Abstract excerpt

A novel allelic variant of the heat shock protein 101, designated neo-tetraploid rice fertility gene 1 (NTRF1), has been identified and is implicated in regulating fertility in neo-tetraploid rice (NTR); however, its regulatory mechanism remains unclear. In this study, we identified the ntrf1 mutant and demonstrated that its significantly reduced seed-setting rate was due to pollen developmental defects....
