A proposed model for BnWRI1 in regulating lipid anabolism and flowering in B. napus. BnWRI1 up-regulates transcript levels of genes involved in glycolysis, FA synthesis, and lipid assembly to enhance accumulation of oil (TAG), galactolipids, and phospholipids. The increased MGDG and DGDG by BnWRI1 promote source/sink capacity, thus BnWRI1 plays a positive role in homeostasis among sugars, TAG, and membrane lipids in B. napus. Moreover, BnWRI1 also enhances FT expression, and PC level to accelerate flowering.
