  3. double mutant plants that harbor fls1kknock out in the pap1-D background (i.e., pap1-D/fls1ko plants) were generated, to examine whether anthocyanins can be further enhanced by blocking flavonol biosynthesis under PAP1 overexpression.

  4. Overexpression of FLS1 (FLS1-OX) not only altered seed coat color (resulting in a light brown color), but also affected flavonoid accumulation. Whereas fls1-3 mutants accumulated higher anthocyanin levels, FLS1-OX seedlings had lower levels than those of the wild-type.
