Abstract excerpt
During maize (Zea mays L.) domestication, seed protein content sharply declined1,2. In plants, glutamine and asparagine levels are closely correlated with protein content3,4. Asparagine is synthesized from glutamine, a process catalysed by asparagine synthase5. Teosinte harbours a superior haplotype of asparagine synthase 4 (ASN4)2. Here, we report that teosinte also possesses a superior haplotype gene promoting...
