Photobionte lichen
WebAbstract. Lichens are dual organisms formed from a symbiotic association of a fungus, the mycobiont, and an alga and/or cyanobacterium, the photobiont, in which numerous photosynthetic cells are intertwined in a matrix of fungal hyphae. Such definitions raise the question as to whether lichens are technically individual organisms. WebLichens are the symbiotic phenotype of nutritionally specialized fungi, ecologically obligate biotrophs which acquire fixed carbon from a population of minute photobiont cells …

WebMar 29, 2024 · Within our dataset, co-occurrence of at least two Trebouxia species-level lineages—intrathalline photobiont diversity—was observed in 30.7% of the lichen samples ( Figure 3C ). The highest percentage of co-occurrence is found in thalli collected in the altitudinal range 1,500–2,000 m a.s.l.
WebAccording to the LIVE/DEAD staining results, the lichen photobiont showed an average viability rate of 71%, whereas the even more resistant lichen mycobiont showed a rate of 84% (Brandt et al. Reference Brandt, de Vera, Onofri and Ott 2015). Successful recovery of photosynthetic activity if properly re-activated was demonstrated. WebA lichen looks like a single organism, but it is actually a symbiotic relationship between different organisms. It is composed of a fungal partner (mycobiont) and one or more …

WebLichens are a well-known symbiosis between a host mycobiont and eukaryote algal or cyanobacterial photobiont partner(s). Recent studies have indicated that terrestrial lichens can also contain other cryptic photobionts that increase the lichens’ ecological fitness in response to varying environmental conditions.
