Figure 3From: A fertility restorer gene, Rf4, widely used for hybrid rice breeding encodes a pentatricopeptide repeat proteinPPR782a is expressed in various tissues with the highest expression in mature anthers. RT-PCR analysis of PPR782a in anthers at the meiotic stage (Mei), uni-nucleate microspore stage (Uni), bi-cellular pollen stage (Bi), and tri-cellular pollen stage (Tri), and in the leaf blades. PCR results obtained using genomic DNA is also shown.Back to article page
