The article presents an analysis of the 3D models for maize (Zea mays L.) gynogenesis proteins (MTL/NLD/PLA1, DMP7/DUF679, BBM1) with spontaneous mutations in the nucleotide sequences of their coding genes. It was found that the four-nucleotides insertion into the Zm_Mtl/Nld/Pla1 gene sequence of haploid-inducing Stock 6 maize line changes the amino acid composition of the β-fold and leads to the replacement of two α-helices with an unstructured section. A single nucleotide substitution of the Dmp7/Duf679 gene in the haploid-inducing CAU5 maize line leads to a change in the α-helix position and the 3D model protein DMP8/DUF679 conformation. On the other hand, the single nucleotide substitutions in the Zm_Bbm1 gene in AT-4 maize line do not lead to a change in the amino acid composition and conformation of the BBM1 protein.
