“…The association of mung bean with A. awamori, on the other hand, regulated the flavonoid contents in mung bean plants during salt stress. Various reports confirmed an increased flavonoids contents in different plant species under stress [21,44]. In fact, plant activates different antioxidant systems, such as flavonoids and phenolics, to defend themselves against the ROS, produced during stresses.…”

“…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].…”

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.

“…Proline and phenolics are accumulated in higher plants during abiotic stresses and function as osmolytes, protein and membrane stabilizers, buffer of cellular redox reactions and as ROS foragers (Khushdil et al 2019;Muhammad et al 2019;Nusrat et al 2019). Moreover, proline also helps in balancing the ratio of NADP + /NADPH necessary for cellular metabolism, maintenance of cellular-acidosis and protein-compatible-hydrotrope.…”

Plants can be severely affected by heat stress due to rapid environmental changes. Use of endophytic fungi is a new tool to protect crops from the environmental stresses. Here we claim a potent endophyte isolated from Sonchus asper L. The aim was to explore the stress adaptive mechanism of sunflower and soybean mediated by Aspergillus niger (SonchL-7) under high temperature. Inoculation with A. niger boosted plant height, biomass and chlorophyl contents, while significantly curtailed the concentration of lipid peroxidation and reactive oxygen species (ROS) under thermal stress at 40°C. Moreover, the ROS-scavenging activities, like ascorbic acid oxidase (AAO), catalase (CAT), glutathione reductase (GR), superoxide dismutase (SOD) and peroxidase (POD) were augmented. Also, proline and phenolics were enhanced in the tested crops, while ABA concentration was significantly reduced. These positive results suggested that A. niger can be used as a heat-stress ameliorative tool for crops in the future.

“…For example, Cochliobolus can be used as a biochemical modulator to alleviate salinity stress in okra plants [34,35]. Chloromonilinic acids C and D extracted from Cochliobolus australiensis showed toxic effect to buffelgrass in a seedling elongation bioassay, with significantly delayed germination and dramatically reduced radicle growth, especially at a concentration of 5 × 10 -3 M [36].…”

Cochliobolus is a Dematiaceous fungi that belong to family: Pleosporaceae. It is known as worldwide pathogen of mostly grasses that caused devastating disease epidemics of important economic food crops as wheat, rice, and maize. Many Cochliobolus species have their asexual states, and consequently synonyms, in either Bipolaris or Curvularia. In this review, highlights were presented on Cochliobolus species as models of fungi rich in therapeutic agents that can be employed in different applications. Moreover, describing the importance and potentials of this fungus in order to encourage for further studies to search, isolate, and purify already known metabolites. Also, screen for, and discover novel metabolites produced by those potent fungi in order to be involved in additional applications.
