Abstract: A method for maintaining a male sterile plant in a homozygous recessive state includes providing a first plant that includes homozygous recessive male sterility alleles, providing a second plant that includes homozygous recessive male sterility alleles the same as that in the first plant and a nucleotide construct in which the construct exists in a heterozygous state. The first nucleotide sequence of the nucleotide construct encodes a first protein that restores male fertility of the first plant after expression in the first plant. The second nucleotide sequence of the nucleotide construct allows for distinguishing the grains with or without the construct by observation through naked eyes or devices. The first nucleotide sequence and the second nucleotide sequence are tightly connected with each other and coexist in a plant. The method further includes fertilizing female gametes of the first plant with male gametes of the second plant.

Abstract: 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.
