Abstract
Provided herein are methods and compositions for restoring fertility and maintaining sterility in plants. In particular, one method disclosed includes introducing into a male-sterile plant, wherein the plant comprises one or more homozygous mutations in a male-fertility gene, a plant restoration donor chromosomal component comprising a plant-derived polynucleotide that confers a plant phenotypic marker linked to a male-fertility restoration locus that functionally complements the male-sterility phenotype from the one or more homozygous mutations in the male-sterile plant. In some examples, the plant-derived polynucleotide that confers a plant phenotypic marker and the male-fertility restoration locus are linked to each other and located on the same chromosomal arm on the plant restoration donor chromosomal component. In some examples, the plant-derived polynucleotide that confers a plant phenotypic marker, the male-fertility restoration locus, or both are modified.
