It is intended to provide a method of imparting or controlling fertility to rice BT−male sterility cytoplasm and a method of judging the existence of a fertility restoring gene. In these methods, use is made of a nucleic acid having the base sequence represented by SEQ ID NO:27 or a nucleic acid having a base sequence showing at least a 70% identity with the base sequence represented by SEQ ID NO:27 and having a function of restoring fertility. Alternatively, use is made of a nucleic acid having the base sequence consisting of the bases at the 38538− to 54123−positions in the base sequence represented by SEQ ID NO:27 or a nucleic acid having a base sequence showing at least a 70% identity with the base sequence consisting of the bases at the 38538− to 54123−positions in the base sequence represented by SEQ ID NO:27 and having a function of restoring fertility.

L'invention concerne un procédé permettant de conférer ou de réguler la fertilité d'un cytoplasme à stérilité mâle de riz BT, et un procédé d'estimation de la présence d'un gène de restauration de la fertilité. Les procédés décrits utilisent un acide nucléique comportant la séquence de bases représentée par SEQ ID NO :27, ou un acide nucléique comportant une séquence de bases qui présente au moins 70 % d'identité avec ladite séquence, et qui possède une fonction de restauration de la fertilité. Un autre mode de réalisation utilise un acide nucléique comportant la séquence de bases constituée par les bases des positions 38538 à 54123 de la séquence représentée par SEQ ID NO :27, ou un acide nucléique comportant une séquence de bases qui présente au moins 70 % d'identité avec la séquence constituée par les bases des positions 38538 à 54123 de la séquence représentée par SEQ ID NO :27, et qui possède une fonction de restauration de la fertilité.
