Potential risk of photo-damage in Antarctic photosynthetic organisms

Light is indispensable for photosynthetic organisms, but excess light energy causes damage in photosystems and readily leads to cell death in severe environments such...

The impact of asexual and sexual reproduction on spatial genetic structure in Marchantia

Sexual reproduction requires close proximity of mates, but ensures genetic variation in the local population. Although independent of cross-pollination, asexual reproduction can however, reduce...

Funaria hygrometrica gametophyte and sporophyte cuticular waxes

The waxy cuticles that coat plant surfaces have been relatively well studied in vascular plant taxa, but it is unclear how similar they may...

Embryonic moss sporophytes can be hardened to desiccation tolerance

Embryos of the moss Aloina ambigua are inducibly desiccation tolerant (DT), requiring a slow-dry period to confer tolerance to air-dryness. Hardening to DT describes...

No sexual niche partitioning in a dioecious moss

Roughly half of the species of bryophytes have separate sexes (dioecious) and half are hermaphroditic (monoecious). This variation has major consequences for the ecology...

Sporophyte desiccation tolerance in the moss Aloina

Stark and Brinda study cultured sporophytes and vegetative shoots from a single genotype of the moss Aloina ambigua.

Moss: is the mother protecting the offspring, or holding it back?

Jessica M. Budke adds another dimension to a recent paper about the development of the calyptra in moss. Is there parent-offspring conflict?

Maternal cuticle protects moss offspring from dehydration

Funaria hygrometrica calyptra may represent the earliest occurrence of maternal protection via structural provisioning of a cuticle in green plants.

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...

Changes in How a Plant Breathes Aren’t Always Matched by Changes in Its Anatomy

You can't predict how a Yucca gloriosa will react to drought from its anatomy alone.

New grapevine model better predicts whole-canopy gas exchange

Models considering only the maximum photosynthetic capacity for all leaves over-estimated net carbon dioxide exchange by nearly a third.

Plants from different climates can react to drought in similar ways

How do plants react when circumstances change? One method can be to evolve a local adaptation. Another can be be phenotypic plasticity,...
