A METHOD FOR PROVIDING AND INHIBITING THE RICE FERTILITY, AND DISCERNING THE PRESENCE OF THE RICE RESTORER GENE BY USING THE RICE RESTORER GENE TO THE RICE BT TYPE CYTOPLASMIC MALE STERILITY

摘要

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 havin g 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 sequenc e 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 th e 38538- to 54123-positions in the base sequence represented by SEQ ID NO:27 a nd having a function of restoring fertility.
