Rational Gene Stacking for Seed-Specific Carbon Partitioning to Simultaneously Enhance Lipid and Protein Contents in Arabidopsis

Increasing global population demands the development of oilseed crops such as canola-type Brassica napus L. and soybean varieties with high protein and oil content, despite the known negative correlation between them. We hypothesized that reallocating seed carbon from cellulose, a major compound of fiber, to these storage compounds via fine-tuned gene stacking could achieve this dual goal. We tested this hypothesis in Arabidopsis thaliana with a three-pronged gene stacking approach: (1) down-reg
