Insights into the evolutionary history and widespread occurrence of antheridiogen systems in ferns
New Phytologist, 2020 Summary Sex expression of homosporous ferns is controlled by multiple factors, one being the antheridiogen system. Antheridiogens are pheromones released by sexually mature female fern gametophytes, turning nearby asexual gametophytes precociously male ...

What We Do (and Don't) Know About Ferns: Dryopteris (Dryopteridaceae) as a Case Study [PDF]
, 2015 Ferns are the second largest group of vascular land plants after the angiosperms, but remain chronically underrepresented in studies of plant phylogeny, biogeography, physiology, and genomics.

Ferns are less dependent on passive dilution by cell expansion to coordinate leaf vein and stomatal spacing than angiosperms. [PDF]
PLoS ONE, 2017 Producing leaves with closely spaced veins is a key innovation linked to high rates of photosynthesis in angiosperms. A close geometric link between veins and stomata in angiosperms ensures that investment in enhanced venous water transport provides the ...
