Aspen, they grow up so… weirdly.
Aspen possesses enormous levels of
genotype-based intraspecific variation.

When does Acacia koa know it’s time to grow up?
Sometimes the best strategy for a young plant is not the same as the best strategy for an old plant. Some heteroblastic plants can switch how they grow but what triggers this?

Rising tides bring rising salinity to coastal plants, but will they cope?
Rising sea levels mean increased salinity for plants on the shore, but how well do coastal plants cope with salt? New research says they're surprisingly bad at it.
Fusoid cells: a developmental approach in Poaceae
In mature grass leaf blades as seen in cross-section, oblong cell-like structures have been interpreted most recently as intercellular gas spaces delimited by successive collapsed fusoid cells. These cells have been...

The relative weight of ontogeny, topology and climate in the architectural development of three North American conifers
Knowledge of plant architecture allows for the retrospective study of plant development, and through modelling and simulation this development can be linked to environmental constraints and to predict responses to...

Evidence that divergent selection shapes a developmental cline in a forest tree species complex
Evolutionary change in developmental trajectories (heterochrony) is a major mechanism of adaptation in plants and animals. However, there are few detailed studies of the variation in the timing of developmental events...

On nectaries and floral architecture
Nectaries are the most interesting organs in flowers – at least to me. Compared to other floral organs (i.e. perianth organs, stamens and carpels), the position of nectaries is not necessarily fixed within the floral...

The benefits of sleeping in
The early bird catches the worm, but does the frost catch the early plant? A new article in AmJBot says there are advantages for a plant to germinate late.
Nectary development and floral architecture in Geraniaceae and Hypseocharitaceae
A closer look at the flowers of Geraniaceae and Hypseocharitaceae reveal organs coming together to produce something new.
Trunk epicormics and growth in Fagus sylvatica
Epicormic shoots in European beech, Fagus sylvatica, may be associated with decreased radial growth. Colin et al. study the number of axillary buds, shoot length, ring width profiles, epicormic shoots and other...
Ontogeny and responses to apical damage
Plants can tolerate tissue loss through vigorous branching, often triggered by release from apical dominance and activation of lateral meristems. In the annual plant Medicago truncatula, Gruntman and Novoplansky show...
Growth and carbon budgets in Nothofagus
Growth decline with age in trees is hypothesized to be an effect of carbon limitation. By assessing carbon reserves and isotopes at different ontogenetic stages in the deciduous broadleaf tree Nothofagus pumilio (lenga...
Physical dormancy and the water gap in Geranium
Physical dormancy and the water gap in <i>Geranium</i> A water gap is a small opening that forms on breaking of dormancy in physically dormant seeds or fruits. Gama-Arachchige et al. examine the development...
