“…The response is not a simple additive of every single stress, but a synergistic result of the combination [ 15 ]. In addition to these studies, soybean crop under water deficit stress is also evaluated recently in combination with UV-B radiation [ 16 ], cadmium [ 17 ], and heavy metal [ 18 ].…”

The aim was to evaluate the interactive effects on biochemistry and physiology of soybean plants exposed to simultaneous xenobiotic and water deficit stresses, and the possible attenuation of plant damage by an antioxidant agent. Soybean plants were submitted to eight different soil water potentials, in two experiments (first experiment: −0.96, −0.38, −0.07, −0.02 MPa, and second experiment: −3.09, −1.38, −0.69, −0.14 MPa), xenobiotic, and antioxidant agent applications. Was observed a reduction in water status, gas exchange, photosynthetic pigments, photosystem II quantum yield, and increased leaf temperature in plants under low water availability. Water deficit also induced oxidative stress by the increased production of reactive oxygen species, cellular and molecular damage, and induction of the antioxidant defense metabolism, reduction of gas exchange, water status, and photosynthetic efficiency. The xenobiotic application also caused changes, with deleterious effects more pronounced in low soil water availability, mainly the reactive oxygen species production, consequently the antioxidant activity, and the oxidative damages. This indicates different responses to the combination of stresses. Antioxidant enzyme activity was reduced by the application of the antioxidant agent. Principal Component Analysis showed a relation with the antioxidant agent and reactive oxygen species, which is probably due to signaling function, and with defense antioxidant system, mainly glutathione, represented by thiols.

“…A few horizontally transmitted Class 3 FE are also reported to reduce insect attack of plants (Vega, 2008;Vidal and Jaber, 2015). The action of endophytes in plants may often be due to the synergy with other co-existing endophytes, fungi, or bacteria as was demonstrated by Bilal et al (2020). They showed that the two EF, Paecilomyces formosus and Pencillium funiculosum acted synergistically to impart tolerance to drought, high temperature, and heavy metals (Bilal et al, 2020).…”

Fungal Endophyte-Mediated Crop Improvement: The Way Ahead

Endophytes are non-disease causing microbes (bacteria and fungi) surviving in living tissues of plants. Their intimate association and possible coevolution with their plant partners have resulted in them contributing to an array of plant growth benefits ranging from enhanced growth and biomass accumulation, tolerance to abiotic and biotic stresses and in nutrient acquisition. The last couple of decades have witnessed a burgeoning literature on the role of endophytes (Class 3 type) in regulating plant growth and development and their adaptation to abiotic and biotic stresses. Though the underlying mechanisms of plant-endophyte interactions are far from clear, several studies have raised the hope of their potential application in agriculture, especially in mitigating abiotic and biotic stresses. The use of endophytes is envisaged as a route to reduce the production cost and burden on the environment by lessening the dependence on breeding for crop improvement and agrochemicals. Unfortunately, save a few well documented examples of their use, a little of these insights has been translated into actual agricultural applications. Here, we reflect on this paucity and elaborate on some of the important bottlenecks that might stand in way of fully realizing the potential that endophytes hold for crop improvement. We stress the need to study various facets of the endophyte-plant association for their gainful application in agriculture.

“…The use of endophytic fungi for environmental applications such as growth promotion, relief of abiotic stress, biocontrol of pest and plant pathogens and bio/phytoremediation has gained important attention in recent years due to the concern about global climate change and contamination in soils and natural sources that increases stress in crops, limiting and reducing the production [ 8 , 9 , 10 , 11 ]. Furthermore, basic and applied research has been conducted to develop processes, methodologies and technologies that resulted in a considerable number of patents with new proposals to overcome some of these challenges.…”

Patents on Endophytic Fungi for Agriculture and Bio- and Phytoremediation Applications

Plant endophytic fungi spend all or part of their lives inside host tissues without causing disease symptoms. They can colonize the plant to protect against predators, pathogens and abiotic stresses generated by drought, salinity, high concentrations of heavy metals, UV radiation and temperature fluctuations. They can also promote plant growth through the biosynthesis of phytohormones and nutrient acquisition. In recent years, the study of endophytic fungi for biological control of plant diseases and pests has been intensified to try to reduce the ecological and public health impacts due the use of chemicals and the emergence of fungicide resistance. In this review, we examine 185 patents related to endophytic fungi (from January 1988 to December 2019) and discuss their applicability for abiotic stress tolerance and growth promotion of plants, as agents for biocontrol of herbivores and plant pathogens and bio- and phytoremediation applications.
