About the Cover


Portion of an ear of corn showing the kernel phenotype obtained when the transposable element Spm excises from the opaque-2 locus during the course of endosperm development. Opaque-2 is a transacting regulator of seed storage protein expression. The opaque-mutable phenotype constitutes sectors of normal endosperm on an otherwise opaque (mutant) kernel. See page 960. [R. J. Schmidt, Brookhaven National Laboratory, Upton, NY 11973]
