Maize Mutants Defective in Embryogenesis.

Abstract

The data discussed in this note refer to the characterization of mutants with defective embryogenesis: emb (embryo specific) mutants, exhibiting a phenotype suggestive of specific defects in embryogenesis and abs (aborted seed) mutants affected in an early stage of embryo and endosperm development. Table 1 reports the list of mutants included in this study and their prominent features, while Table 2 refers to their immature embryo growth in vitro. The mutants have been generated by Mu or Ac transposon mediated mutagenesis. At the molecular level, the presence of a co-segregating polymorphism may provide a means by which the disrupted genes may be cloned
