Lichen algae remodel their cell walls in response to drying

Lichen algae respond to desiccation with both a controlled collapse of their cell walls and a bit of biochemical remodelling.

What are holocentric chromosomes good for?

Possessing holocentric chromosomes may confer an advantage in clastogenic conditions and environments.

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...

The lachrymatory tale of the barnacle and the bacterium

For Valentine's Day Nigel Chaffey finds a tale of an unlikely couple who have set up home together, though it ends in tears.

Ecophysiology of recalcitrant seed persistence

Dominant tree species in northern temperate forests, for example oak and beech, produce desiccation-sensitive seeds. Despite the potentially major influence of this functional trait...

Dehydration rate and ROS production in an aquatic moss

Desiccation induces an increase of reactive oxygen species (ROS) in chloroplasts, mitochondria and peroxisomes as cellular water content decreases. Cruz de Carvalho et al. examine...

Is the moss calyptra covered by a cuticle?

Over a century ago, the gametophytic calyptra was predicted to be covered by a cuticle that protects the sporophyte apex from desiccation. Budke et...
