Abstract: Plants are produced that express an amino acid sequence that, when administered to a fish, produce an antigenic or immune response in the fish. The amino acid sequence in one embodiment is an antigen from an organism that causes pathology in fish. The plant tissue may be fed to the fish, or mixed with other materials and fed to fish, or extracted and administered to the fish.
Abstract: Expression of a recombinant manganese-dependent peroxidase in plants is described. Methods for the recovery of transgenic corn seeds that express high levels of functional manganese-dependent peroxidase are also provided. Manganese-dependent peroxidase vectors are engineered to contain sequences directing seed-preferred expression as well as sequences for cell wall-targeted localization.

Abstract: Production of proteases in plants is set forth, whereby heterologous DNA encoding the protease is introduced into the plant and expression of the protein achieved. By such methods, expression is achieved in plants wherein the plant cell is not damaged, the protein can be recovered without contamination by other proteases, and can be expressed at levels such that commercial production of the enzyme is obtained. Expression levels can be at 0.1% of total soluble protein of the plant, or higher.
