Blue Green Algal Association With Bryophytes

Blue-green Algal Association with Bryophytes

Certain mosses and liverworts are also known to be inhabited by blue-green algae.

The lower surface of the thallus of Anthoceros contains a species of Nostoc which stimulates the formation of papillae within the cavities of the host.

The papillae provide space for the formation of compact colonies of the alga, which in turn, help in the nitrogen nutrition of the host plant.

Nostoc sphaericum inhabits the cavities occuring on outgrowth near the edges of the lower surface of Blasia and Cavicularia (genera of liverworts).

The dependence of the host on the lower symbiont for its nitrogen nutrition has been established in the case of Blasia, using 15N.

Another instance of an association between a species of Hapalosiphon and Sphagnum (a moss) has also been cited in literature together with 15N data on translocation of fixed nitrogen.
