ABSTRACT:
The present invention relates to the field of producing hybrid seeds, and specifically relates to the application of certain cloned nuclear fertility restorer genes, which restore male fertility to cytoplasmic male-sterile plants. In particular, the present invention relates to an enriched or substantially isolated nucleic acid sequence comprising a nucleotide sequence that hybridizes at least under moderately stringent conditions to SEQ ID NOS: 1, 3 or 4 and restores male fertility to a cytoplasmic male-sterile plant; a vector comprising such a sequence; an organism, virus, seed, plant cell, and plant comprising such a vector; methods for the production of hybrid seed; a method of producing a variant of a cytoplasmic male-sterile plant, and a method of suppressing cytoplasmic male sterility, all of which make use of the aforementioned nucleic acid sequences.
