Explanation:
Detailed explanation-1: -A chemically synthesised cecropin B gene, usually found in the giant silk moth (Hyalophora cecropia), has been introduced into tomato plants and in vivo studies show significant resistance to bacterial wilt and bacterial spot.
Detailed explanation-2: -In that case, an “anti-freeze” gene that helps flounder survive frigid waters was spliced into tomato cells to enhance the plant’s resistance to cold. The fish-tomato didn’t swim, nor did it ever make it to market.
