Abstract excerpt

The temporal regulation of the three homoeologous Wx genes, which direct amylose biosynthesis in wheat, remains unclear, hindering a systems-level understanding of this pathway. Using near-isogenic lines (NILs), we delineated their allele-specific regulatory hierarchy during grain filling. Amylose content decreased in a strict gene dosage-dependent manner, accompanied by a compensatory increase in the amylopectin...
