Method for obtaining transgenic plants, intregration vector used and plants obtained.

摘要

The invention relates to a method for obtaining transgenic plants for the purpose of endowing them with long-lasting tolerance to plant viruses by integration in their genome of genetic information coding for the expression of molecules of satellite nucleic acid, wherein the DNA sequence coding for the expression of the satellite nucleic acid is introduced into the genome in the form of a single monomeric unit whose ends optionally possess foreign sequences.
