A gene ZmPLD3 for inducing maize maternal haploid production and its application thereof. Transgenic homozygous mutant plants or their progeny can be obtained by knocking out the ZmPLD3 gene in maize, and maize maternal haploids can be produced by hybridizing them as paternal materials with other maize materials. A series of allelic mutations of the gene having maternal haploid induction function through hybridization were obtained. The experiments showed that the mutation of maize phospholipase PLD3 could lead to the production of maize maternal haploid, which provides new thoughts for revealing the biological role of phospholipase in maize maternal haploid induction process. At the same time, the mutant individuals have the maternal haploid induction ability in maize, which is of great significance for breeding new types of haploid induction lines with high haploid induction rate and improving the efficiency of maize haploid breeding.
A method for inducing maternal haploids, comprising the following steps:
A method for preparing a maternal haploid induction line comprising silencing or knocking out a ZmPLD3 gene in the target plant genome to obtain a transgenic plant comprising a plant maternal haploid induction line;
