Genetic Variations and Haplotype Diversity of the Wheat FRIZZY PANICLE (WFZP) Gene in 98 Aegilops tauschii Accessions

<i>WFZP</i> homeolog exhibited high conservation with no functional variants in the key AP2/ERF domain. Haplotype characterization identified five haplotypes (Hap-D1 to Hap-D5) based on nine single-nucleotide polymorphisms, five of which induced single amino acid residue substitutions downstream of the AP2/ERF domain. Hap-D1 (identical to <i>Triticum aestivum WFZP-D</i>) and Hap-D2 are two most common. Hap-D1 is concentrated in Iran and Azerbaijan, primarily associated with ssp. <i>strangulata</i>, while Hap-D2 displays broad distribution across the range and primarily belongs to ssp. <i>tauschii</i>. The remaining haplotypes (Hap-D3/4/5) are identified in ssp. <i>tauschii</i> accessions. These findings suggest that strategic integration of ssp. <i>tauschii</i> into wheat-breeding programs could enhance genetic diversity. The identified natural variations provide potential haplotype resources for improving wheat yield potential.

Abstract

<i>WFZP</i> homeolog exhibited high conservation with no functional variants in the key AP2/ERF domain. Haplotype characterization identified five haplotypes (Hap-D1 to Hap-D5) based on nine single-nucleotide polymorphisms, five of which induced single amino acid residue substitutions downstream of the AP2/ERF domain. Hap-D1 (identical to <i>Triticum aestivum WFZP-D</i>) and Hap-D2 are two most common. Hap-D1 is concentrated in Iran and Azerbaijan, primarily associated with ssp. <i>strangulata</i>, while Hap-D2 displays broad distribution across the range and primarily belongs to ssp. <i>tauschii</i>. The remaining haplotypes (Hap-D3/4/5) are identified in ssp. <i>tauschii</i> accessions. These findings suggest that strategic integration of ssp. <i>tauschii</i> into wheat-breeding programs could enhance genetic diversity. The identified natural variations provide potential haplotype resources for improving wheat yield potential.
