Pollen-mediated gene flow in wild olive
Wild olive (Olea europaea subsp. europaea var. sylvestris, aka oleaster) populations are subject to increasing fragmentation and size reduction. Beghè et al. employ microsatellite markers and apply paternity analysis to...

Leaf trait variation across the crown of isolated trees
Isolated trees subjected to high irradiance and concomitant stress may adjust leaf phenotypes across the tree crown. The plasticity in structural traits such as leaf angles or size can have profound consequences in the...
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.
Where do olives come from?
An analysis of patterns of genetic differentiation finds evidence of reciprocal gene exchanges between populations of Mediterranean and Saharan olives.

How does the vital interaction between pollen and pistil work?
How, in molecular terms, does the vital interaction between pollen pollen and pistil work?
Functional classification of olive pollen esterases
Pollen grains contain numerous hydrolytic enzymes, many of which are released upon contact with the stigma. Rejón et al. carry out for the first time a systematic functional classification of esterases in pollen grains...
Genetic diversity of ancient olive trees
Olive trees (Olea europaea) provide a good model to study the origin of cultivars due to their long lifespan. Diez et al. use SSR markers to evaluate genetic identity and diversity as well as phylogenetic relationships...
