“…In the future, new mutants, especially of the flavonoid metabolism, need to be obtained to investigate the mutualistic interaction in more depth. It is possible that plant-growth promoting microorganisms can be valuable tools for crop improvement [ 7 , 50 ], as they promote the plant growth and help the plant to cope with abiotic and biotic stress factors.…”

Piriformospora indica is a root-colonizing fungus, which interacts with a variety of plants including Arabidopsis thaliana. This interaction has been considered as mutualistic leading to growth promotion of the host. So far, only indolic glucosinolates and phytohormones have been identified as key players. In a comprehensive non-targeted metabolite profiling study, we analyzed Arabidopsis thaliana’s roots, root exudates, and leaves of inoculated and non-inoculated plants by ultra performance liquid chromatography/electrospray ionization quadrupole-time-of-flight mass spectrometry (UPLC/(ESI)-QTOFMS) and gas chromatography/electron ionization quadrupole mass spectrometry (GC/EI-QMS), and identified further biomarkers. Among them, the concentration of nucleosides, dipeptides, oligolignols, and glucosinolate degradation products was affected in the exudates. In the root profiles, nearly all metabolite levels increased upon co-cultivation, like carbohydrates, organic acids, amino acids, glucosinolates, oligolignols, and flavonoids. In the leaf profiles, we detected by far less significant changes. We only observed an increased concentration of organic acids, carbohydrates, ascorbate, glucosinolates and hydroxycinnamic acids, and a decreased concentration of nitrogen-rich amino acids in inoculated plants. These findings contribute to the understanding of symbiotic interactions between plant roots and fungi of the order of Sebacinales and are a valid source for follow-up mechanistic studies, because these symbioses are particular and clearly different from interactions of roots with mycorrhizal fungi or dark septate endophytes

“…Moreover, P. indica root endophyte has been credibly evidenced to minimize the use of chemical fertilizers, control crop yield, and also to provide increased resistance and tolerance in plants against biotic and abiotic stresses ( Unnikumar et al, 2013 ). In our recent effort, P. indica -mediated improvements in the biomass, seed germination, plant growth and development and crop productivity under favorable environmental conditions were highlighted, and P. indica was argued as a powerful tool for crop improvement ( Ansari et al, 2014 ).…”

Piriformospora indica: Potential and Significance in Plant Stress Tolerance

Owing to its exceptional ability to efficiently promote plant growth, protection and stress tolerance, a mycorrhiza like endophytic Agaricomycetes fungus Piriformospora indica has received a great attention over the last few decades. P. indica is an axenically cultiviable fungus which exhibits its versatility for colonizing/hosting a broad range of plant species through directly manipulating plant hormone-signaling pathway during the course of mutualism. P. indica-root colonization leads to a better plant performance in all respect, including enhanced root proliferation by indole-3-acetic acid production which in turn results into better nutrient-acquisition and subsequently to improved crop growth and productivity. Additionally, P. indica can induce both local and systemic resistance to fungal and viral plant diseases through signal transduction. P. indica-mediated stimulation in antioxidant defense system components and expressing stress-related genes can confer crop/plant stress tolerance. Therefore, P. indica can biotize micropropagated plantlets and also help these plants to overcome transplantation shock. Nevertheless, it can also be involved in a more complex symbiotic relationship, such as tripartite symbiosis and can enhance population dynamic of plant growth promoting rhizobacteria. In brief, P. indica can be utilized as a plant promoter, bio-fertilizer, bioprotector, bioregulator, and biotization agent. The outcome of the recent literature appraised herein will help us to understand the physiological and molecular bases of mechanisms underlying P. indica-crop plant mutual relationship. Together, the discussion will be functional to comprehend the usefulness of crop plant-P. indica association in both achieving new insights into crop protection/improvement as well as in sustainable agriculture production.

“…Of these, Piriformospora indica , a plant‐root‐colonizing basidiomycete fungus, is analogous to arbuscular mycorrhizal fungi (AMF) in many morphological, functional and growth promotional aspects (Rai & Varma, ). Recently, P. indica has been confirmed to be a potent new candidate symbiont for a broad spectrum of mono‐ and dicot plants, conveying several benefits to the host plants including growth promotion along with better resistance to various biotic and abiotic stresses (Ansari, Gill, & Tuteja, ; Franken, ; Oelmüller et al., ; Trivedi et al, ,b; Varma et al., ). P. indica inoculation was found to improve tremendously the growth and biomass of diverse hosts including Oryza sativa, Triticum sativum, Zea mays, Setaria italica, Sorghum vulgare (Achatz et al., ; Baltruschat et al., ; Varma, Rai, & Sahay, ; Varma, Verma, Sudah, & Franken, ), Arabidopsis thaliana (Peškan‐Berghöfer et al., ; Shahollari, Varma, & Oelmüller, ; Sherameti et al., ), Hordeum vulgare (Achatz et al., ; Baltruschat et al., ; Waller et al., , ), Nicotiana attenuata (Barazani, Dahl, & Baldwin, ), Brassica chinensis (Sun et al., ) and Lycopersicon esculentum (Sarma et al., ; Trivedi et al, ,b).…”

This study aimed to evaluate the ability of Piriformospora indica to colonize the root of Chenopodium quinoa and to verify whether this endosymbiont can improve the growth, performance and drought resistance of this species. The study delivered, for the first time, evidence for successful colonization of P. indica in quinoa. Hence, pot experiment was conducted in the greenhouse, where inoculated and non-inoculated plants were subjected to ample (40%-50% WHC) and deficit (15%-20%WHC) irrigation treatments. Drought adversely influenced the plant growth, leading to decline the total plant biomass by 74%. This was linked to an impaired photosynthetic activity (caused by lower g s and C i /C a ratio; stomatal limitation of photosynthesis) and a higher risk of ROS production (enhanced ETR/A gross ratio). P. indica colonization improved quinoa plant growth, with total biomass increased by 8% (controls) and 76% (drought-stressed plants), confirming the growth-promoting activity of P. indica. Fungal colonization seems to diminish drought-induced growth hindrance, likely, through an improved water balance, reflected by the higher leaf w w and g s .Additionally, stomatal limitation of photosynthesis was alleviated (indicated by enhanced C i /C a ratio and A net ), so that the threat of oxidative stress was minimized (decreased ETR/A gross ). These results infer that symbiosis with P. indica could negate some of the detrimental effects of drought on quinoa growth, a highly desired feature, in particular at low water availability.
