Provided are a parthenogenetic haploid induction gene DMP and an application thereof. The parthenogenetic haploid induction genes AtDMP8 and AtDMP9 are cloned from. Experiments have shown that mutations of AtDMP8 and AtDMP9 can produce parthenogenetic haploid inducibility, to enable dicotyledonous crops to be induced to produce haploids via parthenogenetic means. The present invention was further verified in tomatoes, and it was also found in tomatoes that the mutation of SlDMP can produce parthenogenetic haploid inducibility. The invention lays an important foundation for broadening the application of haploid breeding technology on dicotyledonous plants and revealing the biological mechanism of parthenogenetic haploid production. Given the universality of the utilization of haploid breeding technology in the current breeding industry, the invention has very wide application space and market prospects.

Parthenogenetic haploid induction geneand application thereof

The present invention discloses a maize parthenogenetic haploid-inducing gene ZmPLA1E and application thereof. The present invention utilizes the method of exchanged individual plant progeny tests for the first time, and successfully proves that the ZmPLA1E gene can generate and significantly increase the parthenogenetic haploid induction ability in the process of self-crossing or hybridizing as a male parent with other maize materials after the ZmPLA1E gene is mutated in the coding region. The haploid-inducing gene ZmPLA1E of the present invention is important for the cultivation of high-frequency parthenogenetic haploid inducing lines and the application of haploid technology.
