METHOD FOR GENERATING ISOGENIC MAIZE DERIVATIVES WITH IMPROVED PROPERTIES, BY MEANS OF GENE OVEREXPRESSION.

摘要

The invention relates to a method for obtaining isogenic derivatives of any variety of maize, having improved properties, such as resistance to adverse environmental conditions, for example drought and high temperatures, while offering improved growth and grain yield. The method of the invention for obtaining said derivatives of any variety of maize produces an isogenic maize line, i.e. plants that have the same genetic make-up as the original variety, but that are characterised in that they overexpress some genes, in particular associated with osmoprotection, thermotolerance and protection of photosynthetic activity. The invention is particularly characterised in that it offers genetic improvement without incurring the insertion of heterologous DNA (autogenic or isogenic maize) since it comprises the use of a gene from the same plant, which is simply being overexpressed.
