“…This resulted in an improvement in the biomass of the strawberry plantlets and a noticeable growth promotion effect. These findings are consistent with a previous study that showed that P. indica can significantly increase the biomass of longan [30]. The plant height, stem diameter, leaf area, petiole length, and root length of strawberries in PF were significantly greater than those in F. This improved the promotion effect of P. indica on strawberry growth under Fof stress.…”

Strawberry Fusarium wilt, mainly caused by Fusarium oxysoporum f. sp. Fragariae (Fof), seriously threatens the yield and quality of strawberry. Piriformospora indica is an endophytic fungus that can colonise the roots of a wide range of plants, promoting plant growth and enhancing plant resistance. Against this background, the positive effects of P. indica on the growth of the daughter plants of ‘Benihoppe’ strawberry (Fragaria × ananassa Duch.) under Fof stress were investigated in this study. The study began by examining the inhibitory effect of P. indica on Fof growth through dual culture on agar plates. Subsequently, a symbiotic system between P. indica and strawberry plantlets was established, and the impact of P. indica on Fusarium wilt resistance and related physiological and biochemical indexes of the plantlets were evaluated. The results indicate that fungus colonization with P. indica significantly enhances the growth indices of strawberries, including plant height, petiole length, petiole diameter, and leaf area. Additionally, the activities of superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) in the leaves of P. indica were increased, and the content of malondialdehyde (MDA) was decreased compared to those without colonization. Under the stress from Fof, the growth indexes of plant height, stem diameter, leaf area, petiole diameter, and root length of strawberry plants colonization with P. indica were significantly higher than those without colonization and the symptoms of wilting were relatively mild. The activities of SOD, POD, and CAT in roots and leaves of plants colonized with P. indica were significantly increased compared to those without colonization. Furthermore, the content of MDA in roots was decreased. These results suggested that P. indica could increase resistance to Fusarium wilt in strawberry by increasing the activity of antioxidant enzymes and reducing the content of MDA.

“…It seemed that P. indica could maintain the process of photosynthesis under Ni stress by inducing the defense system of the antioxidant enzymes, which could subside the Ni-induced oxidative stress. Such similar results have already been reported for tomatoes (Solanum Lycopersicum L.) (Ghorbani et al, 2018) and Dimocarpus longan seedlings (Cheng et al, 2022). There are also some antioxidant enzymes in plants, and it is expected that the P. indica inoculation can stimulate some of them, though the CAT activity decreased.…”

As an essential nutrient for plant growth, nickel's (Ni) requirement is very low, and its augmented level causes environmental pollution and toxicity. Being a root endophytic fungus, Piriformospora indica (P. indica) can be beneficial to many plants under stress and non-stress conditions, particularly in terms of their improved growth performance. P. indica, as evidenced, enhances tolerance and resistance in most plants once they experience a range of stresses caused by biotic and abiotic factors, e.g., diseases and heavy metals. Against this background, the positive effects of P. indica on the tomato plants under Ni-induced stress (300, 600, and 900 mg L−1) were analyzed in three experiments at labs, at greenhouses, and via aeroponics in this study. The growth traits of the tomato plants, such as root length (RL) and root dry weight (RDW), were accordingly found to be positively boosted in the cases treated with P. indica compared to the non-treated ones. Treating with P. indica also thwarted the negative effects of Ni on some biochemical traits, including anthocyanin (Anth), proline (Pro), catalase (CAT), and glutathione peroxidase (GPx), while significantly minimizing the adverse impacts of this heavy metal at different levels on hydrogen peroxide (H2O2). Despite this, the Ni-stressed plants indicated much better traits in the presence of this fungus, compared with the non-treated ones, in most of the cases measured. Moreover, the photosynthetic pigments, i.e., chlorophyll a and b (Chl a & b) and carotenoid content (Carrot), were significantly higher in the tomato plants treated with P. indica under high Ni-induced stress as compared with the non-treated ones under non-Ni conditions, in which these pigments were low. The pro-production was further observed all through the P. indica inoculation, which could aid the treated plants in becoming Ni-stress-tolerant. Finally, the current study contributed to a better understanding of how to use the P. indica symbiosis to induce heavy metal tolerance in tomato plants, such as Ni, to meet the goals of sustainable agriculture.

“…In addition, fungi can also form mycorrhizae in symbiosis with plant roots, promoting the growth of both aboveground and underground parts, providing additional moisture and nutrients, and enhancing plant photosynthetic capacity, which is of great significance to agricultural production and the balance of plant ecosystems [ 27 ]. Currently, P. indica is widely discussed as a beneficial fungus in plants such as strawberry [ 7 ], longan [ 10 ], and rice [ 11 ]. Studies have shown that the growth parameters of barley [ 28 ], king grass [ 29 ], ryegrass [ 30 ], tobacco [ 31 ], African chrysanthemum [ 32 ], and maize [ 33 ] colonized by P. indica are higher than those of non-inoculated controls.…”

“…Piriformospora indica can enhance root development by promoting plant hormone secretion. Research has revealed that colonization by P. indica can increase POD enzyme activity and IAA content in the Dimocarpus longan root system, thereby enhancing the absorption capacity of longan roots for nutrients and promoting the growth of longan cuttings [ 10 ]. In rice, colonization by P. indica can promote aboveground growth and induce the expression of genes related to growth, increase chlorophyll content, and enhance root vitality.…”

Numerous studies have shown that the endophytic fungus Piriformospora indica has a broad range of promoting effects on root development and plant growth in host plants. However, there are currently no reports on the application of this fungus on Cerasus humilis. This study first compared the colonization ability of P. indica on 11 C. humilis varieties and found that the colonization rate of this fungus on these varieties ranged from 90% to 100%, with the colonization rate of the varieties ‘09-01’ and ‘Nongda 7’ being as high as 100%. Subsequently, the effect of P. indica on root development and plant growth of C. humilis was investigated using cuttings of ‘09-01’ and ‘Nongda 7’ as materials. P. indica colonization was found to increase the biomass of ‘09-01’ and ‘Nongda 7’ plants; root activity, POD enzymes, and chlorophyll content were also significantly increased. In addition, indole-3-acetic acid (IAA) content in the roots of C. humilis plants increased after colonization, while jasmonic acid (JA) and 1-aminocyclopropane-1-car- boxylic acid (ACC) content decreased. In conclusion, it has been demonstrated that P. indica can promote the growth of C. humilis plants by accelerating biomass accumulation, promoting rooting, and enhancing the production of photosynthetic pigments, as well as regulating hormone synthesis.
