The gametophytes of Arthromeris himalayensis are long lived (more than 110 days), and the advantage of long-lived gametophytic generation is to promote cross-fertilization (Klekowski, 1973, 1979).
With the encapsulation dehydration protocol, there was good survival of gametophytic tissue, with or without preculture on ABA, and this is similar to results found with gametophytes of several bryophytes, which do not require ABA preculture to survive encapsulation-dehydration freezing (Pence, 1998).
The first two are mostly controlled by the sporophytic genome, while the other two are primarily regulated by the gametophytic genome.
In addition to triggering the embryogenic program, the cell must cancel the gametophytic program.

This is very interesting, given the traditional lack of attention paid by taxonomists to gametophytic characters, a fact that is likely attributable to their reduced levels of morphological variation.
Unlike most algae, the zygote of Coleochaete remains attached to the gametophyte, becoming surrounded by a layer of protective cells (of gametophytic origin).

Additionally, ferns, especially in the gametophytic phase, are considered good indicators of environmental changes in the forest due to their sensitivity to the microclimatic and edaphic parameters (Page, 1979a, b).
