Genetic and Phenotypic Characterization of a Novel dull1 Allele Affecting Starch Accumulation in Maize
The novel <i>du1</i> allelic variant, <i>du1-2018</i>, disrupts starch biosynthesis in maize endosperm, leading to reduced starch accumulation, altered starch structure, and transcriptional changes in nitrogen-related metabolic pathways. Our results provide new insights into the regulatory mechanisms underlying SSIII function in starch synthesis and endosperm development, and suggest potential links to carbon/nitrogen balance, with implications for future genetic improvement of maize grain quality.
