Puzzles in Moss Genome Evolution

Some plants have pairs of chromosomes, they’re diploid organisms like us. Other plants have more than two copies of chromosomes, they’re polyploid....

Associations between shoot-level water relations and photosynthetic responses to water and light in 12 moss species

In vascular plants, water and carbon economics are closely coupled. In mosses, this relationship has been little studied but a strong coupling is expected...

Solute transport inside feather moss stems

Feather mosses serve as important regulatory organisms for many ecological processes in boreal forests. They are generally considered to be ectohydric species, transporting water...

Single peat moss individuals include most of the allelic diversity in Sphagnum

Allopolyploids exhibit both different levels and patterns of genetic variation than are typical of diploids. Hitherto, little attention has been given to the apportioning...

Polyploidy and interspecific hybridization shape adaptation, speciation and evolution

About half of all higher plant species are recognizable as evolutionarily recent polyploids, where multiple whole genomes or sets of chromosomes have come together...

Botany really rocks!

For a plant life on the edge, like on a cliff face, should be peaceful. But Nigel Chaffey discovers one species has a real talent for annoying others.

Warming reduces stress in Antarctic moss

In moss-dominated regions of the Western Antarctic Peninsula, dramatic climate features have profoundly impacted moss biology and terrestrial ecology. In a study focused on...

Spore settling velocity to assess moss dispersal rates

The settling velocity of diaspores is a key parameter influencing dispersal ability in wind-dispersed plants but remains largely undocumented in bryophytes. Zanatta et al. measured...

Organellar phylogenomics of Sphagnum

Sphagnum (peatmoss) is rapidly developing as a model for ecological genomics research. Twenty or more species of Sphagnum often co-exist within peatlands and sort...

Stomata and atmospheric CO2 in bryophytes

This study strengthens the hypothesis of incremental rather than early acquisition of stomatal regulatory processes through land plant evolution.

Complex interplay of responses when plants experience canopy shading

Plants react to both decreased red:far red ratio and decreased photosynthetically active radiation, and in different ways.

Simulated Herbivory Leads Grasses to Pass Fungal Symbionts to Their Offspring

Many grasses host symbiotic fungi, Epichloë spp. These fungi can help grasses tolerate herbivory, or help repel herbivores. But how do these...

X-ray dose limits for microscopy lower than we thought

Subtle damage to hydrated tissue occurs at a far lower dosage than previously thought, and may be difficult to recognize.
