A class of small non-coding endogenous RNAs known as microRNAs (miRNAs) plays a major role in post-transcriptional gene regulation during plant development and plant responses to biotic and abiotic stresses. It has been suggested that the miRNA pathway contributes to pathogen...

The microbiota colonizing the rhizosphere and the endorhizosphere contribute to plant growth, productivity, carbon sequestration, and phytoremediation. We characterize the rhizosphere bacterial and fungal microbiota across five grapevine rootstock genotypes cultivated in the...

Spontaneous fermentation is the most traditional way and a low-intervention method for conducting alcoholic fermentation in wineries, giving rise to the most complex wine profiles. However, inoculation with single culture inocula of Saccharomyces cerevisiae...

Esca and leaf stripe diseases are two of the most destructive grapevine trunk diseases which are caused by a complex of fungal species, being the Ascomycete Phaeomoniella chlamydospora the most frequently isolated species from affected vines. To date, no curative measures are...

Grapevine powdery mildew is a disease caused by the fungus Erysiphe necator that entails such seriousness that if the environmental conditions are favourable and the handling is not adequate, it can cause the total loss of the harvest.
In La Rioja AOc this disease is...
