“…The decrease in O 2 •− concentrations and the increase in H 2 O 2 concentrations in our study showed that S. indica initiated SOD to scavenge O 2 •− , thus inducing a burst in H 2 O 2 . Further analysis showed that inoculation of S. indica significantly reduced the H 2 O 2 and O 2 •− concentration of white clover under NW conditions, and only reduced the H 2 O 2 concentration under WS conditions, with no significant effect on O 2 •− under WS conditions, which is consistent with the results of previous studies on rice ( Swetha and Padmavathi, 2019 ). This may be due to the fact that S. indica increased antioxidant enzyme activities and antioxidant concentrations in the plants, which synergistically scavenged excess ROS and thus reduced the oxidative damage to cells by ROS.…”

“…This fungus improves plant growth, promotes nutrient absorption, and enhances stress resistance of plants ( Aslam et al, 2019 ). It has been shown that inoculation of S. indica on Solanum melongena plants significantly increased peroxidase (POD) and catalase (CAT) activities in roots under WS ( Swetha and Padmavathi, 2019 ). Serendipita indica also increased CAT and GR activities but reduced GSH content of rice under WS, along with no change in superoxide dismutase (SOD) and APX activities and reduced ASC content ( Tsai et al, 2020 ).…”

Ascorbate-glutathione cycle is an important pathway for plants to scavenge reactive oxygen species (ROS) under environmental stress conditions. The objective of this study was to investigate the effects of the endophytic fungus Serendipita indica on biomass, chlorophyll concent, ROS levels, antioxidant enzyme activities, and ascorbate-glutathione cycle in white clover under ample water and water stress conditions. The results showed that 46 days of soil water stress distinctly promoted root colonization by S. indica. Under water stress, S. indica inoculation significantly promoted shoot and root biomass, total chlorophyll content, and activities of superoxide dismutases (SOD; e.g., Fe-SOD and Cu/Zn-SOD) and peroxidase in roots, coupled with a decrease in malondialdehyde content in roots. In the ascorbate-glutathione cycle of roots, S. indica also significantly increased the activity of ascorbate peroxidase and glutathione reductase activities in water-stressed white clover, along with the increase in reduced ascorbic acid and reduced/oxidized glutathione contents, thus accelerating the ascorbate-glutathione cycle in inoculated plants to scavenge more ROS (e.g., hydrogen peroxide). As a result, S. indica enhanced the tolerance of white clover in response to water stress by enhancing antioxidant enzyme activities and accelerating the ascorbate-glutathione cycle.

Plant growth promotion through versatile microorganisms inhabiting the rhizospheric region of the soil has emerged as a sustainable approach in improving the crop productivity and crop health management. The present study reports the isolation and characterization of halotolerant as well as drought tolerant isolates that possess exceptional plant growth promotional attributes. Out of 32 isolates obtained, 13 isolates exhibited excellent plant growth promotional attributes such as phosphate solubilization, phytohormone production, siderophore production etc. Among 13 isolates tested for stress tolerance studies, two isolates Mulberry -1 and Ragi-7 were able to tolerate both drought and saline stresses and were further identified as Bacillus licheniformis and Bacillus wudalianchiensis based on biochemical and molecular techniques. Antibiosis activity of both the isolates tested against two important plant pathogens Fusarium oxysporum and Phomopsis vexans was found to be positive. Bacillus licheniformis and Bacillus wudalianchiensis were further tested for their efficacy to solubilize five different inorganic phosphate sources. The amount of phosphate liberated was found to be highest (3562 mgml-1 and 1894 mgml-1) with diammonium phosphate followed by single super phosphate and tricalcium phosphate with respect to Bacillus licheniformis and Bacillus wudalianchiensis. Zea mays L. seeds treated with the culture filtrate of both the isolates were cultivated on Murashige-Skoog medium under In-vitro conditions. Bacillus wudalianchiensis was found to be better compared to Bacillus licheniformis with respect to plant growth promotional aspects as they were able to increase the root and shoot length of Zea mays L. under In-vitro conditions. Application of the multifaceted capabilities of unexplored halotolerant strain of Bacillus wudalianchiensis could open up a new avenue in plant biotechnology.

“…One of these beneficial microorganisms is S. indica , which can colonize the roots of a wide range of plants and increase their drought resistance by affecting the physiological characteristics of the host plant [ 87 ]. Various studies have shown the effect of S. indica in reducing the adverse effects of drought on the following plants: Brassica rapa , Hordeum vulgare [ 25 ], Solanum melongena L. [ 88 ], Medicago, rice, arabidopsis, and maize [ 27 ].…”

“…In summary, the positive role of S. indica in decreasing drought effects in plants can be divided into four main groups: (1) improving water and nutrient uptake [ 55 , 88 ], (2) increasing chlorophyll synthesis, (3) accumulation of high proline content, and (4) protection against ROS by overproduction of antioxidant enzymes [ 88 ]. The role of S. indica in increasing the growth of host plants and helping to better absorb nutrients such as N and P as well as the effect on better water uptake by plants, is known; scientists attribute the positive effect of S. indica to improving plant yield under drought conditions to the origin of this fungus, which is from arid areas [ 55 ].…”

Plant stress is one of the biggest threats to crops, causing irreparable damage to farmers’ incomes; Therefore, finding suitable, affordable, and practical solutions will help the agricultural economy and prevent the loss of millions of tons of agricultural products. Scientists have taken significant steps toward improving farm productivity in the last few decades by discovering how beneficial soil microorganisms enhance plant resistance to environmental stresses. Among these microorganisms is Serendipita indica, which the benefits of coexisting this fungus with plant roots have been extensively explored in recent years. By investigating fungus specification and its effects on plants’ morphological, physiological, and molecular traits, the present study seeks to understand how Serendipita indica affects plant resistance to salinity and drought conditions. Furthermore, this study attempts to identify the unknown mechanisms of action of the coexistence of Serendipita indica with plants in the face of stress using information from previous studies. Thus, it provides a way for future research to assess the impact of this fungus on tackling environmental stresses and enhancing agricultural productivity.
