Microbiome and symbiotic partner’s functions in the lichen L. pulmonaria. The mycobiont is responsible for the holobionts’ morphology, mechanical stability and reproduction, protects and supports the photo- and cyanobiont and shapes the microbial community. The photobiont is in charge of the photosynthetic carbon fixation. The cyanobiont is responsible for nitrogen and carbon fixation. The detailed role of the lichenicolous fungi is unclear. The microbiome plays a role in nutrient, vitamin and trace element supply, in resistance to abiotic factors and in antagonizing biotic impact.
