abstract = {Independent gametophyte ferns are unique among vascular plants because they are sporophyteless and
reproduce asexually to maintain their populations in the gametophyte generation. Such ferns had been
primarily discovered in temperate zone, and usually hypothesized with (sub)tropical origins and subsequent
extinction of sporophyte due to climate change during glaciations. Presumably, independent fern
gametophytes are unlikely to be distributed in tropics and subtropics because of relatively stable climates
which are less affected by glaciations. Nonetheless, the current study presents cases of two independent
gametophytes fern species in subtropic East Asia. In this study, we applied plastid DNA sequences (trnL-LF
and matK + ndhF + chlL datasets) and comprehensive sampling (~80 %) of congeneric species for
molecular identification and divergence time estimation of these independent fern gametophytes. The two
independent gametophyte ferns were found belonging to genus Haplopteris (vittarioids, Pteridaceae) and
no genetic identical sporophyte species in East Asia. For one species, divergence times between its
populations imply recent oversea dispersal(s) by spores occurred during Pleistocene. By examining their ex
situ and in situ fertility, prezygotic sterility was found in these two Haplopteris, in which gametangia were
not or very seldom observed, and this prezygotic sterility might attribute to their lacks of functional
sporophytes. Our field observation and survey on their habitats suggest microhabitat conditions might
attribute to this prezygotic sterility. These findings point to consideration of whether recent climate change
during the Pleistocene glaciation resulted in ecophysiological maladaptation of non-temperate independent
gametophyte ferns. In addition, we provided a new definition to classify fern gametophyte independences
at the population level. We expect that continued investigations into tropical and subtropical fern
gametophyte floras will further illustrate the biogeographic significance of non-temperate fern gametophyte
independence.}
