Microbial symbionts can alter plant physiological responses to both abiotic and biotic stress. Piriformospora indica, a root endophytic fungus, has been shown to enhance biomass production and confer tolerance to various abiotic and biotic stresses. Transcriptomics of soybean (Glycine max) colonized by P. indica and rhizobia showed that the fungus increases plant growth and nutrient utilization and may also stimulate production of lignin and secondary metabolites through the phenylpropanoid pathway. Overall, these results suggest that soybean maintains a symbiotic association with this root endosymbiotic fungus that improves both plant growth and nutrient acquisition and may modulate synergistic interactions with rhizobia.
