Transcriptomic Evidence of Adaptive Evolution of the Epiphytic Fern Asplenium nidus.

ABSTRACT: Epiphytic ferns have been found to flourish after angiosperms dominated forest communities, and they play important roles in rainforest canopies. How do epiphytic ferns adapt to tropical rainforest canopy habitats? At present, we know little about the molecular mechanism underlying this adaptation. Asplenium nidus is a well-known epiphytic fern that is closely related to the terrestrial species Asplenium komarovii. Here, RNA-seq and comparative transcriptomic analyses were performed to explore the underlying basis of the adaptation of A. nidus to extreme environments. A total of 44.04 and 44.57 Mb clean reads were obtained from A. nidus and A. komarovii, respectively, and they were assembled into 89,741 and 77,912 unigenes. Functional annotation showed th
