Some plant leaves are blue, but have no blue pigments. How does that work?

Extra blue-light receptors helped ferns thrive in early angiosperm forests
Leptosporangiate ferns have three times more cryptochrome receptors than their nearest relatives.

New Equisetum phylogeny provides insight into an ancient lineage
The first divergences among horsetail species occurred with the break-up of Pangaea.
Hungry for fungi: green mycoheterotrophic plants are far more common than previously thought
A surprising number of plants snack on fungi as well as sunshine.

Cyanobacteria: Good week, or bad week..? Part III
This is the third of our quartet of posts looking at the newsworthy world of the blue-greens. Image: David Fuchs / Wikipedia Asteroids, bad for dinosaurs, but good for cyanobacteria? This really good news for...

Plant economics spectrum theory holds true within ferns
Plants usually have limited resources in one way or another. There is only so much nutrient in the soil. How best to use it? The plant economics spectrum theory integrates the coordination of plant functional traits...

A fern thought to grow on trees still keeps a root on the ground
The Aspleniaceae is a family of ferns, some of which are terrestrial and some of which are epiphytes. A new study has found a rarity, a hemiepiphyte.

Ecophysiology of early lineage vascular plants
Tropical understory communities are highly diverse, and plants in these environments must optimize functional traits to ensure ecological and evolutionary success. Campany et al. survey the ecophysiology of two spore...

Characterization of the satellitome in lower vascular plants: the case of the endangered fern Vandenboschia speciosa
Vandenboschia speciosa is a highly vulnerable fern species, with a large genome (10.5 Gb). Haploid gametophytes and diploid sporophytes are perennial, can reproduce vegetatively, and certain populations are composed...
Conserved thermal performance curves across the geographic range of a gametophytic fern
Species-level responses to environmental change depend on the collective responses of their constituent populations and the degree to which these populations are specialized to local conditions. Thermal tolerance limits...

Stomatal cell wall composition: distinct structural patterns in different phylogenetic groups
Stomata are pores regulating gas exchange in land plants. Stomatal morphology has remained largely consistent through ∼400 million years of plant evolution, though cell wall composition has changed. Shtein et al...

With fronds like these… foliar dimorphism and reproduction in ferns
Ferns use their leaves for both reproduction and carbon fixation. How do they manage to use one organ to tackle two very different jobs?
Why should we investigate the morphological disparity of plant clades?
Macroevolution of major clades is often studied by plotting their taxonomic diversity through time. It is equally informative, but less commonplace, to investigate how clades explore anatomical ‘design’ space by...
Sporogenesis and offspring ploidy levels in hybrid Dryopteris ferns
In ferns, apomixis is an important mode of asexual reproduction. Although the mechanisms of fern reproduction have been studied thoroughly, most previous work has focused on cases in which ferns reproduce either...
