Interaction of the opaque-2 gene with starch-forming mutant genes on the synthesis of zein in maize endosperm

  • D. V. Glover


The combination of opaque-2 with starch-modified or starch-deficient mutants produced a cumulative and synergistic effect, respectively, in regulating zein synthesis. The double mutant, brittle-2 opaque-2, which almost completely prevented the synthesis of Z1 and Z2, had high RNase activity. The possible involvement of RNase in effecting zein synthesis is discussed.
