Method of gene expression modulation in plants, vectors, use of vectors and use of SCDHN, SCLNC and SCTIP2-3 genes

摘要

method of modulating gene expression in plants, vectors, use of vectors and use of scdhn, sclnc and sctip2-3 gene promoters The present invention relates to a method of modulating gene expression in sugarcane through the use of of promoters isolated from genes with expression profile induced by water deficit in leaves, stem and roots or preferably in sugarcane roots. In addition, the present invention relates to the use of three nucleotide sequences that act as promoters of the regulation of genes encoding a dehydrin (scdhn), a non-coding long transcript (sclnc), and an intrinsic tonoplast protein 2-3 ( sctip2-3) for activation of genes of interest in transgenic plants in order to increase productivity and abiotic stress tolerance.
