Floral colour evolution in Nicotiana polyploids
Do floral colour shifts accompany allopolyploidy (interspecific hybridization and genome multiplication) in the genus Nicotiana (Solanaceae)?

Theoretical approach to predicting petal wettability
This model predicts petal surface wettability by considering the additive effects of the geometries of the epidermal cells and the structured cuticle.

High molecular diversity in rare European Sorbus domestica
Unexpectedly high levels of molecular diversity are found within populations of Sorbus domestica, irrespective of their location.

Pollen dispersal and breeding structure in Petunia
Results show that most pollen dispersal in subsp. axillaris occurs within populations and there is a high proportion of inbreeding.

Defoliation, tree growth and storage of C and N
Although lenga beech trees, completely defoliated by caterpillars of Ormiscodes amphimone, do not die, they show reduced growth for at least 2 years.

Chilling tolerance of C4 photosynthesis in Miscanthus
A study finds relatives of Miscanthus ×giganteus with significantly superior capacity for photosynthesis at chilling temperatures for the first time.

How tree species fill geographic and ecological space
Ricklefs analyses local assemblages of deciduous trees and finds that the forests in question do not appear to be saturated with species.

Phylogeny and evolution of Cyperus esculentus
Results suggest that tiger nut probably originated in the late Cenozoic in Africa and reached the Americas repeatedly, independently of Columbian exchanges.

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.

Zygomorphy evolved from disymmetry in Fumarioideae
Floral bilateral symmetry (zygomorphy) has evolved at least 70 times during the history of angiosperms, whilst radial symmetry (actinomorphy) is the ancestral and most common state

Fast-growing trees rely on reserves for new spring growth
Uscola et al. use isotope labeling to study carbon and nitrogen movements in new spring growth in seedlings of 4 coexisting Mediterranean evergreen trees.

Mechanisms for ethylene-induced aerenchyma formation
Results suggest that ethylene is perceived in all maize root tissues and cortical-cell-specific PCD is controlled downstream of ethylene perception.
