Notes:
Summary During anther development, characterized in maize plants with N cytoplasm, certain esterase isozymes in non-microspore cells decrease in amount with anther age and new isozymes appear in the developing microspores. In anthers from male sterile plants with cms T or cms C cytoplasm, neither of these changes in esterase patterns occurred. In anthers from plants with cms S cytoplasm, the decrease in the esterases of non-microsporogenous cells was observed but not the appearance of microspore esterases. In lines carrying cms S cytoplasm and nuclear restorer genes, esterase changes during anther development were as in normal fertile anthers. These results are discussed with respect to the phenomenon of cytoplasmic male sterility in the different maize genotypes.
