La vite è una pianta legnosa perenne di grande importanza economica in tutto il mondo. In natura, la vite è colonizzata da endofiti, cioè microrganismi che vivono nei tessuti della pianta e che migliorano la crescita della stessa. L’innesto è una procedura che viene usata come pratica comune per la propagazione della vite e del suo miglioramento, si vuole verificare se è in grado di mediare il trasferimento di endofiti nelle piante d’interesse. Per farlo si utilizzano viti provenienti da zone aride con una popolazione specifica di endofiti e si sfruttano nella procedura d’innesto associate a piante di vite coltivate in cella senza comunità microbica. L’obbiettivo di questo progetto di tesi è quello di mettere a punto un trasferimento degli endofiti tramite l’innesto, nello specifico di sfruttare un innesto di una vite con endofiti per far colonizzare una vite nesto che non li presenta. Per dimostrare l'efficacia del trasferimento di endofiti, si sviluppa in laboratorio una tecnica di crescita delle viti inoculate con batteri fluorescenti e si ripete l’innesto tra vite con endofiti e vite nesto senza.

Abstract
The vine is a woody perennial plant of great economic importance throughout the world. In nature, the vine is colonized by endophytes, that is microorganisms that live in the tissues of the plant and that improve its growth. Grafting is a procedure that is used as a common practice for the propagation of the vine and its improvement, we want to check whether it is able to mediate the transfer of endophytes in the plants of interest. To do this, vines from arid areas with a specific population of endophytes are used and they are exploited in the grafting procedure associated with vine plants grown in cells without microbial communities. The goal of this thesis project is to develop a transfer of endophytes through grafting, specifically to exploit a graft of a screw with endophytes to colonize a grafted vine that does not have them. To demonstrate the efficacy of endophyte transfer, a growth technique of inoculated vines with fluorescent bacteria is developed in the laboratory and grafting is repeated between grapevines with endophytes and graft graft without.File | Dimensione | Formato | |
