Abstract Seed triacylglycerol (TAG), a major component of vegetable oil, consists of a glycerol esterified with three fatty acids. Vegetable oil has industrial applications and is widely used as edible oil. The increasing demand for plant oils, owing to population growth, it is crucial to enhance the oil content in seeds. We found castor WRINKLED1A (RcWRI1A) and R2R3-type MYB domain protein 306 (RcMYB306) which have homology with Arabidopsis WRI1 (AtWRI1) and AtMYB96 which regulate genes involved in fatty acid and TAG synthesis, respectively. These castor genes were separately and jointly overexpressed using seed-specific promoters in an oil crop, camelina ( Camelina sativa ). Overexpression of RcWRI1A , RcMYB306 , or RcWRI1A + RcMYB306 increased the total seed oil content in camelina. However, this increase was not significantly different from that observed during the overexpression of RcWRI1A or/and RcMYB306 . RcWRI1A overexpression increased the fatty acid content, including 16:0, 18:2, 18:3. Contrastingly, RcMYB306 overexpression increased the 18:1, 18:2, 18:3, 20:0 and 20:1 fatty acid. In the RcWRI1A + RcMYB306 lines, changes in fatty acid composition demonstrated the combined effects of these transcription factors. These results suggest that RcWRI1A and RcMYB306 can be used to improve the productivity of oil crops.
