Fig. 9: Anthocyanin biosynthesis pathway in purple head Chinese cabbage.

From: The novel gene BrMYB2, located on chromosome A07, with a short intron 1 controls the purple-head trait of Chinese cabbage (Brassica rapa L.)

Fig. 9

gBrMYB2 with short intron 1 controls anthocyanin biosynthesis and accumulation through coexpression of BrTT8 and activation of a series of structural ABGs, such as BrF3’H, BrDFR1, BrANS1, BrUGTs, BrATs, and BrGSTs, resulting in a purple-head phenotype. Similarly, gBrmyb2 of common white head Chinese cabbage with long intron 1 completely represses anthocyanin biosynthesis by restricting the expression of Brmyb2 and ABGs, resulting in a nonpurple-head trait
