A newly identified protein that is encoded by a polynucleotide sequence associated with cytoplasmic male sterility restorer activity (Rf3) is described. The cytoplasmic male sterility restorer gene can be inserted through breeding introgression into plant genomes to restore cytoplasmic male sterility in plants. Further applications of the newly identified polynucleotide sequence associated with cytoplasmic male sterility restorer activity include a mutation (rf3) which results in cytoplasmic male sterility. The cytoplasmic male sterility restorer gene can be inserted through breeding introgression into plant genomes to result in cytoplasmic male sterility in plants. Methods for detecting the cytoplasmic male sterility restorer (Rf3) and the cytoplasmic male sterility (rf3) gene sequences are further described.

Maize cytoplasmic male sterility (CMS) S-type restorer gene Rf3

The present disclosure provides a method for selecting a plant comprising a functional restorer gene for maize S-type cytoplasmic male sterility comprising the steps of (a) screening a population of plants for at least one marker nucleic acid, wherein the marker nucleic acid comprises an allele linked to the functional restorer gene for maize S-type cytoplasmic male sterility; (b) detecting the marker nucleic acid; (c) identifying a plant comprising the marker nucleic acid; and (d) selecting the plant comprising the marker nucleic acid, wherein the plant comprising the marker nucleic acid further comprises the functional restorer gene for maize S-type cytoplasmic male sterility. The present disclosure also provides methods for restoring fertility in a progeny of an S-type cytoplasmic male sterile plant and methods for transferring an Rf3 gene into a progeny plant.

A novel maize variety designated 3AAXI2080 and seed, plants and plant parts thereof are provided. Methods for producing a maize plant comprise crossing maize variety 3AAXI2080 with another maize plant are provided. Methods for producing a maize plant containing in its genetic material one or more traits introgressed into 3AAXI2080 through backcross conversion and/or transformation, and to the maize seed, plant and plant part produced thereby are provided. Hybrid maize seed, plants or plant parts are produced by crossing the variety 3AAXI2080 or a locus conversion of 3AAXI2080 with another maize variety.

Maize inbred 3AAXI2080

This disclosure concerns high-resolution mapping and candidate gene cloning of Rf4, a maize restorer of fertility gene that restores fertility to C-type cytoplasmic male sterility. The disclosure also relates to molecular markers that are tightly-linked to, or reside within, the Rf4 gene. In some embodiments, methods are provided whereby hybrid seeds may be produced from crosses of a male plant comprising nucleic acid molecular markers that are linked to or that reside within the Rf4 gene and a female plant carrying C-type CMS.
