Genoplante-Valor

Kernel productivity of plants through the modulation of glutamine synthetase activity

The invention relates to a method for improving the kernel productivity of a maize plant, wherein said method comprises overexpressing in said plant at least one glutamine synthetase isoenzyme, in order to increase the number and/or size of kernels.

GENOPLANTE-VALOR

Increased kernel productivity of plants through the modulation of glutamine synthetase activity

The current invention provides the promoter of the Zea mays nuclear gene encoding glutamine synthetase. Compositions comprising this sequence are described, as are plants transformed with such compositions. Further provided are methods for the expression of transgenes in plants comprising the use of these sequences. The methods of the invention include the direct creation of transgenic plants with the cytoplasmic glutamine synthetase promoter by genetic transformation, as well as by plant breeding methods. The sequences of the invention represent a valuable new tool for the creation of transgenic plants, preferably having one or more added beneficial characteristics.
