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

Winter warming delays dormancy release, advances budburst, alters carbohydrate metabolism and reduces yield in a temperate shrub
Global climate models predict an increase in the mean surface air temperature, with a disproportionate increase during winter. Since temperature is a major driver of phenological

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.

Extrafloral nectar and above- and below-ground herbivory
The highest EFN production in seedlings of Triadica sebifera (tallow tree )is induced by above-ground herbivory when below-ground herbivores are absent.
