Description The expression of anthocyanin in the apiculus is dependent on the complementary
action of the color-producing genes (Cp and Ap). However, with these genes
alone, coloration is so limited and appears so thinly scattered at the very tip
of the apiculus that plants of this genotype are usually considered to be
colorless in ordinary outdoor observation. For distinct coloration in the
apiculus, the presence of the Pa gene is necessary. Pa is responsible for the
spreading of chromogenic substances over the entirety of the apiculus. The
majority of Japanese varieties or strains possess Pa.
