✦ Synopsis
Stable cell suspension cultures have been established from immature endosperms of A69Y wild-type and opaque-2 maize (Zea mays L.). Cultured cells are capable of storage protein (zein) synthesis and accumulation throughout the growth period. Electrophoretic patterns of zeins show, for opaque-2 cells, the preferential inhibition of the accumulation of 22 kDa peptides typical of the mutation. Viable protoplasts, able to regenerate cell walls, as well as to divide and to express foreign DNA in transient expression experiments, can be obtained with high yields from cultures of both genotypes.
