Actinostachys minuta, a new species of grass fern from Mindanao, Philippines [PDF]
Actinostachys minuta Amoroso & Coritico (Schizaeaceae), from Mindanao, Philippines, is described herein as a new species. This species is distinguished from all other species of Actinostachys (grass ferns) by its notably short and narrow fronds ...

Sequencing of small RNAs of the fern Pleopeltis minima (Polypodiaceae) offers insight into the evolution of the microrna repertoire in land plants. [PDF]
MicroRNAs (miRNAs) are short, single stranded RNA molecules that regulate the stability and translation of messenger RNAs in diverse eukaryotic groups. Several miRNA genes are of ancient origin and have been maintained in the genomes of animal and plant ...

The galls are structures formed of plant tissues in response to the activity of different types of organisms, especially by insects. As a consequence of an intimate relationship with their host plants, most of these insects have a very narrow host range.

Mycobiome detection from a single subterranean gametophyte using metabarcoding techniques
Premise Several ferns and lycophytes produce subterranean gametophytes, including the Ophioglossaceae, Psilotaceae, and some members of the Schizaeaceae, Gleicheniaceae, and Lycopodiaceae.

Epiphytism in ferns: diversity and history
As for other vascular plants, numerous adaptive strategies have been selected in epiphytic ferns in order to survive in a constraining and desiccating environment and thus to prevent dehydration and/or to access to water and nutrients. Here we present some of the specializations that allow ferns to survive in this particular habitat.

Evolution of epiphytes in Davalliaceae and related ferns [PDF]
The evolution of epiphytes in Davalliaceae was investigated by field observations and molecular phylogenetic analyses. Field studies revealed that in Davalliaceae and related ferns, epiphytes in a broad sense are classified into climber, secondary hemi-epiphyte, and obligate epiphyte, based on combinations of the places (ground vs.

Cellular basis of ABA-induced de novo meristem formation and sex-type conversion in Ceratopteris gametophytes. [PDF]
SUMMARY Meristems house pluripotent stem cells and sustain continuous growth and organogenesis in land plants. Unlike seed plants, whose gametophytes lack meristems, fern gametophytes initiate and maintain meristems, enabling growth independently from sporophytes. In the model fern Ceratopteris richardii, gametophytes develop into either hermaphrodites

How Epiphytic Are Filmy Ferns? A Semi-Quantitative Approach
Similar to plants in many other families, members of the Hymenophyllaceae use numerous substrates for growth, e.g., soil, rocks or tree bark. However, substrate preference does not only differ among species but can also vary among members of the same species. There have been several attempts in the past to appropriately capture this variation, but none

Pterobius itiokai Maruyama, gen. n. and sp. n., (Coleoptera: Scarabaeidae: Aphodiinae) is described from Lambir Hills National Park, Borneo based on specimens collected from a Crematogaster difformis ant nest in the myrmecophytic epiphytic fern genus ...
