Abstract

Soybean plants producing soybean seeds comprising leghemoglobin are produced by modifying the genome of the soybean plant. Soybean plants, soybean seeds and soy protein compositions comprising leghemoglobin are provided. Soybean plants, soybean seeds and soy protein compositions comprising leghemoglobin and additionally one or more of high oleic acid, low linolenic acid, high protein, low stachyose, low raffinose and low protease inhibitors are provided. Protein compositions comprising leghemoglobin, such as soy isolates and concentrates can be made from the soybean seeds. Additionally, methods for generating and using plants, seeds and protein compositions comprising leghemoglobin are disclosed.
