INVINH1 Gene Alleliс Polymorphism in Maize Accessions from VIR Collection
The sequences of the apoplast invertase inhibitor gene INVINH1 were identified in 71 maize accessions from the VIR collection. In total, 35 INVINH1 allelic variants were found. In 21 maize accessions, at position –95 from the start codon, INVINH1 contained an extended insertion (143, 190, 192, and 210 bp). In INVINH1 proteins, 21 amino acid substitutions have been identified, six of which, predicted to be radical, were localized in the PMEI functional domain (A49V, A49G, A65P, S97I, C99R, D108Y).
