“…On the perspective of P. indica colonization role in crop plants, P. indica -mediated improvements in the growth and biomass have been reported in a number of crop plants including Oryza sativa, Saccharum officinarum, Abrus precatorius, Zea mays, Phaseolus vulgaris , and Tridax procumbans ( Prasad, 2008 ; Varma et al, 2012a , b , 2013 , 2014 ). P. indica can produce auxin (IAA) which in turn can promote plant root growth ( Sirrenberg et al, 2007 ).…”

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.

“…This fungus has growth promoting effects mimicking those of arbuscular mycorrhizal fungi Chadha et al, 2014) and increases biomass and yield of many plant species (Malla et al, 2004;Varma et al, 2014). It colonizes a wide range of plants including gymnosperms, angiosperms and orchids (Ye et al, 2014) and improves growth through increased nutrient uptake (N and P) of the host plants (Sherameti et al, 2005;Yadav et al, 2010).…”

“…P. indica -induced seed germination and stimulation was earlier observed in orchids (Blechert et al 1999 ) and it also helps to promote seed yield and quality of Brassica napus (Zen-zhuSu et al , 2017 ). Varma et al ( 2014 ) reported that P. indica culture filtrate promotes plant growth and seed germination in Helianthus annuus and Phaseolus vulgaris .…”

“…Along with the application of P. indica as a plant promoter in a broad range of plants, it is also used as biofertiliser, bioregulator, bio-herbicide, immunomodulator, phytoremediator, biocontrol against insects and pathogens, biotic and abiotic stress tolerance antioxidative agent and biohardening agent (Varma et al 2014 ). P. indica is capable as a biohardening agent in different in vitro plants tested (Sahay and Varma 1999 ).…”

“…Although the fungus was isolated from hot conditions, P. indica has the ability to withstand both the extreme cold and hot conditions. The cold tolerance was evidenced by the experiment in the cold deserts of Leh-Ladakh (Varma et al 2014 ). Recently, P. indica is documented to reduce the effects of heavy metal stress and DNA impairment during seed germination (Nanda and Agrawal 2018 ).…”

Piriformospora indica (Hymenomycetes, Basidiomycota) is an endophytic fungus that colonises plant roots, and was originally isolated from Rajasthan desert. It is comparable to Arbuscular Mycorrhizal (AM) fungi in terms of plant growth promotional effects. P. indica has been used as an ideal example to analyse the mechanisms of mutualistic symbiosis. Major benefit of P. indica over AM fungi is that it is axenically cultivable in different synthetic and complex media. A preliminary attempt was made to scrutinise the role of P. indica co-cultivation on seedling vigour of common vegetables like Cucumis sativus L., Abelmoschus esculentus (L.) Moench, Solanum melongena L. and Capsicum annuum L. The positive effect of P. indica co-culture on seedling performance was compared to the effects of growth hormones like indole acetic acid and benzyl amino purine when supplemented to the MS medium at a concentration of 0.1 mg ml −1. An exogenous supply of auxin resulted in enhanced production of roots and cytokinin supplement favoured shoot production, whereas P. indica co-culture favoured simultaneous production of shoot and root over the control. P. indica colonisation inside the roots of C. sativus L. was also successfully established. These preliminary results indicate the prospective role of P. indica in vegetable farming through its favourable effect on plant growth.
