    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 from a plant with a wet stigma, Olea europaea. They find that olive pollen esterases can be classified into four functional groups: […] More

    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 among the oldest wild and cultivated olives of Southern Spain. The majority (90.4 %) of the a priori cultivated ancient olive genotypes […] More
