a strategy for mitigating the stress imposed by seawater irrigation in barley plants and, therefore, improving crop growth and productivity.

Coating seeds with bio-control agents is a potentially effective approach to reduce the usage of pesticides and fertilizers applied and protect the natural environment. This study evaluated the effect of seed coating with Meyerozyma guilliermondii, strain INAT (MT731365), on seed germination, plant growth and photosynthesis, and plant resistance against Fusarium culmorum, in durum wheat under controlled conditions. Compared to control plants, seed coating with M. guilliermondii promoted the wheat growth (shoot and roots length and biomass), and photosynthesis and transpiration traits (chlorophyll, ɸPSII, rates of photosynthesis and transpiration, etc.) together with higher nitrogen balance index (NBI) and lower flavonols and anthocyanins. At 21 days post infection with Fusarium, M. guilliermondii was found to reduce the disease incidence and the severity, with reduction rates reaching up to 31.2% and 30.4%, respectively, as well as to alleviate the disease damaging impact on photosynthesis and plant growth. This was associated with lower ABA, flavonols and anthocyanins, compared to infected control. A pivotal function of M. guilliermondii as an antagonist of F. culmorum and a growth promoter is discussed.

“…Salinity greatly affects germination and vigor of the plant species, thus reduces the growth, development and yield of agricultural crops [20,31]. The presence of higher amounts of salts in soil may cause various metabolic and physiological disturbances [34,44], which can lead to low yield and quality of grains.…”

“…Moreover, it affects plant's survival percentage, germination of seeds, and various morphological characteristics [41]. Nutritional disorders, ions toxicity, and nutrients imbalance in cytosol have been noticed in plants due to transport and dispersion of high salt contents [2,20]. Besides, it leads to oxidative stress at cellular and subcellular level that generates ROS (reactive oxygen species).…”

Background In the list of abiotic stresses, salt stress is a main growth retarding factor which affects 7% of rain-fed while 30% worldwide irrigated agriculture. However, various strategies are assumed to manage this problem, but the use of endophytes is cheap and eco-friendly. The goal of this study was to evaluate the behavior of endophytic Aspergillus awamori (EWF) in creating salt tolerance in mung bean in terms of its seedling growth, biochemical indices, antioxidant enzymes, endogenous IAA, and ionic status of the plant. Results The results revealed that the 150 mM of NaCl reduced seedling growth (seedlings’ weight and length; leaves number), chlorophyll contents, and IAA. On the other hand, proline, polyphenols, flavonoids, tannin, lipid peroxidation, catalase, and ascorbate peroxidase were increased. Inoculation of EWF had promoted the mung bean growth under all tested conditions. EWF enhanced the biomass and IAA contents of the mung bean plants under salt stress. Moreover, EWF-associated mung bean seedlings exhibited low accumulation of stress markers, and Cl, Na, Na/K, and Ca/K ratio, whereas higher concentrations of Ca, Mg, K, N, and P in mung bean seedlings. Conclusion The results provided a sustainable approach in using endophytic EWF under salt stress, thus concluded that this fungus can be very handy in mung bean as well as other important crop production in saline areas.
