Genetic diversity of Nostoc symbionts endophytically associated with two bryophyte species.

@article{citeulike:3033031, abstract = {The diversity of the endophytic Nostoc symbionts of two thalloid bryophytes, the hornwort Anthoceros fusiformis and the liverwort Blasia pusilla, was examined using the tRNA(Leu) (UAA) intron sequence as a marker.
