This plant biology study investigates the TaWI12 gene in wheat (Triticum aestivum L.), which is involved in flower development, particularly pistillody (conversion of stamens into pistils). Researchers cloned and analyzed three TaWI12 homoeologs (4A, 4B, 4D) and used CRISPR/Cas9 gene editing to study its function.
Key findings:
Overexpression of TaWI12 in Arabidopsis led to filament shortening and reduced growth.
CRISPR/Cas9 mutations in wheat resulted in pistillody and leaf cracking.
TaWI12 is highly homologous to wound-induced proteins in Hordeum vulgare and Aegilops tauschii, suggesting a role in stress response.
Pistillody mutants may offer insights into improving wheat yields through genetic modifications.
This research contributes to understanding floral organ development in wheat and potential applications in high-yield breeding.
