Metabolic engineering is a discipline of plant biotechnology that seeks to genetically modify plant metabolic pathways to generate plant varieties with improved well being advantages. Not too long ago, scientists engineered potato and tomato crops to precise the plant pigment betalain — discovered solely in Caryophyllales and better fungi. They discovered that whereas betalain-tomatoes conferred anti-inflammatory results towards macrophages and murine colitis, betalain-potatoes confirmed no such results.
