Abstract

La présente invention concerne des séquences de nucléotides médiatrices de la fertilité mâle des plantes et en décrit les séquences de molécules d'ADN et d'acides aminés. L'invention concerne également l'utilisation de ces séquences de nucléotides comme médiatrices de la fertilité des plantes. L'un de ces procédés consiste à utiliser un promoteur inducteur pour réguler l'expression de la molécule d'ADN. Les séquences de contrôle sont modifiées de façon que ce promoteur soit normalement sans effet, et qu'il en résulte pour les plantes une stérilité mâle. Lorsqu'on souhaite reproduire les plantes à stérilité mâle, on rétablit la fertilité mâle en traitant les plantes au moyen d'un agent chimique non phytotoxique inducteur de l'expression du gène critique.
