photobiont
Noun
Meaning
photobiont (plural photobionts)
A photosynthetic symbiont, especially those in symbiosis with fungi in lichen.
Examples
A photobiont may be associated with many different mycobionts or may live independently; accordingly, lichens are named and classified as fungal species.
These fragments can take the form of soredia, dust-like particles consisting of fungal hyphen wrapped around photobiont cells.
It is possible that the photobiont triggers otherwise latent genes in the mycobiont.
