CA 2293997

The present invention relates to an isolated nucleic sequence encoding the Ms45 male tissue-preferred regulatory region. In one aspect this invention relates to the use of this male tissue-preferred regulatory region in mediating fertility. An example of such use is the production of hybrid seed such as in a male sterility system. The Ms45 male tissue-preferred regulatory region can be operably linked with exogenous genes, such as those en-coding cytotoxins, complementary nucleotidic units and inhibitory molecules. This invention also relates to plant cells, plant tissue and differentiated plants which contain the regulatory region in this invention.

La présente invention concerne une séquence d'acide nucléique isolée qui code pour la région Ms45 régulant de préférence les tissus mâles. Un aspect de cette invention concerne notamment l'utilisation de cette région régulant de préférence les tissus mâles afin d'encourager la fertilité. Un exemple de cette utilisation est la production de graines hybrides, notamment dans un système de stérilité mâle. La région Ms45 régulant de préférence les tissus mâles peut être liée de manière opérationnelle à des gènes exogènes, par exemple les gènes codant pour les cytotoxines, les unités nucléotidiques complémentaires, et les molécules inhibitrices. Cette invention concerne enfin des cellules végétales, des tissus végétaux, et des plantes différenciées contenant la région régulatrice susmentionnée.
