"...Plants get their characteristic pigmentation from chloroplasts, tiny organelles in each cell that carry out photosynthesis. The chloroplasts in these specimens have been reprogrammed to churn out custom-engineered proteins with amazing properties. Some have rendered rodents immune to malaria, cholera, polio, and plague. Others have protected dogs from allergic reactions to blood-clotting proteins that can trigger fatal anaphylactic shock in hemophiliacs who need them.
