Deletion of maize RDM4 suggests a role in endosperm maturation as well as vegetative and stress-responsive growth

Abstract Opaque kernels in maize may result from mutations in many genes, such as OPAQUE-2. In this study, a maize null mutant of RNA-DIRECTED DNA METHYLATION 4 (RDM4) showed an opaque kernel phenotype, as well as plant developmental delay, male sterility, and altered response to cold stress. We fou...
