Abstract excerpt
Minerals are stored in the aleurone layer and embryo during maize seed development, but how they affect endosperm development and activity is unclear. Here, we cloned the gene underlying the classic maize kernel mutant shrunken4 (sh4) and found that it encodes the YELLOW STRIPE-LIKE oligopeptide metal transporter ZmYSL2. sh4 kernels had a shrunken phenotype with developmental defects in the aleurone layer and...
