摘　　要：Rising demands for protein worldwide are likely to drive increases in livestock production,asmeat provides-40%of dietary protein.This will come at a significant environmental cost,and a shift toward plant-based protein sources would therefore provide major benefits.While legumes provide substantial amounts of plant-based protein,cereals are the major constituents of global foods,with wheat alone accounting for 15–20%of the required dietary protein intake.Improvement of protein content in wheat is limited by phenotyping challenges,lack of genetic potential of modern germplasms,negative yield trade-offs,and environmental costs of nitrogen fertilizers.Presenting wheat as a case study,we discuss how increasing protein content in cereals through a revised breeding strategy combined with robust phenotyping could ensure a sustainable protein supply while minimizing the environmental impact of nitrogen fertilizer.
