摘要

Method for increasing the resistance of plants to viruses of the mosaic of sugarcane au00c7ucar and resistant plants of sugarcane mosaic virus - au00c7ucar. The present invention relates to a method for increasing the resistance of plants to infection by the virus of mosaic of sugar cane (SCMV).Such a method comprises transforming the plant with a transfectar or expression vector comprising a promoter operationally linked to a nucleic acid molecule encoding (I) a protein having properties of protein layer of said SCMV,Or (II) a molecule of RNA complementary to the tape antisenso positive RNA gene of coat protein, or (III) a molecule of dsRNA hairpin to the cover of said SCMV protein gene, where the expression of said tape of expression inhibits infection by SCMV.The present invention also refers to a transgenic plant, or a part, propagating material or offspring the same to be tolerant, resistant or immune to SCMV. The genome of this plant comprises one or more copies of a sequ00fau00eancia molecules nuclu00e9 acid.ICO coding for (I) a protein having properties of protein layer of said SCMV or (II) a molecule of RNA complementary to the tape antisenso positive RNA gene of coat protein, or (III) a molecule of dsRNA hairpin to the cover of said SCMV gene protein.
