Abstract
The application discloses a gene KNU for controlling navel orange male sterility and application thereof. The nucleotide sequence of the gene KNU for controlling navel orange male sterility is shown as SEQ ID NO:1. The amino acid sequence of a protein KNU for controlling navel orange male sterility encoded by the gene KNU for controlling navel orange male sterility is shown as SEQ ID NO:2. The application identifies a key gene KNU for controlling male sterility and seedlessness from navel orange and its back-mutants. The gene KNU is a gene specifically expressed in anther somatic cells, and through a Cas9 editing mode citrus material, precise breeding of male sterility and seedless citrus can be realized. The application first provides a target gene KNU for controlling citrus male sterility and seedlessness.
