VITISEC-MOMA: next-generation sequencing and ARN to study the grapevine microbiome

The Project VITISEC-MOMA is leaded by Villanueva nursery (Larraga, Spain) and has the participation of the BIOVITIS group at the “Instituto de Ciencias de la Vid y del Vino (ICVV)” in Logroño, Spain. The objective of this industrial research and experimental development project is to improve the phytosanitary quality of the propagation material by studying the impact of hot-water treatment (HWT) on the grapevine microbiome. We will investigate the diversity of the active fungal communities by targeting the RNA molecules. In addition, we will evaluate the genotype-specific influence over the fungal microbiome. The global budget is 458,376 euros and the project supported by CDTI. The project will be developed during 30 months.

Hot water treatment is used for pest and pathogen control in dormant cuttings and rooted vines. For example, the Eutopean Food Safety Authority (EFSA) recently recomended HWT as the most effective treatment to eliminate the bacterium Xylella fastidiosa, causal agent of Pierce’s disease, and its subspcies from grapevine propagating material.
