Transgenic corn with an improved phenotype due to the insertion of heterologous DNA whose transcription does not result in a known phenotype in corn. Enhanced phenotypes include redrawn, such as yield under stress conditions, and seed component content, vigor and stress tolerance, such as drought resistance, fungal resistance, ability to improve germination and growth with low temperatures, resistance to osmotic stress, resistance to insects, resistance to viruses; shadow tolerance, heat tolerance, reduced nitrogen tolerance and reduced phosphate tolerance; metabolic function, such as amino acid transport, protein production, enzymatic activity, growth, regulation and senescence of cells, increased capacity to produce ears under conditions of high plant density; and physiology, such as sterility and the time of germination, flowering and senescence. Said transgenic corn is obtained by generating a plurality of transgenic events for a plurality of unique transgenic DNA constructs, where each of the transgenic events comprises the introduction into the genome of a line of progenitor maize from a single transgenic DNA construct that It comprises a promoter operably linked to a sufficient amount of a heterologous DNA to produce transgenic cells that can be cultured to obtain transgenic corn plants with the improved phenotype. Claim 1: Transgenic corn seeds, characterized in that they have a higher yield (measured in crop weight per area) compared to the corresponding yield of the progenitor corn line, obtained by introducing into the genome of said progenitor line of a construction of Transgenic DNA comprising a promoter operably linked to a heterologous DNA, wherein said heterologous DNA encodes a protein whose amino acid sequence is at least 60% identical to a sequence selected from the group formed by SEQ ID N °: 368 to SEQ ID N °: 736. |
