Phenotypic analysis and molecular cloning of discolored-1 (dsc1), a maize gene required for early kernel development.

Abstract excerpt

Recessive mutations in the maize dsc1 locus prevent normal kernel development. Solidification of the endosperm in homozygous dsc1- mutant kernels was undetectable 12 days after pollination, at which time the tissue was apparently completely solidified in wild-type kernels. At later times endosperm did solidify in homozygous dsc1- mutant kernels, but there was a marked reduction in the volume of the tissue. Embryo...
