Plant development can be altered by transforming a plant with a genetic construct that includes regulatory elements and DNA sequences capable of acting in a fashion to inhibit pollen formation or function, thus rendering the transformed plant reversibly male-sterile. In particular, the present invention relates to the use of dominant negative genes and an anther-specific promoter. Male sterility is reversed by incorporation into a plant of a second genetic construct which represses the dominant negative gene. The invention also relates to novel DNA sequences which exhibit the ability to serve as anther-specific promoters in plants.

On peut modifier le développement de plantes par transformation d'une plante présentant une structure génétique comprenant des éléments régulateurs et des séquences d'ADN capables d'agir d'une manière inhibant la formation ou la fonction du pollen, conférant ainsi une stérilité mâle réversible à la plante transformée. L'invention concerne notamment l'utilisation de gènes dominants négatifs ainsi que d'un promoteur spécifique à l'anthère. La stérilité mâle est réversible par l'incorporation dans une plante d'une seconde structure génétique exerçant une répression sur le gène dominant négatif. L'invention concerne également de nouvelles séquences d'ADN capables de servir de promoteurs spécifiques à l'anthère dans des plantes.
