The article presents an analysis of the secondary, tertiary structures and conformation changes in 3D protein models as a result of spontaneous mutations in genes associated with maize (Zea mays L. ) gynogenesis and embryogenesis. In particular, it was found that the of four-nucleotides insertion into the ZmMtl/Nld/Pla1 gene sequence leads to substitution of two α-helices with an unstructured section and a change in the amino acid composition of one of the β-folds in haploid-inducing (Stock 6, ZMS-8, ZMS-P) maize lines. The SNP at 131 position from the ZmDmp7 gene starting codon change the α-helix position in the haploid-inducing line CAU5 change, unlike the ZMS-8 line, which has a similar SNP and two additional amino acid substitutions. On the other hand, the SNP in the ZmBbm1 gene from parthenogenetic line AT-4 and ZmCenH3 gene of haploid-inducing (ZMS-8, ZMS-P), and control (KM) maize lines do not lead to the amino acid substitutions in the corresponding proteins.
