Abstract excerpt

Ideal plant architecture optimizes canopy structure and increases grain yield in maize. However, its underlying genetic mechanisms remain poorly characterized. Two recessive, EMS-induced maize mutants were identified that have reduced stature, opaque kernels, and abnormal subsidiary cell division and are allelic to Opaque1 (o1) which encodes myosin XI-I. These 2 new missense alleles, o1-2995 and o1-tan62, unlike...
