Genotypic influence in the juvenile to adult transition in olive seedlings.

Olive breeding is a long process and any improvement in shortening the juvenile phase is highly desirable. In the present study, the effect of olive tree parents in different agronomic characteristics have been evaluated during four years in 520 olive genotypes generated from three different crosses in three different experimental fields, all located in Andalusia region, Spain. The crosses evaluated are 'Arbosana' x 'Sikitita' and its reciprocal, whose parents are characterized by being early bearers; and 'Frantoio' free pollinated, whose mother variety is characterized by having a long unproductive period.

Pollen production in olive cultivars and its interannual variability.

Background And Aims: Olive (Olea europaea subsp. europaea var. europaea) is the most extensively cultivated fruit crop worldwide.

Use of fine capillaries for cryopreservation of Caenorhabditis elegans by vitrification.

Caenorhabditis elegans is an exceptional model organism. More than twenty thousand different strains have been developed, increasing knowledge on countless topics. However, the traditional method to cryopreserve this nematode, based on slow freezing, usually reaches recovery rates of around 35% for the L1 and L2 larval stages.

Efficiency of breeding olives for resistance to Verticillium wilt.

Olive trees are the most cultivated evergreen trees in the Mediterranean Basin, where they have deep historical and socioeconomic roots. The fungus develops inside the vascular bundles of the host, and there are no effective applicable treatments, making it difficult to control the disease. In this sense, the use of integrated disease management, specifically the use of resistant cultivars, is the most effective means to alleviate the serious damage that these diseases are causing and reduce the expansion of this pathogen.

Implementation of esophageal endoscopic submucosal dissection in Spain: Results from the nationwide registry.

Introduction And Aims: The outcomes of endoscopic submucosal dissection (ESD) in the esophagus have not been assessed in our country. Our primary aim was to analyze the effectiveness and safety of the technique.

Material And Methods: Analysis of the prospectively maintained national registry of ESD.
